Trommel Fines Recycling

Trommel fines are produced as part of the recycling process and consist of materials such as stones, aggregates and glass; they have traditionally been treated as an inert product and sent to landfill. However, trommel fines also contain materials such as fibre, films, rigid plastics, organics, wood, metal and textiles. These are classed as contaminants and should be separated and removed before landfill.

The Problem

Trommel fines are produced in several key waste streams with the most critical being from municipal solid waste which consists of approximately 45% contaminants.

Separation technology for tackling trommel fines has been operating in the UK market for a number of years, but never has it been so important for waste operators.

The fibrous nature of these fines often makes them difficult to separate and recycle so they have traditionally been sent to landfill but this only deters the problem rather than solving it.

Sending trommel fines to landfill not only results in a considerable cost for waste operators but also does not align to the Government’s Sustainable Development Goals (SDGs) and drive to create a circular economy.

The Solution

Turnkey processing systems from CDE provide maximum recycling potential and full water treatment achieving considerable reduction in waste to landfill. CDE systems are currently processing trommel fines for customers throughout the UK, including a 50,000 TPA recycling plant at Eastern Waste Disposal in Essex. CDE’s recycling solution accepts and processes not only trommel fines but also 
road sweepings and gully waste.

Through extensive research and process trials on a range of customer sites, our trommel fines recycling solution removes contamination from sand, grit and stone, liberating unwanted lightweight matter.

The recycling solution produced for trommel waste incorporates some of the latest wet processing technology in the industry such as the AggMax, G:MAX, and CO:FLO.  The turnkey solution can accept up to 30 tonnes per hour of trommel fines waste that can be washed and sorted in order to recover as many valuable resources as possible.

The Result

Our recycling solution can divert up to 70% of trommel fines from landfill. By washing the inert materials to remove contamination, clean sand and aggregates extracted from the trommel fines waste can be resold and reused in the secondary aggregates market to close the loop on waste.

Extracting as many resources as possible from the trommel fines waste, businesses can save on huge landfill disposal costs and generate additional revenue from the aggregates produced.

CDEnviro ensures customers can  treat trommel fines as a resource, not a waste. As well as producing revenue generating sand and aggregate, CDEnviro systems also produce the remaining constituents, formerly known as contaminants, as a product which can be used for refuse-derived fuel and solid recovered fuel. Revenue generating uses for the sand and aggregate include pipe bedding, landscaping uses and sub-bases, resulting in far-reaching environmental benefits
