Waste Analysis Case Study — Tom White
UK Waste streams are evolving. Updates to the way food is packaged and ever-changing consumer buying and recycling habits are making predicting the types and levels of materials found in our bins and skips increasingly difficult. This poses an issue for waste management companies such as Tom White, which is helping to reduce the amount of waste that ends up in landfills by providing select waste processes that create valuable materials for reuse.
WHO ARE TOM WHITE?
Now owned by Coventry City Council, Tom White specialises in ethical waste management that focuses on putting people first, protecting the planet and generating profit for purpose. They have been delivering specialist waste management services to homes and businesses across Coventry and Warwickshire for over 40 years.
Through the use of their onsite Materials Recovery Facilities (MRFs), they (Tom White) can recover recyclables such as cardboard, plastics (rigids and films), wood and metals (ferrous and non-ferrous) with the residual going into a fuel (RDF). This helps Tom White reduce the number of reusable materials that end up in landfills.
To better understand what is going through their plants, Tom White must know what is in their waste. This is best done through high-quality waste analysis, which can then build a clear and reliable profile of the materials they receive.
Michael Trueman, Head of Production at Tom White, had been recommended Alfred H Knight as a reputable provider of waste analysis services:
“We wanted to implement material analysis to firstly better understand the composition of the materials we produce. With the challenges associated with the fuel and fines markets, we needed data to engage new outlets to provide a contingency for the business. I got in touch with Sam Jeynes (Business Development Manager at Alfred H Knight) who is based nearby. He was nice and friendly and always made our business feel loved, so we knew they would be a good fit for us.”
As an industry-leading inspection and testing company with strategically located hubs throughout the UK, Alfred H Knight was able to provide sampling for fines at two of Tom White’s sites, Loss On Ignition (LOI) testing to check the inert waste for combustible organic matter and WM3 analysis to ascertain the chemical content of the waste to ensure it wasn’t potentially harmful and it is fit for landfill cover. This service helped Tom White to meet the guidance and statutory requirements needed to minimise the amount of waste produced and increase the use of non-landfill waste management options.
As they were satisfied with the service they received, Tom White asked AHK to undertake some RDF analysis too, consisting of a test for composite materials left in RDF and a chemical analysis which included the calorific value (CV) of the material to meet EFW requirements.
Alfred H Knight’s team of experienced and highly qualified experts and laboratory technicians went to work to provide Tom White with a full suite of analytical services, including Compositional Analysis, Loss on Ignition, Sizing Analysis, Density Analysis, 2D and 3D Analysis and Particle Size Distribution.
“From the fuel analysis that Alfred H Knight provided, we were able to determine the CV of our RDF, which then opened us up to have conversations with multiple outlets, whereas originally we were limited to just the one. Without these further outlets, the materials would have ended up in landfill”
FURTHER SUPPORT
When producing fuel, it’s imperative to understand the makeup of the material that you are receiving. As Tom White was satisfied with the service they received, they asked Alfred H Knight to undertake some RDF analysis too, consisting of a test for composite materials left in RDF and a chemical analysis which included the calorific value (CV) of the material to meet EFW requirements.
Alfred H Knight’s team of experienced and highly qualified experts and laboratory technicians went to work to provide Tom White with full breakdowns of input materials through expert analytical services including Compositional Analysis, Loss on Ignition, Sizing Analysis, Density Analysis, 2D and 3D Analysis, and Particle Size Distribution.
Input materials were then categorised in terms of their characteristics; flat and crumpled (2D/3D); the size of the material; <10mm, 10-60mm, >60mm and the content of the material; plastics by type, wood, non-combustible material, cardboard, textiles. This provided Tom White with a comprehensive understanding of their waste streams, enabling them to improve their fuel production.
