Evaluation of Plastic Waste Management in Thailand Using Material ...

C.4 Case study from Sai Mai transfer station
1. General information
Name: Sai Mai transfer station
Address: Sukhapiban 5 Road, Soi. 42, Sai Mai districts in Bangkok
Waste: 2,200 tonnes/day
Waste from Bangkok are transferred to Sai Mai transfer station for temporary disposal by
the collector truck which starts from midnight to avoid traffic jam at peak hours and then
disposed at 6 am or 6 pm to the landfill nearby Bangkok. Figure C-43 shows the
processing of waste collection and storage temporary before transferring to disposal at
landfill site.
This transfer is operated by the oldest system, while the new system is been building
nearby the oldest system. The new system is operated by set the building to cove the
transfer areas in order to protect the contribution of odour problem. Moreover, this new
plant has the wastewater treatment plant. The transfer station is planning to bring in
reverse osmosis plant to treat the leachate, wastewater and water from vehicle washing
with the help of rainwater to dilute the concentration. As the transfer station does not have
any sorting system to segregate recyclable materials from the organic waste, majority of
the non-biodegradable waste such as plastic bags are being transferred over to the landfill.
This has raised a concern as space for landfill is limited due to urbanization. The waste
reduction by recycling the recyclable wastes is promoted instead of allowing it to take up
unnecessary space.
