Problems with Medium-scale commercial AD

Medium-scale Biotech system

Existing medium-scale commercial biogas systems

♲   Biotech Ltd in Kerala

>   Used in local markets and
      companies that supply food

♲   Nisagruna system developed by BARC

>   Pilot project built in Mumbai

Both systems use two-stage digestion, BUT
both are too expensive, not economic for business

Possibilities for Medium-scale AD

• ♲   Need for low-cost medium-scale AD sytsem
• ♲   Technicians available from small=-scale programs
• ♲   Very poor need employment
• ♲   Government and UN very keen

A low-cost medium-scale digester is under design
It uses two stage digestion, but should be low-cost

It needs to be costed, investment funding is required
and a keen entrepreneur should take it forward
