July 13- A technical visit to Integrated Recycling Facility (IRF) Alam Flora Environmental Solutions Sdn Bhd in Putrajaya was performed by a group of researchers from Laboratory of Processing and Product Development. This visit was led by Assoc. Prof. Dr. Mohd Rafein Zakaria together with Assoc. Prof. Dr. Mohd Noriznan Mokhtar and Dr. Halimatun Saadiah Hafid to visualise the pilot-scale anaerobic digester facility including the operational part and technology process of biogas production using domestic waste collected from Putrajaya municipality. During the visit, a briefing on the overall process flow starting from the waste collection, sorting, and processing was given by the IRF Executive Officer, Mr. Muhammad Amin Asyraf.

In summary, IRF anaerobic digester facility was operated at 500 kg waste / day capacity and can produce 35 m³ of biogas with 55% of methane content. This facility generated 40 kW/h of electricity which could be used to operate the internal facility (conveyer belts) for 4 hours of consumption. Waste that has been digested exits the biogas system in the form of organic fertiliser. The discussion has concluded with potential collaboration on research involving the integrated biogas production and composting system. The integrated system will generate electricity and this strategy will simultaneously reduce the greenhouse gas emission and potential of river water pollution attributed from the leachate generation from the organic waste.

Visit to Integrated Recycling Facility (IRF) in Putrajaya and discussion between researchers from Laboratory of PPD and IRF officer on the pilot scale anaerobic digester processing for biogas production from municipal solid waste.
