REGYP hits a milestone

July 1st, 2010|

REGYP has recycled and sold more than 10,000 tonnes of high quality recycled gypsum. This means REGYP has successfully diverted 10,000+ tonnes of plasterboard waste from Landfill reducing the demand on the environment and mined gypsum resources. REGYP's gypsum products are high quality with a guaranteed purity of 90%, and general monthly test results showing

Plasterboard waste – Contamination

May 26th, 2010|

Waste Loads • All waste loads are inspected at REGYP disposal points; • Up to 2% contamination allowed (screening equip limit); • PENALTIES are imposed for contaminated loads; • A “Customer Code” is required to tip at the REGYP disposal points; • A payment method must be arranged before tipping or pickup. Acceptable Waste We

Gypsum spreading trials

February 12th, 2010|

ReGyp undertook spreader trials using the Super Ag 10mm screened gypsum product near Cowra NSW. The results off the spreader are substantial, with the Regyp gypsum spreading up to 19m (average 17-19), with various NSW mined gypsum products only achieving 11-13m off the same spreader. This increased spreading distance would equate to approximately $10 per

Aerial top dressing with Super Ag Gypsum

December 12th, 2009|

Regyp Super Ag Gypsum is more suitable to aerial top dressing due to the material handling properties, spreadability (similar to prilled products) and the increased solubility. In general aerial top-dressing contractors, to tend to use coarser gypsum material to overcome material handling issues and also to deliver the recommended quantities more quickly. The influence of

Effect of gypsum on subsoils

October 14th, 2009|

Many soils in NSW have sodic clay subsoils of low permeability. These soils waterlog easily after heavy rain or irrigation. Under these circumstances subsoil oxygen levels remain low for long periods during which root development is seriously restricted. Waterlogging also favours the development of root diseases, including crown rot and Phyrophihora. and the loss of

Effect of gypsum on topsoils

October 14th, 2009|

Gypsum improves the soil structure of hardsetting or crusting sodic clay topsoils, not only by reducing swelling, but also preventing clay dispersion. Sodic topsoil (0-10cm) usually has very poor structure – it is waterlogged when wet and too hard when dry. Sodic soil has too much sodium linking clay particles and not enough calcium. Sodic

Improving soil structure with gypsum

October 14th, 2009|

Gypsum works on improving spoil structure in two ways. Both depend upon the gypsum being dissolved by rain or irrigation water and entering the soil solution. The first is called the electrolyte effect which is based on the fact that swelling and clay dispersion of sodic clay soils decrease as the salinity of water infiltrating

Sodic Soils

October 14th, 2009|

Sodicity should not he confused with salinity. Salinity refers to the total amount of salts dissolved in the water in soil, whereas sodicity refers to the exchangeable sodium cations bound to clay particles. Salinity can be reduced by leaching (draining rainwater or non-saline irrigation water through the soil but leaching has little effect on sodicity.
