About Biogas Renewable Energy

Anaerobic Digesters convert liquid
organic waste into biogas
renewable energy + fertilizer

anaerobic digestion photoAnaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen to produce a combination of methane and carbon dioxide that can be used to generate electricity and heat. The residual digested material is a virtually odour and pathogen free, organic slurry that can be used as an organic soil amendment, an addition to composts, liquid plant nutrients etc.

Agricultural anaerobic digesters are situated on farms to convert livestock manures into biogas. The benefits of agricultural ADs are numerous, and go far beyond the advantages of renewable energy production: farm odours are reduced; bacterial pathogens are reduced; nutrients become more readily available and more predictable to manage; and, digested materials can be recycled as an odour-free crop nutrient.

A key environmental benefit is that the captured methane is converted into electricity, which represents a net greenhouse gas emissions reduction.



Benefits of biogas energy production:

  • Renewable energy production
  • Greenhouse gas reduction
  • Expands organic recycling capacity reducing reliance on landfills
  • Major reduction in odour and pathogens in the digested material
  • Improves wastewater treatment by reducing organic loading at treatment plants
  • Improves groundwater protection by improving the nutrient availability in the digested material
