ETM operates an integrated waste management system (IWMS) certificated to ISO 14001. It is a requirement of our IWMS to continuously improve and ETM places material testing as the core of our continuous improvement programme.
ETM manages a range of waste streams for clients that can be recycled back into fully recovered ‘End of Waste’ recycled aggregates. In order to do this we have implemented strict protocols to ensure that the aggregates we produce perform in exactly the same way as quarried aggregates.
Our main products are Type 1 and 6F5 recycled aggregates and these are tested in accordance with our WRAP Quality Manual to ensure that the WRAP Quality Protocol for Recycled Aggregates is complied with in full. We use ACS Testing Ltd to do all our Grading and Constituents test on a monthly basis and full chemicals testing in accordance with Specification for Highway Works (SHW).
In addition to ACS testing we undertake a variety of other lab testing in accordance with our WM3 compliance systems and this has led to ETM pioneering a new approach to the management of contaminants involving Total Petroleum Hydrocarbons and benzo(a)pyrene. ETM has partnered with MTS Environmental Ltd to undertake rapid testing of material to identify the correct route for ‘Asphalt Wastes Containing Coal Tar’ (AWCCT) using UV spectroscopy rapid testing technology. This ensures that all ETM recycled aggregates are not contaminated when used back into highway works.
By continuously testing our materials in accordance with the specifications and investing in new technology we have been able to continuously improve the quality of aggregate used in the construction of ETM and client highways schemes. Our clients now see our material in the same way that they used to see quarried aggregates; only our material has significantly less embedded carbon and we are protecting the raw aggregate resources for future generations.’
