Sikkim comprises a mix of urban and rural regions, with the top urban areas being Gangtok, Namchi, Rangpo, Singtam, Gyalshing, Mangan, Jorethang, Pakyong, Rhenock, and Melli. Understanding the biomass supply chain in Sikkim is crucial for optimizing the utilization of agri residues and enhancing the region’s bioenergy potential.
Major Crops Grown
| Crop | Production (Million Tons Per Annum) |
| Rice | 0.016 |
| Maize | 0.06 |
The cultivation of these crops results in substantial biomass feedstock, contributing significantly to Sikkim’s bioeconomy.
Residue Generation
| Crop | Residue Parts | Production (Million Tons) |
| Rice | Straw, husk | 0.027 |
| Maize | Cob, husk | 0.02 |
Efficient management of these crop residues is essential for developing a sustainable biomass supply chain in Sikkim.
Significant Regions of Availability
- Rice: East Sikkim, West Sikkim
- Maize: Along Teesta River
Identifying these biomass clusters enables targeted strategies for biomass feedstock collection and utilization.
Utilization of Crop Residues at the Farmer’s Level in Sikkim
- Essential Usage for Fertilizer
Residues of Cardamom, Ginger, Oilseeds, and Rice are primarily utilized for preparing compost fertilizers. - Fuel Usage for Domestic Needs
Residues of Paddy, Rapeseed & Mustard, Soybean, and Wheat are used as fuel for household cooking. - Field Preparation through Residue Burning
Residues of Paddy and Wheat are commonly burned in open fields to prepare the land for subsequent sowing. - Commercial Applications
Farmers generate additional income by selling crop residues to briquetting or biomass plants, creating economic value from agricultural waste.
