4R Recycling works with many different industries and waste producers recycling a wide variety of by-products in the most beneficial ways possible. We look at all of the recycling options available for a particular by-product before agreeing the best solution for our client.

By-products handled by 4R Recycling will be recycled in various ways, including:

• Applied directly to agricultural land as soil conditioners and fertiliser replacements
• Used for the manufacture of soils in land restoration schemes
• Composted and applied to agricultural land or restoration sites
• Digested (aerobic or anaerobic) and applied to agricultural land or restoration sites
• Utilised in the production of fertiliser replacement products
• Mixed and blended to produce quality livestock bedding

Before any by-product is recycled it is subjected to thorough technical scrutiny by our government trained soil scientists and in-house Technical Team. This process can involve chemical and biological testing, plant growth trials (Bioassays) in our glasshouse facilities, leaching tests and field experiments to prove that the by-products confer agricultural benefit.

What Can we Recycle?

We have the experience and technological knowhow to recycle practically any by-product. With many decades of experience, we will most likely already have some knowledge and ideas of how to recycle your particular by-product and we will probably have done it before. If it is a new material or technology to us, we are perfectly placed to explore and develop new options, calling on our sister company 4R Environmental Consultants for input as required.
