Inquiring about your anaerobic digestion systems biogas plant project for Fiji. I am specifically looking for a system that can process a significant amount of organic waste, including both food waste and vegetation waste if possible.

The estimated input consists of approximately 50, 000 tons per annum of food waste and 10, 000 tons per annum of green waste. I am interested in understanding whether your systems can handle this type of waste stream and the efficiency with which they can convert this waste into biogas and digestate.

Please provide the following details for your anaerobic digestion systems that are capable of processing these volumes.

Technical Specifications:
Types and sizes of digesters available.
Compatibility with food waste and/or vegetation waste.
Efficiency metrics, including expected biogas yield and quality of digestate.
Pricing Information:
Capital costs including any initial setup and installation fees.
Building costs associated with the digester installation.
Operating and maintenance costs.
Operational Details:
Expected lifespan and durability of the equipment.
Necessary operational staffing and skill levels.
After-sales support and warranties.
Profitability and ROI:
Case studies or examples where similar setups have been profitable.
Any available calculators or tools that could help project the ROI for our specific conditions.
