SAFE AND ENVIRONMENTALLY-FRIENDLY ON-SITE INDUSTRIAL AND COMMERCIAL SOLID WASTE (ICW) TREATMENT SOLUTION

Today, waste is generally transported to incineration plants and processed to reduce solid waste volume by about 90%. The ash output is subsequently disposed to Pulau Semakau as a landfill, which will run out of space by 2035 at the current waste disposal rate. The transportation of waste also generates carbon footprint and contributes to climate change.

JTC is seeking safe and environmental-friendly on-site industrial and commercial solid waste (ICW) treatment solutions with solid output no more than 5% of the original input by weight. The by-product solid output should meet regulatory standards for use in the building and infrastructure domains. In addition, there could be opportunities to recover energy for generation of utilities e.g. electricity, hot water, etc. at the building. The waste streams to treat are mainly mixed waste generated from the manufacturing processes, packaging, cafeteria, etc. Preferably, the solution can demonstrate the ease to scale up daily treatment of ICW generated beyond building-level.

The solution should bring down the overall operations and maintenance costs of waste management. Savings from refuse disposal (at benchmark rate of $77/ton), operating costs (e.g. rental of compactors, transportation of waste) and utilities generated on-site could be used to offset the costs of deploying and operating the solution.

• As this is an on-site waste treatment solution, it should meet regulatory standards with minimal odours and noise for occupants’ comfort.
• Solution should not require additional Gross Floor Area (GFA) for implementation.
• Solution should work within current electrical loading i.e. 32 Amps 3-Phase, for industrial estates.
• Solution is preferably at prototype/minimum viable product (MVP) phase with demonstrated technology for waste treatment and show preliminary commercially viable uses for the by-products (eg. filler materials in the building and infrastructure domains).
• Solution for utility generation (e.g. recovered energy) should be used on site, and demonstrate a pathway for commercial viability.
• Prototype of the solution should have a capacity to treat no less than 2 tonnes of waste within 24 hours; and has potential to scale up daily treatment of waste generated beyond building-level. The eventual scaled solution should strive to overcome NEA’s nuisance buffer stipulated for waste treatment facilities.
• Solution must comply with all relevant safety regulations raised by Ministry of Manpower (MOM) and Singapore Civil Defence Force (SCDF).
• Solution proposed should be above TRL 6.
• Proposals should include information on any proof-of-concept (POC)/MVP that is non-sensitive.
• Applicant should indicate estimated commercial price of solution, cost of operation/maintenance and cost-benefit analysis of the solution in the proposal.

Besides addressing the above requirements, the proposed solution should also fulfil the following criteria:

• Contains novelty in addressing the abovementioned criteria.
• Wherever applicable, aim to:
  • Enhance safety of operations; and/or
  • Reduce reliance of manpower; and/or
  • Achieve cost-effectiveness; and/or
  • Improve efficiency/productivity.

The solution should ideally be deployable immediately as a pilot or with minimal additional development within a timeframe of no more than 20 months.

JTC will provide mentorship and test-bedding site for the solution. Selection of projects and test-bed sites will depend on the availability of the particular wastestream to be reduced in JTC’s industrial estates.
