HI,
For Palm Oil Mill Effluent.
We are active in S.E.Asia, producing biogas from biological wastes.
We have an office in Jakarta and have several ongoing projects to produce
biogas and then electricity via gen sets. Further, we take the Empty Fruit
Bunches and gasify them for plenty more of electric power.
Our main Business Development office in Bangkok: Mr. Krishna Tiwary,
krishna.tiwary at asiabiogas.com; ph: +66 081 987 8670.
Currently, I look after the technology section. Through the company's life,
there have been some good, eminent people working here. I think you will
receive reasonable advice from Mr. Tiwary or else he will forward the
questions.
Regards,
Aloke Vaid
