Plasterboard and Gypsum Recycling

Park House Services Ltd can accept plasterboard waste for processing at our Rakehead Transfer Station.

The process involves the crushing, sieving and separation of the gypsum plaster from the paper. Re-use can be back into cement and gypsum products or agriculture.

Recycled Gypsum use is increasing within the UK. The reduction of atmospheric deposits of Sulphur onto UK agricultural land is driving a need for sulphur fertilisers.

Sulphur can become one of the main limiting factors to crop yield, where it is important in the uptake and utilisation of Nitrogen.

Recycled Gypsum not only supplies a valuable source of Sulphur, Calcium and Magnesium; the material is also an important soil conditioner.

Gypsum (Calcium Sulphate) has always been used in agriculture but more recently recycled grades of material have made gypsum more cost effective to farmers.

Gypsum in Agriculture

Here are a few of the advantages of using recycled gypsum:

Improves soil structure and tilth, particularly on heavier soils. Gypsum aids development of deeper, more friable soil, with less hard clods, reducing the energy requirements for seedbed cultivations.

Increases flocculation of clay particles making soils more permeable with improved drainage, aeration and moisture retention.

Improves aggregate stability, reducing capping, run-off and soil erosion, in unstable sandy and silty soils.

Allows soils to dry out more quickly following rain or irrigation, enabling it to be worked sooner.

Binds organic matter to soil and can help prevent soil erosion.

Improves skin finish in potatoes with fewer growth cracks.

Gypsum is a source of the essential plant nutrients Sulphur and Calcium with both major nutrients readily available.

Calcium within gypsum is more soluble than from ground limestone, this means the Calcium from gypsum naturally migrates across the soil profile.

Gypsum has a small neutralising value (CaO equivalent between 1-4%), making it particularly useful when increasing soil Calcium levels without needing to alter soil pH.
