Variable speed drives (VSD’s) are used in conjunction with induction motors, and exploit the fact that a motor’s speed is proportional to the frequency of the… Read More »How Variable Speed Drives Reduce Resource Costs
Resource efficiency in the industrial sector is fascinatingly complex. Industrial sites employ a wide variety of materials, resources and processing equipment, all arranged into various… Read More »Resource Efficiency Breakthroughs Require a Systems Approach
Crisis? What crisis? Water shortages in Gauteng have been looming for years, and even when additional water is finally sourced from the Lesotho Highlands through… Read More »Gauteng Water Crisis – What Should Industry Do?
Oil-filled screw compressors are used extensively in industry, and are favoured for their large capacity, relatively quiet operation and flexibility. The latest innovation with these… Read More »When to use Variable Speed Drive (VSD) Screw Compressors
Power companies make it their business to generate electricity as cheaply as possible. It is not uncommon to find coal-fired boilers operating at efficiencies in… Read More »Why Large Steam Users Should Consider Cogeneration
Energy is measured in many units, even within single measurement systems, and hence it is not surprising that, particularly for non-quantitative types, people often get… Read More »The Simple Power of the kilo-Watt Hour
Induction motors are often described as the “workhorses” of industry, and can be found in every factory. In many plants they are the largest consumers… Read More »Energy Efficiency Opportunities Associated with Induction Motors
Despite increasing scarcity, water is still a relatively cheap commodity and this is perhaps why, except for the most water-intensive industrial sub-sectors, water is often… Read More »Water Management Considerations for Factories
Technology is an important tool for maximising the resource efficiency of a manufacturing plant, but even the most efficient technologies require maintenance and management. The… Read More »Using Process-Level Management Systems to Drive Resource Efficiency
There are many overlaps between operational excellence, resource efficiency and broader sustainability issues. Improving product quality reduces rework and saves raw materials, energy and water.… Read More »Does Your Factory Have a Resource Efficiency Strategy?
