No matter how hard we try we will always produce waste – and too much of it! There are 3 options for dealing with this waste – bury it in landfill sites (This is becoming more expensive as land prices rise), burn it with the resulting gases being released in the atmosphere (At a cost to us and our planet) or bio digest it through anaerobic digestion (AD) (low cost Rapid ROI and a sellable product is produced through this process)
Anaerobic Digestion is a wonderful biological process in which bacteria, commonly found in soil and deep water, break down organic material in the absence of oxygen, into biogases that can be used to generate energy. The material left at the end of the process (the digestate) exits the container in two forms, a liquid fertilizer and a dry mulch (Much like soil) it is rich in nutrients and is an excellent natural fertilizer.
A single 40ft container can process 500kg of organic material per day and can be increased to up to 6 ton a day with additional digesters ideal for schools, hotels or even small communities to power and heat your life with waste!

The great thing about AD is that the environmental impacts are all positive:
• Produces renewable energy
• Provides a safe sustainable waste management system
• Gives a cleaner environment by reducing pollution and odour
from organic waste
• Reduces the use of artificial fertilizers
• Controls pathogenic bacteria and viruses
• Reduces greenhouse gas emissions
• It’s carbon neutral
• Helps the economic regeneration of rural communities.
Anaerobic digestion has the potential to reduce both emissions to atmosphere, as well as watercourse pollution from run-off, for a wide range of feedstocks which currently cause these environmental problems, of which the largest by volume are agricultural slurries.
In line with the best practice AD plants, slurry is scraped into the digester on a daily basis, so GHG emissions such as carbon dioxide, methane and ammonia are kept to an absolute minimum in order to maximise the biogas potential of the slurry.
Furthermore, if slurries are co-digested with other feedstocks which would normally be sent to landfill or stored/disposed of in such a way as to emit GHGs, AD can successfully capture and utilise this renewable energy.
