After a long period on the sidelines, gasification is attracting new interest.

For businesses with ready access to a good source of wood fuel - and increasingly other forms of biomass - it could be a very attractive way of producing low-cost and low-emission heat and electricity. This article overviews the technology and shares the experience of the ‘advance guard' driving this technology forward in New Zealand.

This technical guide focuses on air compressors. It reviews the general issues involved with optimising a compressed air system and identifies some of the key steps businesses can take to create some easily-won savings.

Southern Lakes Laundries has installed a high-efficiency heat exchange unit for their main industrial washing machine that is delivery savings of up to $45,000 a year.

Southern Lakes Laundries retrofited the heat exchanger into their existing equipment without any disruption to their 364 day a year operation.

The project payback period is approximately 2 years.

Virtually every industrial process generates waste heat - the challenge is to recover this heat and make use of it economically. Waste heat can be seen in shimmering boiler flues or steaming waste water discharges.

Heat recovery captures waste heat and uses it to eliminate or reduce energy required in other areas of a process or site. This practice reduces a business's overall energy bill and greenhouse gas emissions as well as improving profitability.
