Background of the Accreditation Scheme

The Accreditation Scheme for Recycled Aggregate Suppliers is an industry-led effort initiated by the Waste Management and Recycling Association of Singapore (WMRAS). The scheme is the result of joint efforts by WMRAS and Recycled Aggregate Suppliers, supported by the BCA-WMRAS Working Committee on Sustainable Construction.

The Recycled Aggregate industry is sometimes confronted with questions on the quality and performance of their recycled products due to a lack of accepted Specification and Standards; and a lack of understanding of the recycling processes involved by industry professionals.

The Scheme aims to improve the quality and consistency of recycled aggregates. Through the adoption of the testing standards specified in the BS EN12620, the objective is to increase confidence in the specification of recycled aggregates for use in concrete production.

This Scheme is managed by WMRAS as part of the effort to promote greater self-regulation by the industry. It also provides recognition to Waste Recyclers who are committed to quality, consistency and safety of the production plant and products. The accreditation criteria were jointly developed by the BCA-WMRAS Working Committee on Sustainable Construction comprising representatives from WMRAS, BCA, HDB, LTA, NEA, NParks, PUB, ACES, IES and SCAL.

The Scheme is open to construction and demolition waste recycling companies with facilities located within Singapore.

Accreditation Approving Committee

An Accreditation Approving Committee chaired by WMRAS and comprising of members from BCA, NEA and LTA will review and recommend the award of Accreditation status to applicants of the scheme.

Accreditation Grading and Process

The Scheme is open to the following:

  • Recycling plants supplying recycled concrete aggregates meeting requirements of SS EN 12620: Specification for Aggregates for Concrete.
  • The criteria and testing requirements were developed in line with the Standards and Specifications of SS EN 12620. Accredited recyclers will be capable of supplying recycled aggregates for use in non-structural concrete components and for structural usages subject to the approval and guidelines stipulated by the Authorities and Consultant.
  • Waste Recyclers are assessed using the accreditation criteria during the accreditation audit, and the accreditation is valid for a period of one year. Subsequently, Recyclers will be assessed annually for compliance in order to retain the attained grading.
