ADBA Press Release:
United Kingdom AD Industry Responds to CCC Net Zero Report
Responding to the publication of the Committee on Climate Change's (CCC's) new report calling for the UK to set a net-zero target for 2050, Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association
"The UK's anaerobic digestion (AD) industry fully supports the Committee on Climate Change's call for net zero emissions by 2050, which is a vital target to ensure we avoid the worst effects of climate change.
"By converting organic wastes and crops into renewable heat and power, clean transport fuel, and soil-restoring natural fertiliser, AD has already reduced the UK's greenhouse gas emissions by 1% and has the potential to reduce them by as much as 5% if the industry meets its full potential. Crucially, AD reduces emissions from hard-to-decarbonise sectors such as heat, transport, and agriculture, as well as from the power sector and from waste.
"As a technology-ready solution that can tackle climate change right across the economy, it's vital that government recognises and rewards the many benefits of AD so it can make the maximum contribution to decarbonisation at speed and scale.
"We therefore also support the CCC's call for a new regulatory and support framework for low-carbon heating (where biomethane from AD can make an important contribution) to address the current million-pound funding gap."
Reactions Across the Web to the CCC Net Zero Report
There has been a welcome response from numerous groups to the CCC’s report with the top line call for the immediate enshrining into law of a national net zero by 2050 target to be put forward by the government.
However, the report does also note that some home nations are currently better equipped to deliver more rapid decarbonisation than others. Scotland, for example, is encouraged by the CCC to target net-zero emissions by 2045 – due to a greater potential to depollute its economy compared to the rest of the UK – whereas Wales should target a 95% reduction in emissions by 2050 (from the same 1990 baseline).

Renewable Energy CfD Scheme Call
Small-Scale UK Renewable Energy CfD Scheme Called for.On the day that the UK didn’t leave Europe, trade association ADBA called for a Contracts for Difference (CfD) scheme for Small-scale Renewable Energy including biogas.
ADBA also calls for AD not to be excluded from future CfD auctions.
The trade body for the UK’s anaerobic digestion industry calls on the government to introduce a bespoke low-carbon Contracts for Difference scheme to support small-scale renewable technologies.
ADBA did this on 29 March 2019, the day the Feed-In Tariff subsidy was ended by the UK government.
AD plants generate renewable electricity, heat, and natural fertilizer by treating organic wastes and energy crops. They also offer a range of other benefits including greenhouse gas mitigation from avoided waste emissions, income diversification for farmers, and energy and fertilizer supply security.
The UK’s AD industry currently has capacity to power 1.2 million households, offering flexible, baseload power, but has the potential to generate far more, with the right support.
“Beyond this levelling of the playing field with the big generators, they are calling on government to develop a bespoke, small-scale, low-carbon CfD auction mechanism to encourage competition in the small-scale sector and recognize the additionality that AD can provide in the form of greenhouse gas mitigation, agricultural diversification, and energy and food security.

Recently we wrote a report about the state of anaerobic digestion plant and biogas development in India. We noted that at national government level there was very little indication of any top-level awareness of the great potential for the betterment in India, available from biogas technology.
We said that this was disappointing because once India led in biogas. The was a growing number of small rural biogas plants and its production was having many spin-off advantages.
The same is not true in some parts of India where a number of people are developing their own biogas plant systems and helping those around them to join in with the advantages of anaerobic digestion. This, we think you will agree is amply demonstrated in the following article extracts:
1 - Jharkhand Man Installs Biogas Plant in Balcony, Slashes LPG Bill by Half!
Able to serve a family for four years, the entire portable structure cost him less than Rs 10,000 and took a few hours to assemble. No wonder he is the talk of his neighbourhood now!
Almost 160 years ago, the first successful biogas generation plant was established in Mumbai, India. Since then, approximately five million biogas plants cater to domestic needs like water heating and cooking.
Contrary to this, various countries, especially Germany, have been efficiently harnessing its benefits in other sectors.
“Having been the forerunners, we should have led ahead of all in ushering the biogas revolution, not the European countries like Germany, that have become forerunners of biogas utilisation, both in domestic and public spheres,” said a senior corporate executive, while speaking to The Better India.
Based in Jamshedpur, this executive, Gaurav Anand, has led the movement by becoming the first man in the steel city to build a biogas plant small enough to fit into his apartment’s balcony!

2 - Patna Girl Builds Biogas Plants, Provides Electricity to Poor Farmers!
City born and bred she may be, yet Akansha Singh was aware of the economic and social inequalities that exist within India. But it wasn’t until she got to the ground and observed first-hand did she realise the scale of the issue.
After completing her Masters in Social Entrepreneurship from the Tata Institute of Social Sciences (TISS) in 2014, Akansha had set out to Jhabua district in Madhya Pradesh as part of an internship.
She was 24 at the time.
“That was a devastating eye-opener for me. The two weeks that I was there, I observed no households had toilets neither did they have any proper power supply. Which meant, the women had to cook food before nightfall as their farmer husbands finished their farming activities by that time. One thing that had particularly affected me was that these families consumed their meals cold because they had to finish preparing dinner while there was still natural light,” says Akansha to The Better India.
During this period, she noticed many social and environmental issues in the region. The women were still cooking using cow dung cakes, and the entire family was inhaling hazardous smoke regularly.
Finally, after months of convincing and explaining to them the many benefits of the project, the villagers yielded, and Akansha began looking for land to build the plant.
“Fortunately, a person from another community volunteered and donated a patch of land for the project. It is remarkable as caste system is much prevalent in the region, but this kind individual wanted the underprivileged community to lead better and empowered lives. From there, our journey started,” she says.
Today, they have two biogas plants in Samastipur; one with 2-hour bioelectricity capacity while the other supplies power for four hours.
Swayambhu received its initial funding from DBS Bank, Singapore. Her project was also aided partly by the beneficiaries and mostly by both government and non-government agencies.
“There has been a visible change in these areas. After seeing how electricity has brightened up their lives, the beneficiaries have become truly committed to the cause and pay charges without fail. Also, ever since they have ditched chemical pesticides and fertilisers for the organic manure from the plant, they have been saving a considerable amount of money as well as observed better yield. Our solution has impacted in multiple folds,”
In addition to community biogas plants, they have also worked on individual plants for bioelectricity, including one in collaboration with students of IIT Patna.
A Biogas Startup By An IIT-Bombay Alumnus Aims To Fight Air Pollution And Manage Waste
New Delhi: 34-year-old Priyadarshan Sahasrabuddhe, a Pune based engineer is trying to provide a solution for two of the biggest environmental problems facing India – air pollution and burgeoning waste pile ups.
The IIT-Bombay alumnus has launched a technology to produce cooking gas fuel by repurposing the organic-waste produced in the kitchen and at the same time reducing the dependence on fossil fuels. In 2017 he created ‘Vaayu’, a biofuel plant that can be easily installed at homes to convert carbohydrates from organic waste into methane gas which can be used for cooking and heating purposes.
“I was working at my parent’s firm about two years ago and I noticed that every day after lunch, a lot of leftover food used to end up in the garbage bins. Watching all that food go waste, I thought of trying composting to manage that waste. But it was not enough. On researching more, I came to know about biofuels. I found that not only will it help in managing organic waste, it will also help in reducing our dependence on non-renewable sources like LPG,”
said Mr. Sahasrabuddhe.

“Waste segregation is the key here. Initially, when I started advocating for green living, I used to go to each house in my locality every morning to ask them to segregate their waste. There were days when I myself used to pick organic waste from the nearby garbage dumps. But gradually when my neighbours started to understand ‘Vaayu’, they started segregating and I get almost 8- 10 kgs of organic waste at my doorstep every day,”
said the engineer turned innovator.
After a long period of testing of the device at his home and reducing his dependence on LPG to a significant extent, Mr. Sahasrabuddhe pushed others in his family, neighbours, and friends to start using this innovation. Till date his startup has done 135 installations in Pune, Sangli, Aurangabad, Umarkhed (District Yavatmal), Palghar, Nashik and Hyderabad. These installations together are managing up to two tons of food waste per day and saving about 900 LPG cylinders worth fuel per year.
How Does ‘Vaayu’ Work?
‘Vaayu’ is a domestic bio-gas machine which can be installed in the house, in the gallery, on the terrace or in the garden. The apparatus is fuelled by the waste generated in the kitchen which gets broken down by bacterial action known as Anaerobic Bacterial Digestion. Through this process, the carbon dioxide captured inside the organic waste during photosynthesis is divided into methane gas and liquid. The gas is stored in the balloon kind of a structure called the cylinder which is connected to the stovepipe. The cooking experience is exactly the same as that of a regular LPG or piped CNG (Compressed Natural Gas). The slurry generated in this process is high on nutrients and can be utilised as manure for the plants in the house.
The regular size ‘Vaayu’ has a container of two kg capacity in which the organic waste is put. A single two kg container, ‘Vaayu’ produces 200 litres of biogas within 24 hours which is 40 minutes of cooking gas per day saving up to three LPG cylinders per year. The capacity of the device can be increased by adding the containers.
The device requires cleaning up once in six months. The solid undigested material removed is fibrous and can be taken back to the garden as manure. Currently, the cost of installing ‘Vaayu’ is Rs. 20,000 but the operating cost is zero. There is no need of power to run ‘Vaayu’ as it operates on its own. Mr. Sahasrabuddhe is still working to improve the technology to make if more affordable.
Mr. Sahasrabuddhe has also started an informal community of like-minded nature enthusiasts who come up with innovative solutions and want to share them with others. The community, ‘Vaayu Mitra’, provides biofuel solutions according to the number of people residing in a house and encourage them to adopt a greener lifestyle. He says,
In my society, everyone segregates their own waste now. I and my friends are working also with waste collectors and are training them to operate biogas plants so that they become energy suppliers too. This increased value will help them earn better remuneration. via Waste Warriors

Biogas Equipment, a List of 6 Biogas Analysis and Gas Quality Monitoring Equipment Suppliers
Biogas analysis and maximizing the efficiency of anaerobic digestion plants is gaining more attention, as the anaerobic digestion industry matures.
The highest prices are only available for top quality biogas with a consistently high calorific value after upgrading (purification).
To do that operators need to pay close attention to the quality of the digester off-gas.
Thankfully, robust and low cost biogas analysis sensors are available from a number of manufacturers, for controlling the various biogas quality upgrading processes.
Many devices combine the functions of biogas flow measurement with quality monitoring systems for a wide variety of needs.
We found the following list of suppliers of Gas Analyzers for landfills and the biogas plant sector:
1. GEOTECH Gas Analysers for Landfills and the Biogas Sector.
2. Cameron Instruments – Multitec Biocontrol.
3. Union Instruments – Inca Biogas Analyzers.
4. Wilexa Energy – CSM Continuous Siloxane Monitors for Landfill Biogas.
5. Progeco – Biogas Analysis Equipment.
6. Avensys Solutions – Awiflex Biogas Analyzer.
The need to continuously measure methane (CH4) and carbon dioxide (CO2).
can be joined with a need for analysis of the much lower low percentages of CO, H2S, N2, O2, which can also be found in the biogas composition.
Thankfully, monitoring equipment has been developed to do what is needed.

The most obvious sanitary benefit of installing an anaerobic digester system
is the improvements to toilet facilities in the households
. Throughout China and other developing countries, where no sewer system is in place, toilet facilities are in simple shacks.
The toilet is generally a slot in the floor with either a pit underneath or alternatively a trough running to a storage pit behind the building.
In the case of a pit toilet, the slurry in the pit is often literally moving with insect larvae, and in all cases the toilets are smelly and fly infested. For these reasons, toilets are generally located as far away from the other household buildings as practical.
Watch our video below for a contrasting example of what one biogas plant supplier has achieved in sanitary improvement, using a biogas digester:
Biogas Digester Life Cycle Assessment (LCA)
Life cycle assessment (LCA) is a tool that can be used to compare the environmental impacts of different products throughout their entire life cycle (European Commission, 2010).
The LCA has been used to compare different biogas production technologies (Rehl and Muller, 2011; Poeschl et al., 2012a). Several studies have also focused on technologies for biogas production from manure and different co-substrates for manure (Hamelin et al., 2011; Rehl and Muller, 2011; De Vries et al., 2012; Poeschl et al., 2012a).
However, very few studies have focused on the vast number of small-scale biogas digesters being deployed in developing countries. Only one single study has been identified (Chen et al., 2012) and this study largely ignores the issues of CH4 leakage and release and nutrient recycling.
With the current UK calculating being done on the LCA impact of biogas production, it will soon become be easier to make comparisons with other fuels.
SimGas Biogas Systems
SimGas biogas systems are fully integrated farm solutions designed to reach millions of rural households in developing countries. Our systems enable rural households with livestock to use the manure from their livestock to generate clean fuel for cooking and organic fertiliser.
Digesters are arguably even better, though, when they're in poor or developing countries. According to the Center for Climate and Energy Solutions, small-scale anaerobic digesters like the one Porter and Mazur want to build on Everest are commonly used in rural communities to meet heating and cooking needs. China, for example, has an estimated 8 million anaerobic digesters. Nepal - where the one in question would be built - already has 50,000.
Toilet Facilities in the Households with Biogas Plants
The most obvious sanitary benefit of installing an anaerobic digester system is the improvements to toilet facilities in the households. Throughout China and other developing countries, where no sewer system is in place, toilet facilities are in simple shacks. The toilet is generally a slot in the floor with either a pit underneath or alternatively a trough running to a storage pit behind the building. In the case of a pit toilet, the slurry in the pit is often literally moving with insect larvae, and in all cases the toilets are smelly and fly infested. For these reasons, toilets are generally located as far away from the other household buildings as practical.
Reasons to Try Aquaponics
The world today uses epic amounts of non-renewable resources. as we grow old, our backs tend to give senior citizens trouble. Gardening is hard on the back. Aquaponic systems can be designed to ensure you never have to bend over to plant or harvest. lower cholesterol.
Many organizations and countries around the world are seeking to find new sustainable ways to produce food due to the world food crisis. Hydroponic and aquaponic systems have plenty of benefits for developing countries and make use of he output from digestion, known as digestate.
Unfortunately, the digested may still contain some diseases, especially when the digestate has been output after the source has been recognized as including some animal by-products.
The control of pests and diseases of plants grown in aquaponic systems is a problem since pesticide use is clearly limited by the high sensitivity of water pollution which may be caused by it.
In general, published data indicate that a digestion time of 14 days at 35 C is effective in killing (99.9 per cent die-off rate) the enteric bacterial pathogens and the enteric group of viruses. However, the die-off rate for roundworm (Ascaris lumbricoides) and hookworm (Ancylostoma) is only 90 per cent, which is still high. In this context, biogas production would provide a public health benefit beyond that of any other treatment in managing the rural health environment of developing countries.
Energy Shortages in Developed Countries
Energy shortages in developed countries turned out to have an impact on developing countries such as Indonesia (Simamora, 2006). The declining of the reserve natural energy and the increasing of human needs for living force them to always make effort and innovate to solve their problem.
A Substitute for Fossil Fuel Based Household Energy
Any effort for a renewable substitute for fossil fuel based household energy is by developing biogas that have raw material from cattle manure. The biggest parts of Indonesia are rural area which have source income in form of integrated agriculture product, one of them is cattle, so the developing of Biogas is really potential. So far, Productivity and Socialization of Biogas energy in the countryside have not conferred maximal product outcomes.
Many developing countries, such as Colombia, Ethiopia, Tanzania, Vietnam, Cambodia, have promoted the low-cost biodigester technology
aiming at reducing the production cost by using local materials and simplifying installation and operation (Botero and Preston 1987; Solarte 1995; Chater 1986; Sarwatt et al 1995; Soeurn 1994; Khan 1996).
The model used was a continuous-flow flexible tube biodigester based on the "red mud PVC" (Taiwan) bag design as described by Pound et al (1981) and later simplified by Preston and co-workers first in Ethiopia (Preston unpubl.), Colombia (Botero and Preston 1987) and later in Vietnam (Bui Xuan An et al 1994).
More than 7000 polyethylene biodigesters have been installed in Vietnam, mainly paid for by farmers (Bui Xuan An and Preston 1995).
Developing countries have struggled to supply stable forms of energy to many of their inhabitants.
According to the World Energy Outlook, approximately 80 percent of people without electricity live in rural areas in Sub-Saharan Africa and developing Asia.
With no other alternative for energy, many people already rely on biogas and struggle to efficiently transport and store it. The technology is therefore in a good position to be developed and extended.
