Minerals Recycling

Gypsum Recycling

Tradebe Minerals Recycling helps its customers solve their inorganic waste disposal problems through recycling of materials into the UK cement industry and agriculture.

Through it's state of the art Recycling Facility at Kirkby, near Liverpool, TMR offers plasterboard recycling and gypsum recycling into a form of gypsum that can be used in cement manufacture by a number of leading cement companies in the UK.

TMR can also recycle many other inorganic wastes by utilising them as alternative raw materials in the manufacture of cement.


The main focus area’s of the minerals recycling business are :

1. Gypsum replacement – gypsum is added to clinker (raw cement) to prevent cement from setting too quickly when used, this replaces naturally mined gypsum.

2. Clinker Raw Materials replacement i.e. replacement of aluminium, silicon and calcium oxides with waste derived materials. These raw materials are mined natural resources.

Products and Services

TMR specialises in the recycling of plasterboard, gypsum and other inorganic wastes. If your waste contains gypsum or calcium, silicon, aluminium or iron then we may be able to recycle it! As well as the benefits to your company of minimising the amount of waste you dispose of and maximising the amount you recycle, you should also find that this saves you money as well!

We can look at samples of your wastes and, using sister company Tradebe Solvent Recycling’s extensive laboratories, assess it’s suitability for use in our recycling programmes. This assessment is a rigorous procedure designed to ensure that cement quality is in no way compromised by the use of recycled raw materials.

Plasterboard and gypsum recycling – “Cemset”
One of Tradebe Mineral Recyling’s major successes has been the development of “Cemset” This is the trade name given to the gypsum product. This is now supplied to many kilns in the UK.
Gypsum is a vital component in the manufacture of cement. Without the addition of gypsum, the cement would set to quickly and be unworkable. It has traditionally been a natural resource that has been mined from the ground. TMR has developed a unique process that enables the two main components of plasterboard – gypsum and cardboard – to be separated. The resulting gypsum is then blended with other materials such as other gypsum wastes to make a product called Cemset. Rigorous testing and analysis of the product ensures that it meets the necessary quality standards.

TMR can offer the perfect recycling solution for plasterboard wastes!

Alternative Raw Materials
Many inorganic wastes closely mimic the naturally occurring raw materials used in cement manufacture e.g. foundry sands are chemically very similar to the sand that is used in cement manufacture. In these instances, the wastes can be sometimes sent directly to the kilns themselves. Wastes which tend to be silica, calcium, aluminium or iron rich tend to be the types of waste which fall into this category.

TMR will be developing a recycled Alternative Raw Material for the cement industry called Cemfeed. Cemfeed tries to mimic the naturally occurring components used in the manufacture of cement – namely the oxides of calcium, silicon, aluminium and to a lesser extent iron – by the blending together of wastes that contain some or all of these elements.This process will increase the sustainability of cement manufacturing by enabling kilns to utilise greater amounts of waste and less virgin raw materials.
