BACKGROUND

WMRAS is committed to the following objectives for which it was constituted:

The accreditation scheme for Recycled Aggregate Supplier is an industrial led effort initiated by the Waste Management and Recycling Association of Singapore (WMRAS). The scheme is the result of a year long effort by WMRAS and the Recycled Aggregate Suppliers, rigorously soliciting inputs from Industry Professionals, representatives from Statutory Boards and Construction Industry Associations through the BCA-WMRAS working committee on sustainable construction.

The Recycled Aggregate supplies industry has long been 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 the waste processors serving the construction industry. Through the adoption of the testing standards specified in the BS EN12620, the objective is to increase the Industry Professional and Users’ confidence in specifying the use of recycled products in their projects.

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 Processors who are committed to quality, consistency and safety of the production plant and products. The accreditation criterion were jointly developed by the BCA-WMRAS working committee on sustainable construction comprising representatives from SCAL, ACES, IES, Nparks, PUB, HDB, LTA, NEA and BCA.

The scheme is open only to waste processing companies with facilities located within Singapore.

Accreditation Grading and Process

Two categories of accreditation are available:

Class 1 Recycler:         For recycling plants supplying recycled concrete aggregates meeting requirements of SS EN 12620: Specification for Aggregates for Concrete.

Class 2 Recycler:         For recycling plants (including mobile plants) supplying aggregates for general use, such as in road sub-base construction, hardcore for construction use, landscaping etc.

The current scheme aims to accredit recyclers in the Class 1 category based on the criterion listed herein. The criterions and testing requirements were developed in line with the current Standards and Specifications of SS EN 12620. Class 1 recyclers should be capable of supplying recycled aggregates for use in non-structural concrete components and structural usages subject to the approval and guidelines stipulated by the Authorities and Consultant.

The waste processors will be assessed using the accreditation criteria during the accreditation audit, valid for a period of two years. Subsequently, the accredited processors will be assessed annually for compliance in order to retain its grading.
