The commercial waste that arises at the drilling site is stored in special-purpose containers until it can be collected by licensed disposal companies. Detailed records of all the waste streams are kept. 

The drill cuttings are removed from the drilling mud after each circulation cycle, meaning that the mud can be re-used. Particles upwards of 4 microns (┬Ám) are separated from the drilling mud. The filtered solids are used by other industries as raw materials. Reducing the use of mud additives and recycling drilling residues helps to minimise environmental impacts.
