Making biogas an accessible and reliable investment

Business cases

We make all kinds of biogas applications reliable and profitable

Palm oil company

Organic waste amount (palm oil mill effluent, POME) 200 m3/day
Electricity requirement (currently generated through the use of a diesel generator) 2,000 kWh/day
Current costs for electricity production US$ 243,000/year
POME fed into reactor 100 m3/day
Total reactor size corresponding to the amount of waste/water mix and the retention time 5,000 m3
Investments costs for biogas plant US$ 500,000 (incl. US$ 10,000 for fittings and fixtures and US$ 15,000 for average-cost generator)
Biogas produced 2,100 m3/day, replacing all diesel for electricity production at 70 % generator conversion efficiency
Payback time on investment ~ 1 year (~ 2 years not counting fertilizer savings/earnings)

Calculated for Indonesia.

Cow-breeding farm (3,000 cows)

Organic waste amount (cow dung) 30 tons/day
Electricity requirement (currently generated through the use of a diesel generator) 960 kWh/day
Current costs for electricity production US$ 96,000/year
Water volume requirement for dilution to desired TS (total solid) value 20.16 tons/day
Waste/water mix fed into reactor 33.31 tons/day (of which 13.15 tons organic waste)
Total reactor size corresponding to the amount of waste/water mix and the retention time 1,800 m3
Investments costs for biogas plant US$ 200,000 (incl. US$ 10,000 for fittings and fixtures and around US$ 10,000 for average-cost generator)
Biogas produced 986 m3/day, replacing all diesel for electricity production at 70 % generator conversion efficiency
Additional realizable revenue from sale of process leftover, a high-grade organic fertilizer 1 ton of dry fertilizer/day → US$ 90,000 /year if calculated at US$ 25 cents/kg
Payback time on investment ~ 1 year (~ 2 years not counting fertilizer savings/earnings)

Calculated for Indonesia.

Large food canteen at sugar industry (serving ~500 people/day)

business-case-large-food-canteen-fov-biogas

Organic waste amount 1 ton press mud/day + 25 kg food waste/day
Current energy use (LPG) 612 cylinders (19 kg type)/year
Current energy costs US$ 16,524/year
Water volume requirement for dilution to desired TS (total solid) value 1-1.5 ton/day
Waste/water mix fed into reactor 2-2.5 tons/day (of which ~ 1 ton organic waste)
Total reactor size corresponding to replace ~ 77 % of LPG use 100 m3/day
Other investments needed 5,000 L storage tank, in order to store the waste along with the processed water. It can also help to feed the digester, during holidays as a reserve. A mixer should be used to ensure uniformity of the waste.
Biogas produced 75 m3/day (would replace ~ 77 % of LPG use)
Resulting energy cost savings US$ 12,724/year
Payback time on investment Maximum 2 years (with operation costs considered)

Calculated for India.

Small food canteen

business-case-small-food-canteen-fov-biogas

Organic waste amount (food waste) 50 kg/day
Current energy use (LPG) 420 cylinders (19 kg type)/year
Current energy costs US$ 11,340/year
Water volume requirement for dilution to desired TS (total solid) value 0.5 tons/day
Waste/water mix fed into reactor 1-1.5 tons/day (of which 0.5-1 ton organic waste)
Total reactor size corresponding to replace ~ 77 % of LPG use 30 m3/day
Other investments needed 3,000 L storage tank, in order to store the waste along with the processed water. It can also help to feed the digester, during holidays as a reserve. A mixer should be used to ensure uniformity of the waste.
Biogas produced 40 m3/day (would replace ~ 77 % of LPG use)
Resulting energy cost savings US$ 8,775/year
Payback time on investment Maximum 2 years (with operation costs considered)

Calculated for India.

Small urban farmer

The customer generates 200 kilogram of cow dung per day. We installeded a 10 m3 biogas plant to replace LPG usage.
