Anaerobic Digestion

Anaerobic Digestion is a sustainable process of recycling large amounts of food and animal waste which is backed by local, national and government regulated bodies.


How does AD work?

Anaerobic Digestion is a sustainable process of recycling large amounts of food and animal waste which is backed by local, national and government regulated bodies.

For an in-depth description of the process and the types of food and animal waste we can recycle, please get in touch with a member of our team.

Anaerobic digestion is a complex biological process involving the breakdown of organic matter in the absence of air in large, sealed and insulated vessels with controlled heating and mixing.

Food waste enters a sealed building where it is processed into a liquid porridge and then pumped into the anaerobic digestion plant. It is here that bacteria feed on the food waste and produce biogas. Biogas is captured and used as a fuel in CHP engines or sent through a gas filter and sent directly to the gas grid.

The digestate or biofertiliser produced undergoes pasteurisation to ensure that any pathogens are destroyed and is stored in large lagoons ready to be applied twice a year on farmland. The use of this high nutrient biofertiliser replaces the use of fossil-fuel derived fertilisers and ensures a complete loop of carbon and energy capture.

An overview of our process can be seen here.

What are the advantages of AD?

In addition to allowing businesses to consider their environmental impact as a direct result of how they deal with their food or animal waste, they can also reduce their carbon emissions and drive a more sustainable waste disposal process.

Helping a business to understand the long term environmental and economic benefits of food waste recycling is key to our approach.

Just some of the benefits of AD and working with an accredited and approved waste removal business for the environment and businesses are:

  • Environmentally friendly process
  • Renewable form of energy
  • Low cost and high returns for businesses with the ability to save money
  • Adhering to environmental credentials.

You can read more about the benefits of Anaerobic Digestion in our blog ‘What is Anaerobic Digestion

What materials can be included as part of the AD process?

We can accept all types of materials as part of the waste process. We have specific equipment and processes in place to ensure we remove all packaging before it goes into the food waste recycling process.

As a provider of a waste recycling service, we follow the ‘Waste Duty of Care Code’ and ensure we always adhere to the guidelines around the safe removal, processing and recycling of any materials we receive as part of the waste disposal process. We take this responsibility seriously and, where possible, encourage all our customers to consider the packaging they’re including within their waste. We will, however, still remove waste irrespective of the packaging included.

Biomass

Why is biomass considered a renewable resource?

The definition of Biomass is ‘any kind of energy that uses a biological organism (plant or animal) as its source’.

Biomass is typically waste from natural resources such as crop waste and wood. This waste is then burnt through the presence of oxygen to make heat, electricity or liquid fuel. Biomass is an environmentally and sustainable way of generating electricity and is therefore looked upon favourably as a resource for renewable energy.

The increased use of Biomass as a fuel can reduce the dependence on fossil fuels. The benefit is that there is the ability to obtain biomass from natural sources, but it’s important to remember that it can only considered renewable if it comes from a sustainable source.

A large proportion of biomass fuel comes from wood and farmland waste. More and more UK businesses are now finding a way to source their heat or generate heat from sustainable sources such as biomass fuel. The UK as a whole is set to transform the way it consumes energy over the coming years as part of our ongoing battle to reduce our dependency on the likes of fossil fuel energy. Increasing pressures as part of a national agenda mean we’re likely to see higher uptake on these natural, sustainable and environmentally friendly energy sources.

It’s clear that biomass fuel will continue to play an increasingly important part of the way we use energy. But the importance placed on businesses and the UK is to focus on the ever-important circular economy. A push to decrease the gap between the products we make, source and recycle and the ability to generate energy from food waste too will continue to be top of the agenda. For this to work, biomass energy must be from a 100% sustainable source.

Biogas

How do you produce Biogas?

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.

The process of anaerobic digestion to generate biogas is an environmentally friendly and sustainable way of generating energy and capturing electricity and gas as a direct result of the AD process, to be used by local homes and businesses or transferred directly back to the grid.

The process

Food waste enters a sealed building where it is processed into a liquid porridge and then pumped into the anaerobic digestion plant. It is here that bacteria feed on the food waste and produce biogas. Biogas is captured and used as a fuel in CHP engines or sent through a gas filter and sent directly to the gas grid.

The digestate or biofertiliser produced undergoes pasteurisation to ensure that any pathogens are destroyed and is stored in large lagoons ready to be applied twice a year on farmland. The use of this high nutrient biofertiliser replaces the use of fossil-fuel derived fertilisers and ensures a complete loop of carbon and energy capture.

Green energy

What does green energy mean?

Green energy can be made up of a number of different ‘elements’ such as wind, sunshine and wave. Green energy can also be defined as renewable energy since it is not exhausted at the source. It is a sustainable energy that can be used by generations to come.

Green energy is referred to as clean energy due to the lack of negative impacts on the environment; for example, food waste transformed into energy through the Anaerobic Digestion process.

Biogas is also known as green energy as it’s derived from environmentally friendly sources.

When a business chooses to contribute to the waste recycling process by reducing the impact their products have on the environment or by cutting the amount of energy and water the business uses, their actions and the energy directly generated from the waste they recycle play a part in the wider impact this has on the environment. The environmental credentials a business chooses, will have an impact on the way they’re viewed by the local community, competitors and staff.

How can green energy help the environment?

In addition to the benefits of the anaerobic digestion process and its immediate environmental energy benefits, the location of our regional waste management facilities means transportation costs and journeys in terms of miles are also reduced. We have a network of transportation facilities which means we will work out the most economical way of collecting and transporting your business’s waste.

Businesses have a responsibility to ensure they can demonstrate that they are disposing of their waste responsibly and, as part of the process, we will handle the safe transportation, disposal, and recycling of those materials. As part of the waste process we will also provide businesses with a Waste Transfer Note which should be held on record as evidence the business complies with the correct disposal of waste.

Waste

What types of packaging can you accept?

The best way of maintaining a good quality feedstock (food and animal waste) is for our customers to separate packaging from waste at source, but we recognise that this isn’t always possible. At BioteCH4 we have specific equipment and processes in place to ensure we remove all packaging before it goes into the food waste recycling process.

As a provider of a waste recycling service, we have a duty of care to the ‘Waste Duty of Care Code’ to ensure we reuse and recycle the waste we remove as part of the anaerobic digestion process. Any glass, paper and plastics are all removed at the point approved waste enters the building and safely recycled either on site or through our waste recycling partners.

Food Waste

What types of food can you accept?

We can accept all types of food waste. Ultimately the aim of the content of the waste that enters the building is to ensure the ‘perfect mix’ of food to generate the end product – biogas. We can accept anything as part of this ‘mix’ from animal waste, milk, fizzy drinks, fruit and vegetables through to cheese, chocolate and sandwiches.

Under the ‘Waste Duty of Care Code’ it is our responsibility to ensure this waste is removed, processed and recycled in an appropriate manner and when you work with BioteCH4 we are well-placed to provide a truly useful link between the Anaerobic Digestion sector and the food industry, enabling more environmentally and commercially focused processes.
