Feedstock
Feedstock
At the heart of every project lies a sustainable feedstock strategy — the cornerstone of reliability, cost stability, and community value. Our feedstock model transforms Thailand’s vast agricultural potential into renewable energy through structured contracted farming, cooperative logistics, and circular use of agricultural residues.
By securing biomass and biogas feedstock through transparent, long-term agreements, REpoweri ensures energy security for investors, stable income for farmers, and climate resilience for local economies.
Our biomass power plants utilize a diversified mix of non-MSW agricultural feedstocks, including:
Rice straw from irrigated and rainfed paddy fields.
Sugarcane leaves collected after harvest to prevent open burning.
Cassava residues and woodchips from agro-processing industries.
Energy wood species such as Acacia mangium (Kasintapa), Leucaena leucocephala (Kasinnarong), and Eucalyptus, cultivated on dedicated energy plantations.
Feedstock is sourced within a 50–70 km supply radius, ensuring logistical efficiency and minimizing transport emissions. Through contracted farming schemes and community enterprise networks, we guarantee consistent volumes, traceability, and price stability. Each power plant has a long-term feedstock supply agreement (FSA) that de-risks both operational and financial performance.
In addition to fuel supply, agricultural residues are co-processed into compost and biochar, closing the nutrient cycle, improving soil fertility, and generating certified carbon credits.
Our biogas projects use high-yield Napier grass (Pennisetum purpureum) as a base substrate, cultivated on contract-farmed land with guaranteed buyback agreements. Napier grass offers:
High productivity (180–250 tons/ha/year).
Multi-year harvest cycles.
Consistent methane yields (180–220 m³ CH₄/ton dry matter).
Napier feedstock is complemented by livestock manure, food-processing residues, and organic by-products from local industries. This combination maximizes biogas yield and supports methane capture that would otherwise be lost through unmanaged decomposition.
Feedstock logistics are managed through centralized silage hubs, ensuring quality control and continuous year-round supply for fermentation.
After digestion, raw biogas is purified using membrane or PSA upgrading technology to produce biomethane (>96% CH₄). This renewable gas serves as:
A pipeline-quality substitute for natural gas in industrial boilers and furnaces.
Bio-CNG for logistics fleets and local transport.
Bio-LNG for long-haul and maritime use in later phases.
By integrating biomethane production with agricultural and municipal supply chains, RePoweri reduces methane leakage, CO₂ intensity, and import dependence on fossil LNG.
To ensure transparency and compliance with international standards, all feedstock sources are managed under:
Sustainability certification frameworks (ISO 14001, FSC-Energy Crop Certification, or equivalent).
Traceability systems using digital mapping and satellite verification.
Environmental & Social safeguards aligned with IFC and DFI guidelines.
These mechanisms guarantee that feedstock expansion does not cause deforestation, land conflicts, or competition with food crops — instead, it enhances rural livelihoods and circular resource management.
Bankability: Secured feedstock supply agreements (FSA) and diversified crop mix mitigate volume and price risks.
Carbon Impact: Direct avoidance of open-field burning and methane emissions from residues and manure.
Social Co-Benefits: Farmer income uplift, rural employment, and inclusive participation of cooperatives.
Circular Economy: Residue-to-energy-to-fertilizer loops close the material cycle and support long-term soil regeneration.
Our feedstock model converts Thailand’s agricultural base into a national energy backbone:
Contracted farming ensures stability and inclusion.
Residue collection reduces PM 2.5 and open burning.
Fermentation and combustion generate renewable energy.
By-products (compost, biochar, digestate) return nutrients to the soil.
Carbon credits provide verifiable climate finance revenue.
This integrated feedstock ecosystem delivers what we seek most — predictability, sustainability, and measurable climate impact — making every project a model for inclusive, low-carbon rural industrialization.
