Technical options to reduce metha

• Separate POME solids, treat separately

• Flocculation / filtration / flotation / centrifugation • Aerobic treatment for residual waste water / recy

• Oily sludge can be used as feedstock, fuel, or co• Solids in POME: 0,5% oil, 0,7% protein, 1% fiber

• Compost POME solids with EFB

• Good recycle of nutrients• Interesting to producers today: savings in artificia

• Low to medium investment cost• Many CDM projects, AVC technology in most of t

• Conditions at mill site select technology

• Capture methane and use as energy in own mill 

• Releases more solid biofuels (shells and fibres) fo

• Sell electricity to national grid, where there is one

Methane capture, use as energy or fla

• Membrane covering of anaerobic ponds

• Can be applied on existing open ponds

• Medium investment cost• Accidental fire reported

• Anaerobic tank reactors

• Compact equipment• Higher reaction rate, better control• High investment cost• Corrosion problems reported

• Make biogas of POME solids

• Separate POME solids first by filtration, flotation etc• Anaerobic degradation in a closed bioreactor

• Use biogas to produce energy• Collect filtrating waste water and process aerobicall
