From the experiences of mandatory separation (MS) implementation has been demonstrated that may effectively reduce the generation of municipal solid waste (MSW) and increase recycling rate. It’s also proved as a critical mechanism in achieving recyclable recycling channel and well-developed recycling industry. Thus, part local municipalities in Taiwan have introduced mandatory separation into waste management policy voluntarily and the results are highly accepted by most local waste management department and the public whom involved. However, the cost-benefit analysis of recyclables collection/treatment system of 17 local representative municipalities in Taiwan shows negative except Tainan city, Chiayi city , Sinjhuang city of Taipei country and Taitung city. As an important step stone in fostering sustainable recycling industry, optimal operation evaluation and performance efficiency promotion should be taken immediately in further mandatory separation implementation process. Moreover, the capacity analysis under on-site investigation of exist Material Recovery Facilities (MRFs) of recyclable and organic waste demonstrates that should be able to meet the requirement of increasing recyclable and organic waste after mandatory separation policy is enforced. However, the occupational safety and environmental prevention is extensively ignored by most exist MRFs’ managers and on-line operators. Further assistance and management consultant service for these MRFs’ business is strongly recommended which is also frequently requested by MRFs’ operators.
