Abstract: Here is given an estimate of crop residue production and different recycling options as a source of renewable energy. India produces 388 Tg crop residues but only 182 Tg equivalent to 2818 PJ is usable. Recycling as manure can replace 15% of 595 PJ national fertiliser energy. Recycling in digester can produce 20.32 billion m³ biogas. It can be converted into 182 Tg of biocoal generating 156–258.3 billion unit (kWh) electricity. It can lead to 16 billion dm³ ethanol productions. Having less environmental consequences, different recycling options can make the crop residue an environmentally sound sustainable energy system.
Keywords: crop residue; renewable energy; biogas; biocoal; ethanol; India; energy sources; recycling options; sustainable energy; fertiliser; sustainability.
