ClimeCo International's (CCI) projects are based on Advanced+ Anaerobic Digestion (A+AD) of organic waste streams to produce BioGas.

Anaerobic Digestion (AD) is a

  • Natural fermentation process in which
  • Bacteria consume organics (POME, animal manure, etc)
  • In the absence of oxygen and
  • Release BioGas as a by-product

BioGas is a combustible gas mixture (60% methane/Natural Gas, 35% CO2) with an energy potential of 6kWh/m3 (2.4 kWhe/m3).

Advanced AD: Optimized environment for bacteria

  • Temperature: 30°C to 37°C
  • Good exposure of bacteria to organics (continuous mixing)
  • Continuous & homogenous supply of fresh organics
  • Seperate process stages optimized for each bacteria type
  • Sufficient retention time (volume) for the digestion process

Advanced AD produces significantly more BioGas in less time.

BioGas Production: 4 stages with different, specialized bacteria

1. Hydrolisis Complex organics to sugars
2. Acidogenesis Sugars to simple molecules
3. Acetogenesis Simple molecules to acids
4. Methanogenesis Acids to BioGas (methane & CO2)

CCI A+ BioGas: Industry leading 28m3 of BioGas per TFF

The optimized, multi-stage design of CCI's A+ BioGas Production plants results in the highest BioGas production rate in the palm industry in Latin America: CCI's A+ BioGas Production plants generate on average 28m3 of BioGas per ton of fresh palm oil fruit (TFF), 30% more than standard covered lagoon systems.

Proven Technology for over 40 Years

Anaerobic digestion is a proven technology, operated with huge commercial success in Europe & SE Asia for over 40 years.

Germany alone operates 8,000 BioGas-to-power systems over 500kWe, with a combined capacity of 4,000 MWe.

Following a strong growth since 2009, Europe now operates more than 17,000 commercial BioGas plants (capacity>500 kWe).
