Anaerobic Digestion
Turning organic waste into renewable energy and healthier soils.
Converting Organic Waste into Renewable Energy through Anaerobic Digestion
Organic waste is a valuable resource. Our anaerobic digestion process naturally breaks down food and other organic waste in an oxygen free environment to produce biomethane and nutrient rich biofertiliser.
The process is designed to handle a wide range of organic waste streams including food waste, kitchen waste and other biodegradable materials. Modern pre treatment and processing systems ensure optimal performance, higher biomethane yields and stable operations. By diverting organic waste from landfills, we reduce methane emissions, recover valuable energy and create a cleaner and more circular waste management system.
A Natural and Circular Process Powering Energy and Enriching Soil
Anaerobic digestion mimics a natural process where microorganisms break down organic matter in four stages, hydrolysis, acidogenesis, acetogenesis and methanogenesis. This produces biomethane, a renewable and clean energy source that can be used for electricity, heat or cooking fuel.
The remaining material is converted into high quality biofertiliser rich in essential nutrients. This natural fertiliser improves soil health, enhances crop yields and supports sustainable agriculture. By closing the loop, we create value from organic waste, reduce dependence on fossil fuels and contribute to a healthier environment.
How the Biology Works
Anaerobic digestion is a natural process carried out by microorganisms in the absence of oxygen. These microbes break down organic material and convert it into biomethane and nutrient rich biofertiliser.
Hydrolysis
Complex organic materials such as food waste are broken down into simpler, soluble compounds like sugars, proteins and fats.
Acidogenesis
Microorganisms convert these simple compounds into volatile fatty acids, ammonia and other intermediate products.
Acetogenesis
Further bacteria convert these intermediate products into acetate, hydrogen and carbon dioxide.
Methanogenesis
Specialised microorganisms convert these compounds into biomethane, a clean renewable gas, which is captured from the digester.
How we transform organic waste
Anaerobic digestion turns your organic waste into renewable energy and biofertiliser. Here is what happens at every stage, from the moment the waste arrives at our facility to the point nutrients go back into the soil.
Organic Waste Arrives
Your organic waste is collected and delivered to our facility where each load is weighed, recorded and visually checked. Only suitable organic material is accepted and we maintain full traceability from the moment it arrives on site.
Preparing the Feedstock
Any non organic material such as plastics, metals or packaging is removed. The organic waste is then shredded and blended to create a uniform feedstock. The material is mixed with water if required to achieve the right consistency for efficient digestion.
Pasteurisation
The prepared feedstock is heated to a controlled temperature for a set period to remove harmful pathogens. This ensures the process is safe, compliant and suitable for the production of biofertiliser.
Mix Tank
The pasteurised material is transferred to a mixing tank where it is blended to maintain a consistent composition. This ensures steady feeding of the digesters and helps the process run smoothly and efficiently.
The Digestion Stage
The feedstock is pumped into sealed anaerobic digesters where naturally occurring microorganisms break it down in the absence of oxygen. This produces biomethane and a nutrient rich liquid digestate. The process is continuously monitored to maintain stable and optimal operating conditions.
Biomethane into Energy
The biomethane captured during digestion is cleaned and upgraded for use as a renewable energy source. It can be used for electricity generation, heat or cooking fuel, or upgraded to bio CNG for use in vehicles and industrial applications, reducing dependence on fossil fuels.
Creating Biofertiliser
The remaining digestate is separated and tested to ensure quality and safety. This nutrient rich biofertiliser contains essential nitrogen, phosphorus and potassium and can be applied to agricultural land to improve soil health and support sustainable food production.
Closed Loop System
Every stage of the process is managed and monitored by our team, from waste collection to energy production and nutrient recovery. This closed loop system ensures your organic waste is diverted from landfill and transformed into clean energy and biofertiliser, creating real environmental and economic value.
