one energy source, but how to optimise decentralised systems with various fuel sources to achieve energy efficiency, reliability and criti- cal process protection. A typical scheme could comprise renewable power generation sources such as wind and solar. However, these pose challenges to system reliability and performance, given their inherent intermittent contribution and associated disturbances. Gas-to-power programmes in Southern Africa are yet to overcome challenges such as natural-gas pipeline infrastructure and moderating market prices. Diesel-engine power plants have synchronous technology and contribute a high level of operational stability for standby or prime power applications, together with mature diesel-fuel supply chains. Manufacturers of diesel gensets are making steady technological gains that reduce capital intensity and emission levels, and enhance power output and efficiency. Diesel-generated power is still likely to feature on its own or incorporated into hybrid solutions for many more years. Bibliography [1] Overton TW. Diesel Gensets Aim at the Future.

CDE South Africa keeps it clean

CDE Global is the largest wet processing equipment manufacturer in the world and works with its customers to maximise their return on investment and gain significant competitive advantage while minimising environmental impact. The company has established an office (CDE SouthAfrica) in SouthAfrica and appointed Nicolan Govender as Regional Manager for Southern Africa. The African continent has high infrastructural demands and the materials washing solutions CDE develops are ideal for quarrying and mining sectors supplying the construction market. By using CDE equipment, the environmental benefits are significant, not the least of which is that up to 90% of the water is recycled when a wet processing washing plant is combined with a CDE AquaCycle water recovery system. A typical sand washing operation uses a minimum of a hundred thousand litres per hour, which is basically clean water being converted into waste water and then pumped or piped away into a settling dam, at which point it exits the washing

system.With a CDEAquaCycle, 90% of this waste water is recycled for immediate reuse by the customer.This does not only minimise water consumption, but also aids businesses to show compliance when reapplying for water licences. Enquiries:Visit www.cdeglobal.com
