How to Feed a Digester for High Biogas Output The Weltec MULTIMix Way.

Avoid problems with inconsistent throughout quality, and avoid downtime when feeding a digester with, grass silage, whole-plant silage, and manure for biogas production.

With the MULTIMix digester feed delivery system, WELTEC BIOPOWER offers, a unique solution which removes foreign materials, BEFORE being conveyed to the feed pump.

The system also shreds the substrate to a size and consistency which is optimised, for rapid uptake by the biogas bacteria.

The MULTIMix system thus ensures the technical and economic stability of biogas plants, by preventing failures, and thus ensuring an uninterrupted process of digestion of the substrates used.

Advantages of Installing a Weltec MULTIMix:

1, Processes fibrous, sticky and soft substrates (up to a high dry weight percentage).
2, Provides bacteria-oriented substrate shredding for immediate biogas production.
3, Ensures an optimum loading of the digester with a homogeneous, macerated bio-suspension.
4, Minimises the risk of floating and sediment layers.
5, Improves overall anaerobic digestion plant energy efficiency, through the reduction of agitation energy needed, and significantly increases the pump feed pump's typical service life.
which substantially reduces wear and tear.

Two quick MULTIMix tips, for biogas plant operators, follow:

Tip 1, Several digesters can be fed with only one MULTIMix.
Tip 2, A MULTIMix unit can easily be retrofitted to your biogas plant.

IADAB News Weekly - Edition 4: Clean Energy Growth Strategy to Estonian Biogas State Support

The IADAB Anaerobic Digestion and Biogas News Weekly - Issue 4: 13 October 2017

This is Issue 4 of the IADAB News Weekly where we summarise the most important news of the week in the developing world of the Anaerobic Digestion and Biogas Industry in the UK and globally!

IF YOU WANT A SUMMARY OF THE CONTENTS OF THIS NEWSLETTER WATCH THE FOLLOWING VIDEO. OTHERWISE SCROLL DOWN TO READ THE MORE DETAILED VERSION.


We are a UK based newsletter, so this week we start with the biggest story for UK readers. This is the publication of the UK Government's Clean Growth Strategy, which is being seen as unequivocally good news for the UK AD and Biogas industry. 

Then we follow that, in Item 2, with news from IKEA, the all-conquering European home store business. IKEA this week announced that it will support the development of biomethane service stations in Finland, indicating a huge leap forward for renewable transport fuel use. Where Finland leads others will surely soon follow.

In item 3, the Finnish are in the news again. Scroll down for a news story "double" from Puregas Solutions, who whilst becoming the UK North East's fastest growing company, have also just been acquired by Finnish company Wärtsilä: The self-proclaimed; "global leader in advanced technologies and complete life-cycle solutions for the marine and energy markets".

Finally, as if, just to confirm the ascendancy of anaerobic digestion and biogas Europe-wide, is the news that Estonian companies will soon be able to begin applying for state subsidies for the production of biomethane,

So, in a week that once again has been good news for the industry, let’s get started…

Item 1: UK Clean Growth Strategy Welcomed by ADBA – But Food Waste Collections Needed

UK readers will be presently surprised that, contrary to what the mainstream UK media would have you believe. The government under leader Theresa May, is not totally paralysed by Brexit negotiations, but is making domestic policy, with the publication of the UK Clean Growth Strategy.

The organisation’s Chief Executive, Charlotte Morton said:
“The multi-faceted nature of AD means that, with the right support, Anaerobic Digestion can play a central role in decarbonising heat, electricity, transport, and farming, as well as recycling organic wastes, increasing energy and food security, and restoring the UK’s degraded soils. No other technology can make such a key contribution to so many different areas of the Clean Growth Strategy."
“We welcome the government’s ambition to divert all food waste from landfill by 2030 and to support local authorities in rolling out separate food waste collections. We look forward to BEIS’s new Resources and Waste Strategy, which will need to be supported by meaningful funding and legislation to effect the scale of change needed for an urgent transition to a more circular economy."
“We also welcome the strategy’s highlighting of the importance of best practice in AD. ADBA’s pioneering, industry-led Best Practice Scheme, which will be launched in full later this year, will help support AD operators in meeting the highest environmental, health and safety, and operational standards."
“The publication of the Clean Growth Strategy today is a welcome sign that the government is starting to think about how we can make the deep emissions cuts that will be necessary to meet the Fourth and Fifth Carbon Budgets over the next 15 years.
What is needed now is tangible support for AD in the form of the following:
  • Urgent tabling of legislation on the Renewable Heat Incentive to renew support for biomethane-to-grid;
  • A long-term replacement for the Feed-In Tariff to support small-scale renewable electricity generation;
  • Mandatory separate food waste collections in England to allow AD to recycle this vital and underused resource; and
  • A new support system for farmers that rewards carbon abatement and incentivises the use of biofertiliser to restore soils.”
via UK Clean Growth Strategy Welcomed by ADBA – But Food Waste Collections Needed

Item 2: IKEA Supports Development of Biomethane Service Stations in Finland

Gasum has signed a comprehensive circular economy cooperation agreement with IKEA Finland.

UK Clean Energy Growth Strategy to Estonian Biogas article image.


The cooperation will involve using food waste from IKEA restaurants in Finland to produce biogas, with Gasum filling stations also to be constructed in conjunction with IKEA stores. The first station will be opened at the IKEA store in Espoo in late 2017. The Finnish IKEA stores will be the first IKEA units in the world to get natural gas stations.

“Utilizing the volumes of food waste remaining after our efforts to eliminate wastage is a sustainable act for the promotion of a clean energy form, biogas. As a company we’re determined to set a good example by adopting new circular-economy approaches and hopefully at the same time inspiring consumers as well as other companies to take concrete environmental action,” 
said, Country Sustainability Manager Tiina Suvanto from IKEA Finland. via IKEA supports development of biomethane stations in Finland

Item 3: Wärtsilä to Acquire Biogas Upgrader - Puregas Solutions Who Also Receive Status of UK NE Region's Fastest Growing Company

The company utilizes the unique CApure process to convert raw biogas to biomethane and renewable natural gas. The CApure process recovers more than 99.9% of the biomethane present in the raw biogas. The process separates the CO2 from the biogas by a process ... via Wärtsilä to acquire biogas upgrader Puregas Solutions

The technology enables the company to upgrade raw biogas to biomethane/Renewable Natural Gas for direct injection into the gas grid, compression for vehicle fuelling (bioCNG) or liquefied to provide bioLNG (liquefied natural gas) ... via Sunderland's Puregas Solutions named North East's fastest growing company

Item 4: Estonian Government to Give State Support to Biomethane

Estonian companies will be able to begin applying for state subsidies for the production of biomethane, according to ERR news.

Estonia’s goal is for fuel produced from renewable sources to make up 10% of total fuel consumption by 2020, of which biomethane would account for one third. The measure aimed at boosting the use of Estonian made, environment-friendly biomethane will be financed with proceeds from the auctioning of carbon dioxide emission credits... via Estonian government to give state support to biomethane 

So, the message to the AD and Biogas industry this week is to plan for expansion, ahead of many new opportunities likely to flow from the news of this last week...

Remarkable Uses for Sewage Sludge Including Producing Biogas

What could possibly be the use for all that mucky filthy smelly sewage sludge? 
NEVERTHELESS, We found some remarkable uses for Sewage Sludge, Including producing biogas. 

Sewage sludge, which is the by-product of the treatment of our foul sewage in wastewater treatment works on first sight would seem to be a useless material, but is it? We set out to find out, and the result is this article. Scroll down to see that.

Meanwhile maybe you would like to watch our video about the specific use which is listed below: "Remarkable uses for Sewage Sludge, Including producing biogas". enjoy the video!


1. Hygienize It and Spread It on Land: 

If spread on land it will raise soil-available phosphorous says Wikipedia (see below). That's a good outcome for the growth of crops, but raising soil salinity is not so good, so we guess we had better keep looking. 
Use of sewage sludge has shown an increase in level of soil-available phosphorus and soil salinity, also heavy metals build-up. The findings of a 20-year field study of air, land,confirmed this ... via Sewage sludge - Wikipedia

2. Use it as Alternative Fuel source in the Cement Industry: 

An attractive disposal method for sewage sludge is to use it as alternative fuel source in the cement industry. The resultant ash is incorporated in the cement matrix. via Use of Sewage Sludge in Cement Industry - BioEnergy Consult

4. Make Coal: 

Carbonscape out of New Zealand microwaves and compresses organic matter – wood chips, corn stalks and even sewage – into eco-coal. It burns like regular coal, but the carbon doesn't come deep from the ground. Renewable Fuel Technology, meanwhile, has devised a modified version of the Fischer-Tropsch process to convert organic matter into coal. Organic matter gets converted to syngas first.

5. Produce Biogas and Purify that Into Pipeline-Grade Methane: 

BioEnergy Solutions builds, maintains and operates the anaerobic manure digesters that convert manure into methane. The process isn't entirely green – carbon dioxide in the gas from the manure has to be burned off before the methane can be sent down a pipeline – but it does eliminate many of the hazards associated with manure. Revenue can also be generated through carbon credits and selling the solids as cow beds or fodder for, maybe some day, organic flooring or building materials. via 11 Great Things to Do With Sewage | Greentech Media

6. Make a Sludge Compost Using USDA's Method:  

When sewage sludge and woodchips are mixed and composted, as by the Beltsville aerated pile method (Willson et al., 1980),!/ a stabilized product results from the action of aerobicthermophilic microorganisms, which utilize a part of the organic material for their growth and activity. During this decomposition, the composting biomass heats to temperatures in the pasteurization range of 55*^ to 70^C, with resulting destruction of enteric pathogenic microorganisms. The end result is a humuslike material useful as a soil conditioner and a source of plant nutrients. It is essentially free of human enteric pathogens and offensive odors. via Sludge Compost as - USDA 

7. Extract Gold from Sewage Sludge! 

In some sites, "concentrations of gold in sewage sludge are sufficiently high for recovery to be ... The USGS has explored ways to remove potentially dangerous metals from treated sewage that is used as fertilizer and also pursued the possibility of ... via There's Gold In Them Thar Sewage Pipes, Swiss Researchers Say

8. Use Sewage Treatment Plants Sludge toEnsure Greenery at 4 Parks: 

Secondary treated sewage will be further treated using chlorine. The settled sludge is sent for recirculation to the equalisation tank. The dry sludge coming out of the system can be used as manure. According to officials, this will be rolled out to other ... via Sewage treatment plants to ensure greenery at 4 parks

9. Extract energy from Sewage Sludge:



A water company says new techniques can help it extract 90% of calorific value from sewage sludge.

Thames Water is planning to greatly increase the amount of energy it can extract from sewage sludge.

The water company can currently only extract half of the calorific value – the energy contained in raw sewage – from the sludge it treats by using anaerobic digestion (AD) to turn it into gas.

However, external affairs and sustainability director Richard Aylard told the London Infrastructure Summit yesterday (October 2017) that the company was developing new AD methods that could nearly double the amount of energy it can use.

“That will get us to 90% and also massively reduce the amount of residue that has to go out to farms,” Aylard told delegates. via Thames Water to increase energy extraction from sewage

10. New Technology Turns Poo Sewage Sludge to Petroleum-Like Biocrude Oil
A team of scientists from the Pacific Northwest National Laboratory (PNNL) at the US Department of Energy has found a way to reuse sewage sludge into biocrude oil, turning human waste into reusable fuel.

According to the study published by the PNNL, the researchers has devised a simple technology called hydrothermal processing (HTP). 

During HTP, sewage sludge is pressurized to about 3,000 pounds per square inch and then put into a reactor (a pressurized tube that's extremely hot at 660 degrees Fahrenheit). 

The heat in the reactor enables the cells in the sludge to break down, forming tow by-products: biocrude oil and "an aqueous liquid phase" that can be transformed into other kinds of chemical products.

"HTP converts organic material into biocrude oil, natural gas, or both, with potentially more than 99% conversion of organics. HTP uses the same processes which form fossil fuels, (heat, pressure, time, and water), but amplifies these conditions so the conversion occurs in a much shorter timeframe. 

This technology is specifically designed for wet feed stocks. The byproduct is clear, sterile water," the Water Environment & Reuse Foundation (WERF) told Treehugger.

We hope you agree that there are some truly remarkable uses for sewage sludge!

IADAB News Weekly - Edition 3: From a New ADBA Industry Guide to a Growing Network of UK AD Plants

The IPPTS Anaerobic Digestion and Biogas News WEEKLY

This is Issue 3 of IADAB News Weekly in which we summarise the most important news of the week in the fast moving world of the Anaerobic Digestion and Biogas Industry in the UK, and globally! 

This week has seen the publication of articles on a variety of subjects. Watch our intro video about this newsletter below an then scroll down, and read our summary of those articles which interest you;


The highest popularity has been an article on Linked-in with 82 Linked-in likes, explaining how anaerobic digestion facilities protect the environment. 

Following that with 15 Twitter likes is the new AD Industry Guide from ADBA, and a Science Direct Article about AD and nitrogen removal. 

If that's too high-brow for you, and you want some more practical news, we have AD Plant leader Tamar Energy discussing their growing AD plant network.



Alright, let’s get started…

1. AOE and Other Anaerobic Digester Facilities Protect Environment by Transforming Organic Waste Into Fertilizer and Clean Energy

Focusing on energy and fertiliser within this article they say:

BIOGAS

Charles Vigliotti, AOE’s chief executive, told The New York Times Magazine that the biogas produced at his facility could generate an astounding nearly 50 million kilowatt-hours of electricity per year. This [reduces the methane which would otherwise leak into the atmosphere producing environmental damage] and the newly harnessed energy will help power his facility, and can be sold to an electric company, and may also be used to fuel its fleet of trucks.

HIGH-NUTRIENT WATER AND FERTILIZER

The U.S. consumes close to 20 million tons of commercial fertilizer each year, according to the U.S. Department of Agriculture. And through the last 30 years, nitrogen fertilizer use has increased at a faster rate than phosphate and potash. Anaerobic digestion can produce organic fertilizers that typically contain many plant nutrients.

Click image to see a larger version.


[Anaerobic digestion helps protect the environment here as well.] Here’s how it works: After an anaerobic digester processes waste, what’s left is a material called digestate. In some parts of the world, that digestate is used to irrigate farm fields. In AOE’s case, the biogas company partnered with Scott’s Miracle-Gro to create high-nutrient water that eventually becomes organic nitrogen fertilizer. Organic fertilizers are also known to be slow-working, which decreases the chances of harming plants, unlike chemical-based fertilizers.

Even during a period in which governments and citizens alike are becoming more familiar with clean, renewable energy, it’s likely the notion of creating fuel to power trucks or entire facilities—or even water that can be used in organic fertilizer—would seem out of reach.

Not so, thanks to innovative companies such as American Organic Energy. via AOE & Other Anaerobic Digester Facilities Protect Environment By Transforming Organic Waste Into Fertilizer & Clean Energy

2. PRESS RELEASE: ADBA Releases Revamped AD Industry Guide

The Anaerobic Digestion and Bioresources Association (ADBA) has today released the second edition of The Practical Guide to AD, a key guidance document for developing and operating anaerobic digestion (AD) facilities in the UK.

ABDA Practical Guide to AD, cover image.
The Guide covers key topics of relevance to AD operators, including feedstocks, producing and using biogas and biomethane, digestate, planning, regulation, funding and insurance, training, and health and safety.

Over 50 contributors, a team of reviewers, and external stakeholders fed in their expertise and knowledge to update the Guide with the latest regulatory, policy and technological developments in the AD sector.

AD plants recycle organic wastes and convert purpose-grown crops into renewable heat and power, low-carbon transport fuel, and nutrient-rich biofertiliser. AD plants in the UK currently have enough capacity to power over a million homes as well as producing a range of co-benefits such as reducing greenhouse gas emissions, supporting UK farmers, decarbonising large vehicles, and recovering resources from wastes.

The Guide will be a living document, updated online periodically in line with developments in the AD industry.

3. Nitrogen removal during anaerobic digestion of wasted activated sludge under supplementing Fe(III) compounds

Anaerobic ammonium oxidation coupled to Fe(III) reduction, i.e., Feammox, is playing an important part in nitrogen cycle of natural environments, which however has been rarely investigated in waste water/solid treatment processes. 

Ammonium as a byproduct of nitrogenous substance decomposition during anaerobic digestion of waste activated sludge usually presents a quite high content and poses a great risk to environment.

This study focused on investigating the effects of supplementing Fe(III) compounds in anaerobic digestion of sludge and especially evaluating the roles in nitrogen removal.

Feammox Process Diagram
(c) Feammox

Supplementing magnetite, Fe2O3 and Fe(OH)3 in anaerobic digesters all increased the methane production and sludge reduction. 

Importantly, these Fe(III) compounds induced Feammox to occur continuously. 

NO2- and NO3- were generated in the Fe(III)-added reactors, especially in Fe(OH)3-added reactor. 

Afterwards, NOx- would be reduced with organics or Fe(II) as electron donors. Consequently, 20.1% of total nitrogen was removed in Fe(OH)3-added reactor after 40 days. 

As a product of dissimilatory iron reduction (including Feammox), the Fe(II) content was far less than theoretical production through the stoichiometrical NH4+ removal in Feammox, implying that the Fe(II) /Fe(III) cycle likely occurred to trigger the successive nitrogen loss.

IADAB News Weekly - Edition 2: New Food Waste (FW) Plants, FW from Strawberries, WRAP Tackling FW & Irish Feed-in-Tariff

Date: 29 September 2107

It’s Friday the 29 September 2017, and this is Issue 2 of IADAB News Weekly, where we summarise the most important news of the week in the developing world of the Anaerobic Digestion and Biogas Industry, in the UK and globally! 

Alright, let’s get started… This week's news, has been all about food waste, feed-in-tariffs. We did not plan it that way, but when researching this weeks articles we simply found it has coincidentally been the topic of the week.

Scroll down to find out about how:
  • Britcon has completed a £32m AD Plant For ReFood
  • How £30m of Food Waste is created in the UK from strawberries and lettuce processing alone, and
  • According to WRAP what can be done to reduce this waste.
  • Last but not least; How in New York the development of food waste Anaerobic Digestion facilities is transforming organic waste into fertiliser and clean energy.
Watch our video intro to this page below here:


And Finally; we move away from food waste to report on:
  • Irish Plans for a New Feed-in-Tariff to create a rapid step up in their renewable energy use
  • How a Young Staffordshire Farmer is establishing his own AD Business, all before he reaches the age of 30. 
Those stories are coming up right after this....

Britcon Completes £32m AD Plant For ReFood

Britcon has successfully completed on the contract to deliver a new, £32m anaerobic digestion (AD) plant in Dagenham for food waste recycler ReFood (UK) Ltd.

The new £32m plant in Dagenham is the most advanced integrated AD plant dedicated to food waste in the south of England.

The gas to grid (G2G) facility is capable of recycling 160,000 tonnes of food waste each year generating 14 million m3 of biogas.

Using G2G technology this is upgraded to reflect the qualities of natural gas – allowing it to be injected directly in to the national grid and used to power 12,600 homes across the region. via CIWM Journal


£30m Food Waste Created From Strawberries and Lettuce Processing Alone, Says WRAP

New research from WRAP, published today, has highlighted the significant financial, environmental and efficiency benefits inherent in tackling food waste in primary production, as it showed that an estimated £30m of UK strawberry and lettuce produce ended up as waste in 2015.

WRAP has also announced a series of sector-wide projects tackling food waste in primary production that have brought together farmers, growers, producers, hospitality and food service businesses and retailers through the organisation’s Courtauld Commitment 2025. via CIWM Journal

US News: Biopower Reports on a New York Development of Food Waste Anaerobic Digester Facilities Transforming Organic Waste Into Fertilizer and Clean Energy

When it comes to food and the sheer volume discarded annually, the United States reportedly ranks as one of the largest organic waste generators in the world. Each year, the United States discards up to 60 million tons of produce, according to a recent estimate. 
Businesses in New York City alone send about 650,000 tons of food waste annually to nearby landfills—a staggering and extraordinary amount of organic material that the city is aggressively trying to manage. 
Large cities, such as New York, are recognizing the problem and taking action. Of immediate concern are already overburdened landfills, where organic waste decays and decomposes, spawning harmful greenhouse gas emissions and toxic ozone pollution.  ...
Instead of dumping the waste in landfills, scraps are diverted to organic waste sites and transformed into renewable energy.  
One such company doing just that is Yaphank-based American Organic Energy (AOE), which New York Gov. Andrew Cuomo credited as a model for harnessing renewable energy. 
AOE will accept 180,000 tons per year of food waste, 30,000 tons of fats, oil, and greases, and an additional 10,000 tons of gas clippings.
BIOGAS 
Charles Vigliotti, AOE’s chief executive, told The New York Times Magazine that the biogas produced at his facility could generate an astounding nearly 50 million kilowatt-hours of electricity per year.  This newly harnessed energy will help power his facility, can be sold to an electric company, and may also be used to fuel its fleet of trucks.

Ireland: New Feed-in Tariff Promotes Biogas Potential

In the course of 2017, Ireland intends to initiate their energy reform with a new feed-in tariff for renewable energies. The government plans to increase the amount of green electricity from the current figure of about 23 percent to 40 percent by 2020. 

The tariff system is to establish a favourable environment for biogas plant operation. 

In view of the extensive agricultural and waste resource potential available in Ireland, WELTEC BIOPOWER UK will showcase its AD plant technologies at the Energy Now Expo Ireland, which will be held in the end of October in The Hub in Kilkenny.

In early September, the Irish Department of Communications, Climate Action & Environment (DCCAE) announced the adoption of a new subsidy regime to promote renewable energies, to be known as the Renewable Energy Support Scheme (RESS). So far, Ireland has been the only European country without an incentive scheme for heat from renewable sources. However, the green island has to meet EU requirements by 2020. via Weltec News and Events

Young Farmer Securing the future with Anaerobic Digestion

Young Farmer Rob Greenow has successfully established his own AD business, allowing him to secure his future in agriculture, all before the age of 30.

Combining an interest in renewable energy with his farming experience, Staffordshire-based Rob established AD management business, BioG UK, just a couple of years after leaving university.

“While studying at Reading University I completed my dissertation on ammonia volatisation and the spreading application types of digestate from AD Plants,” he explained. 
“At the time AD was only just becoming popular in the agricultural industry but I could see the future potential. 

So, after graduation, I joined an AD company and was involved in the planning and running of various sites.

“But, in 2012 I decided to go it alone and set up BioG UK, hoping that one day I would be able to establish my own AD plant.” 

Although Rob intially hoped to support farmers through the feasibility and planning stages of an AD plant build, he found that the business soon changed direction.

“After two years I shifted the focus of the business to concentrate on helping existing AD plant owners troubleshoot and manage their plants," he said. 
“And in 2016 I completed the purchase of my own 162-acre arable farm. This was around the same time two years’ worth of planning came off for the development of my own AD plant at Batchacre Hall Farm, Staffordshire.". 
“I’m really looking forward to the future – AD is an exciting area to be involved in and I encourage anyone looking to diversify to consider it.”

IADAB News Weekly - Edition 1 Announcing Our New Anaerobic Digestion & Biogas Weekly Newsletter

Date: 21 September 2017

The IPPTS Anaerobic Digestion and Biogas News WEEKLY

It’s Thursday the 21st of June, and this is our very first issue of IADAB News Weekly, Edition 1! 

We will now be providing this news digest every week. Watch our intro email, and then read on because the full article is available below this video:





It's free, and our mission is to bring you the latest AD and Biogas news in a concise form

We aim to keep all our subscribers informed of the latest developments in the anaerobic digestion and biogas industry in the UK and globally. 

In today’s news we have a new planning application announced for a biogas plant to be built on a brownfield site in Sheffield which seems to tick all the boxes for sustainability. 

We can say that because we are told that the feedstock will be food-waste, and that the biogas will be upgraded to biomethane.

We also assume that the high efficiency plant will be one of the current breed of the most efficient type of AD energy uses, that being direct injection into the gas grid.

The developers of the Beeley AD Plant, will no doubt be be relieved, by the UK Department for Transport's (DfT's) response to its consultation on the Renewable Transport Fuel Obligation (RTFO) which we cover in our second featured article.

In our final excerpt, we report on an academic investigation in progress on the anaerobic co-digestion of food waste with sewage sludge

We do so, because we like to emphasise that Anaerobic Digestion is still a young discipline and that the technology is likely to develop much higher process efficiencies through research of this type.

Those stories are coming up right here...

Anaerobic Digestion Plant Planned for Beeley Wood

Plans have been submitted to develop an anaerobic digestion plant at the Beeley Wood Sustainable Business Park in Sheffield to replace a WWII-era factory and generate enough gas to power 2,500 homes.

Plans put together by Pegasus Group on behalf of Beeley Wood Biogas Ltd detail have been submitted to Sheffield City Council to redevelop the land bordering Beeley Wood in the Don Valley.

The site was formerly used by Union Carbide in the aftermath of World War II to produce carbon electrodes for the steel industry, graphite rods for the nuclear industry and related industrial products.

The new plant would receive commercial waste that has been accepted and de-packaged at the adjacent Waste Recycling and Destruction Ltd food recycling centre. via Anaerobic digestion plant planned for Beeley Wood

Anaerobic Digestion and Bioresources Association - Biomethane perfectly positioned to meet new renewable fuel targets

The UK's trade body for anaerobic digestion (AD) has welcomed the Department for Transport's (DfT's) response to its consultation on the Renewable Transport Fuel Obligation (RTFO), declaring biomethane to be perfectly positioned' to meet increased targets for renewable fuels.

DfT's reforms will obligate fuel suppliers to provide 9.75% of all fuels from renewable sources by 2020, a doubling of the current 4.75% obligation that will then rise to 12.4% of all fuels by 2032, helping to align the RTFO with the Government's Carbon Budgets. 

Biomethane produced through the recycling of organic wastes and energy crops is one such fuel derived from renewable sources that can help fuel suppliers to meet this new higher target, particularly for heavier vehicles for which electrification is impractical or expensive.

With more than 80 AD plants across the UK already producing biomethane, the UK AD industry has sufficient capacity today to produce enough biomethane to power 80% of the UK's entire bus fleet and the potential to produce enough biomethane to power 75% of all HGVs in the UK. It can also be used directly on farms to fuel agricultural vehicles.

Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association (ADBA), said of DfT's response to the RTFO consultation:

ADBA greatly welcomes DfT's increased commitment to supporting low-carbon fuels, which are essential for decarbonising the UK's emissions-heavy transport sector and meeting our Carbon Budgets.

The rising of the obligation for renewable-sourced fuels to 12.4% by 2032 goes beyond what was originally consulted on and will create a positive investment environment for renewable fuels. As a low-carbon, low-cost, and technology-ready transport fuel that can deliver £2.1 bn in CO2e savings per year and dramatically improve air quality, biomethane is perfectly positioned to play a leading role in helping fuel suppliers to meet these increased targets.

This news represents a huge opportunity for biomethane and will give plenty of food for thought and discussion at the ADBA Biomethane & Gas Vehicle Conference taking place in Leeds the week after next. via Anaerobic Digestion and Bioresources Association - Biomethane perfectly positioned to meet new renewable fuel targets – ADBA

Investigation on the anaerobic co-digestion of food waste with sewage sludge

In this laboratory-scale investigation on the applicability of the co-digestion of food waste with sewage sludge, evaluated were the effects of the single-stage versus two-stage operating modes at the hydraulic retention time (HRT) of 15 days, and the impact of HRTs: 15 days vs. 25 days, on the single-stage operation. via Investigation on the anaerobic co-digestion of food waste with sewage sludge.

We anticipate that our readers, just like ADBA will welcome the UK's DfT's increased support for low-carbon fuels, and in other nations globally this news will perhaps help to reinforce UK government statements that the UK will continue to support its decarbonisation commitments.

5 Ways in Which Biogas Can Reduce Urban Air Pollution



This short video explains how biogas can reduce urban air pollution.



1- Gas powered vehicles emit far lower Nitogen Oxides, known as NOx, and particulate matter than their diesel-based counterparts.By transPublish Postitioning away from petrol and diesel fuels to biomethane, cities can achieve both GHG emissions reduction and improved air quality.This has already been done successfully for some vehicle fleets in some cities including Lille and Berlin.



2. Replacing other fuels with biogas use can reduce Fine Particulate Matter in urban air in developing countries. Over 30% of fine particulate matter in the urban air in Central and Eastern Europe and Africa originates from domestic burning of solid fuel such as wood and coal for heat and cooking.



3. Replacing wood with biogas as domestic fuel would almost eliminate particulate matter emissions from this source.


4. Replacing coal with biogas for electricity production would nearly eliminate particulate matter emissions and reduce carbon dioxide emissions by over 40%.



5. Diverting organic waste away from landfills may improve air quality around the landfill, and in particular can reduce odours.

6. By collecting and using food waste, or the organic fraction of municipal solid waste, for the production of biogas energy, cities can improve air quality.This is because biogas plants not only generate their own renewable power via biogas, but can also be used to dispose of the waste, which will no longer be sent to landfills.
