Crop-waste conversion


Thermally accelerated Anaerobic Digestion (TAD) is a system that converts organic waste into high energy fuels, such as bio-hydrogen and biomethane, achieving up to 50% biomass to fuel conversion efficiency.

According to one team behind this innovative technology, Biezel Green Energy, this energy conversion yield is significantly better than any current biomass gasification and digestion technique. The company was founded in 2018 by Dr. Preetam Singh in Uttar Pradesh, India. He works alongside co-founder, Dr. Konda Shiva, and is mentored by Professor John B. Goodenough, the inventor of the current generation of rechargeable Li-ion batteries and recipient of the Nobel prize in chemistry 2019 for his work in that field.

“TAD reactors can process any kind of biomass and biomass wastes,” says Dr. Singh. “However, green ligneous wastes, such as banana leaves, rubber plantation waste, palm fronds and coconut husks are preferred.” Rice husks, wheat straw, sugar cane, flowers and ligneous paper waste are also highly suitable. These feedstocks are ideal because the lignin has high hydrogen to carbon ratio in the natural molecules and they respond well to the chemical processes and catalyst that are used in the TAD reactor.
