From organic material to
useful resources.
A proposed continuous bioenergy process combining mechanical feedstock conditioning, mesophilic anaerobic digestion, two-stage membrane gas upgrading, and comprehensive digestate manure recovery.
One input stream. Two high-value outputs.
The proposed Ghitorni facility is engineered for continuous 24/7 operation throughout the year. Every batch of segregated organic waste collected from bulk urban generators undergoes precise pre-treatment before biological conversion into clean energy and soil regenerators.
Organic Resource Recovery Cycle
Collection & Receipt
Segregated kitchen waste, vegetable/fruit scraps, and cattle manure gathered within a 15 km radius from bulk generators (RWAs, hotels, army canteens, institutional kitchens).
• Dedicated segregated intake
Conditioning & Mixing
2nd stage manual and metal detection segregation, heavy-duty waste shredder, and vertical agitator mixing tank blending food waste with carbon sources to maintain ideal C:N ratio and pre-hydrolyzation.
• Hydrolyzation tank balance
Mesophilic Digestion
Biological digestion in two primary digesters (22 m diameter × 9 m cylindrical height; ~3,421 m³ gross volume each). Anaerobic bacteria break down organic solids, producing raw biogas and nutrient slurry.
• Controlled 37°C mesophilic zone
Biogas Upgrading & Grid Injection
Raw biogas passes into two 2,500 m³ gas holders (5,000 m³ total storage). It is then purified through two-stage hollow-fibre membrane gas filters to strip CO2, moisture, and H2S. The resulting biomethane is compressed to meet pipeline standards for household stoves.
Digestate Dewatering & Compost
Digestate slurry from the bottom of the digesters is transferred to a Solid-Liquid Separation (SLS) unit. The dewatered solids are converted into Solid Organic Fertilizer (SOF / vermicompost / aerobic compost), while the liquid fraction is conditioned into Liquid Fermented Organic Manure (LFOM).
Simplified conceptual engineering flow; exact parameters subject to final engineering configuration and regulatory approvals.
Why Food Waste Delivers Superior Biogas Yields
As documented in project research, municipal kitchen food scraps and vegetable market organics have a significantly higher biomethane yield per metric ton than conventional cattle-only dung or crop residues, owing to their high volatile solids content, readily digestible starches, and optimal moisture.
High Caloric Biomethane
Kitchen and restaurant food waste produces up to 3 to 4 times more cubic meters of biogas per wet ton compared to agricultural biomass alone.
Balanced Co-Substrate
Blending kitchen scraps with cattle manure and horticulture waste provides the optimal Carbon-to-Nitrogen (C:N) ratio of 25:1 to 30:1, preventing digester acidification.
Bioactive Digestate
Food waste slurry retains abundant macro- and micronutrients (NPK), making the resulting vermicompost and LFOM exceptionally fertile for organic crop farming.
