About

Waste Sampling & Analytical Services

Our modern labs carry out daily sampling and advanced analysis. We follow strict protocols to assess treatability and also provide specialist testing for customers and waste handlers. For routine clear-outs, our team offers waste listing, packaging and disposal quotations, ensuring compliance and safe transport.

Packaging Sales & Cleaning

We supply both new and reconditioned UN‑approved drums and IBCs, tested thoroughly to meet industry standards. Our inventory includes PE and steel drums in all sizes, new IBCs, hazardous waste labels, and vermiculite for safe packaging. Customers benefit from cost-effective reconditioned packaging or the assurance of brand‑new certified containers.

Secure Destruction & Treatment

Our large secure site allows us to collect, treat and dispose of products or waste in bulk, palletised or finished form. We prevent inferior or off‑spec products from reaching the market by fully removing associated packaging for recycling and disposing of the waste itself. Customers receive certification of secure destruction for complete assurance.
