Tyres Specifications
WRAP have produced two very valuable specifications applicable to used tyres.
WRAP commissioned the British Standards Institution (BSI) to prepare this Publicly Available Specification, PAS 107, in collaboration with the tyres reprocessing industry. It provides a specification for producing grades of size-reduced tyre rubber of consistent and verifiable quality.
The use of recycled tyre materials in a wide range of civil engineering and industrial materials and applications is well established and has grown considerably in the last decade. This Specification sets out a formal material specification system and defines minimum requirements for the initial storage, production and final storage of size-reduced, tyre derived rubber materials intended for a range of applications in existing and emerging secondary end markets.
The overall aim of the PAS is to provide a specification that can be adopted by suppliers for producing grades of size-reduced tyre rubber such that potential customers will be assured that they are procuring a material of consistent and verifiable quality.
The introduction of PAS 107 harmonizes the various independent specifications across the industry in the UK.

WRAP commissioned the British Standards Institution (BSI) to prepare this Publicly Available Specification, PAS 108, in collaboration with the tyres reprocessing industry. It provides a specification for producing compact tyre bales of a consistent and verifiable quality and dimension.
The compression of these tyres into bales provides a means of reusing these tyres whilst at the same time, reducing the demand for primary aggregate materials in construction.
PAS 108 sets out to provide a specification that can be adopted by suppliers for producing tyre bales such that potential customers will be assured that they are procuring a construction material of consistent and verifiable quality. Thus the core of this document addresses the production, handling, storage, transport and placement of standardized tyre bales, the dimensions and properties of which are described in this PAS. In addition, guidance is given on engineering properties and typical construction applications.
