A landfill gas train for engines with an enclosed standby flare, and the monitoring needed to claim carbon credits under CDM rules.
Organics Articles
Organics Group has spent more than thirty years turning ammonia-laden wastewater, landfill gas, organic and food waste, palm oil mill effluent into revenue with biogas flaring technology deployed on over 300 projects worldwide, commissioned across Europe, Asia, the USA and Oceania. This collection brings that work out of the project archive written for the engineers, regulators and operators who decide which technologies is going to solve their problems.
