Sagamihara Biogas Power Plant Introduction＜Our Activitites＞
Each day at the Sagamihara Biogas Powerfacility, we process 50 tons of liquid foodwaste through methane fermentation
creating an electrical output of528kW (equivalent to approximately 1000households) from our conversion generator.
We then sell the electricity by way of thefeed-in tariff system.
Furthermore, the byproducts resulting
from the fermentation process are used toproduce nutrient rich agriculturalfertilizers.

In collaboration with ourneighboring facility “Japan Food EcologyCenter”, which recycles food waste for thepurpose of producing high quality
livestock feed, we are continuallyextending our cascade recycling* andletting nothing go to waste!
*Cascade recycling refers to our initiative ofselecting the appropriate method of reuse forvarying types of waste material at each stage ofthe production process.

Production of fertilizers

After solid food waste and surplus isdelivered to Japan Food Ecology Center,the material suitable for conversion into
livestock feed is processed as such andsent to contracted pig farmers.
Any unsuitable materials are used formethane fermentation at theneighboring Sagamihara Biogas Powerfacility.

At the Sagamihara Biogas Power facility, the materials
unsuitable for feed production are pumped into digestion
tanks kept at 37-40°C to maintain ideal conditions formethane-producing bacteria. After 60 days of decomposition,
methane gas is extracted and piped into an electric
conversion generator yielding electricity and heat. The heat isused to heat the digestion tanks and for the dehydration ofsludge while the electricity generated is boosted by atransformer and sold.

The byproduct fluids of the methane
fermentation process are collected anddehydrated. Any undecomposedorganic material is separated as sludge
and dried for use as an agricultural
fertilizer while any filtrates extracted
are diluted and discharged into thesewer.
