What is the Difference Between Biomass and Biogas?

The main difference between biomass and biogas is that biomass is a solid material whereas biogas is a gaseous compound created through the process of Anaerobic Digestion.


Biomass typically comes from crop waste, wood and specific resources that have been grown to create biomass energy through burning in the presence of oxygen and Biogas is an end product of the Anaerobic Digestion (AD) process where food waste is transformed into energy in the absence of oxygen as part of the AD process.

Biomass energy is the use of biomass as an energy source. With biomass energy, biomass is burned or converted to make heat, electricity, or liquid fuel.

Biogas is a renewable energy; it is created as a direct result of transforming food waste to energy and it is an environmentally friendly way of doing it.

Anaerobic digestion is a sustainable process involving the breakdown of organic matter within anaerobic digestors through a process which generates biogas energy and fertiliser. 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.

Benefits of AD

  • Turns waste into a resource - energy and fertiliser
  • A natural fuel produced rather than use of fossil fuels
  • It produces a high nutrient fertilizer
  • Reduces a company’s carbon footprint


When it comes to recycling food waste to help generate biogas not only are companies doing their part to reduce the food waste the UK generates on a daily basis, but they also will be reducing their Co2 emissions and these efforts support long-term environmental sustainability. Using the expert knowledge of teams within the food waste recycling industry companies will gain regulatory, commercial and engineering support from the renewables sector.

There are a range of food waste materials that can be recycled as part of the AD process, across several anaerobic digestion plants across the UK, from food waste through to oils and fats.

These businesses 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.
