John Barritt Consultancy publish recycled aggregates guidance
Latest guidance document advises on compliance with customer specifications and aggregates Quality Protocol
TO answer the many questions raised with him over the last two years, John Barritt, former special advisor at WRAP, has produced a downloadable document – ‘Recycled aggregates: Guidance for producers and purchasers’ – to explain the fundamental procedures that must be in place to ensure that recycled aggregates meet customer specifications and have ceased to be waste.
Recycled aggregates are widely used in UK construction projects. The quality of these aggregates varies depending on the quality management systems employed by different materials producers. Suppliers operating to technically robust systems can demonstrate that their products meet their customers’ specifications, as well as the ‘end of waste’ criteria set by environmental regulators.
Unfortunately, not all producers have adequate systems in place and, as such, their products are likely to remain waste and not comply with customer specifications.
The guidance document from John Barritt Consultancy highlights the key elements required within a technically robust quality management system and includes a useful checklist.
Issues addressed within the guidance include:
- Where do the rules for producing construction aggregates come from?
- What are examples of the sort of things set within aggregates standards?
- How are testing frequencies set within the standards?
- Which are the harmonized aggregates product standards?
- How does a producer demonstrate that an aggregate product is suitable for a specific application?
- What is required to demonstrate ‘end of waste’ so that a recycled aggregate may be sold as a non-waste product in the same way as a natural aggregate?
- How does the Quality Protocol for aggregates from inert waste assist producers and purchasers of recycled aggregates?
- What is CE marking and how is it applied to aggregates?
The new guidance can be downloaded for free.
