Around 2,200 tonnes of waste  incineration ash and non-incinerable waste (NIW)is sent from Singapore to the Semakau Landfill (SL) daily.

To reduce the disposal of NIW to Semakau Landfill and recover value from the NIW, the National Environment Agency (NEA) has launched the NIW Grant Call (19 March to 30 July 2020) to solicit research and development (R&D) proposal under its  Closing the Waste Loop Initiative.

Managing Calcium Fluoride Sludge

One source of Singapore’s NIW was identified to be calcium fluoride sludge, which is generated from hydrogen fluoride waste water treatment in the semiconductor industry. Managing calcium fluoride sludge has been an issue for the semiconductor industry and the sludge is currently channelled to the landfill as there are no economically viable or innovative solutions to process or repurpose the sludge. Innovation can address this gap.

Enterprise Singapore (ESG) supports open innovation on sustainability. Sustainability can be a good catalyst for new ideas and business opportunities for the semiconductor industry. Reducing the volume of calcium fluoride sludge can whittle down waste disposal costs in the long haul. Repurposing the sludge may reduce raw material costs or even generate revenue from the sale of the sludge. This calls for semiconductor companies to partner solution providers to co-innovate so as to materialise the benefits.

A Collaboration Between ESG and SSIA

Singapore has a vibrant ecosystem of companies that develop, testbed and commercialise solutions to serve our national water needs, and overseas demand. Today, there are more than 25 research institutes and over 200 companies involved in this sector, including project developers, technology providers, engineering, procurement and construction (EPC) players, and consultants.  

As the government agency championing enterprise development ESG drives demand-led open innovation by facilitating partnerships between end-users and local companies to develop solutions. ESG partnered SSIA to engage members to embrace innovation by putting up challenge statements and seek innovative solutions to reduce the NIW generated. 7 end-users and 14 solution providers with relevant capabilities and track record were identified based on the challenge statements.  

Efforts to support innovation continues even during Circuit Breaker through 20 matching sessions facilitated online from April to May 2020. Through such partnerships,  companies would be able to tap a bigger talent pool of ideas and talents across industries and develop solutions quickly. 

Solutions providers too would be able to develop competitive business models based on new products and solutions.
