GENeco aims to become carbon neutral and zero waste by 2020. It operates 11 liquid waste treatment centers in southwest England that process over 1 million cubic meters of sewage sludge annually from more than 1 million people, as well as 35,000 tons of food waste and 20,000 tons of grit and screenings. The waste is treated through various processes to produce 250,000 tons of biosolids per year for agricultural use, 35 gigawatt hours of renewable energy, and 80 gigawatt hours of biomethane gas injected into local gas networks, displacing over 30,000 tons of carbon emissions. GENeco also partners with companies like Unilever to supply biomethane and uses biomethane

Liquid organic waste
• Since 2010 EA regulations mean liquid waste can
no longer be accepted by landfill sites
• Types of liquid waste GENeco can accept are
landfill leachate, farm waste, hygiene and cleaning
wastes
• GENeco has 11 liquid waste treatment centres in
the south-west which all accept domestic waste
What is it?

What happens to it?
Organic waste
• Zero waste to landfill process
• Primary treatment  Biological
treatment  Anaerobic digestion 
Closing the loop
• Real-time monitoring throughout the
whole process allows optimum
efficiency and cost

8. 8
Gas to grid
• In 2016 we injected 8.1M m3 of
biomethane to the local network
• This is enough gas to power over
5,000 homes
• It equates to a total CO2e
displacement compared to
combustion of natural gas of over
30,000 tonnes
Renewable gas generation
CO2
displaced
= 8,300

Sludge recycling
• 250,000 t/year of biosolids spread to
agricultural land
• GENeco now a recognised
biofertiliser supplier
• £1M income per annum
Nutrients to agriculture

GENeco and Unilever
• Deal signed to help the consumer goods
company become carbon positive by
2030
• Committed to use biomethane at five of
its sites in the UK
• Supplying them with 10GWh/a through
green gas certificates
Green gas partnership

Biomethane in transport
• First bus in the UK to be powered by
human and food waste
• Initially trialled on Bath - Bristol
Airport route
• Year long operation on First Bus
route "number 2"

Outreach programmes
• Our most recent outreach programme involved Bristol
students raising awareness about food waste recycling
• Local media organisation Boomsatsuma created a
series of short films as part of Bristol Learning City
initiative
• Enabled students to gain experience in how the creative
sector operates in a commercial environment
