Tarmac Topblock shows energy-saving focus with a Spirax Sarco heat recovery system

Tarmac Topblock is moving closer towards hitting its key sustainability target of achieving a 5% reduction in energy usage by 2010, thanks to the energy-saving benefits of a Spirax Sarco Engineered System that recovers heat from waste steam.

 

Tarmac Topblock's Alfreton factory manufactures aircrete blocks for the construction industry. The blocks are mixed and moulded, before curing in a bank of eight autoclaves fed by steam at pressure.

Instead of sending the vented steam from these autoclaves into atmosphere, the Spirax Sarco Engineered System now feeds the steam through a heat exchanger to pre-heat the site's boiler feed water.

"Making our operations more sustainable and environmentally efficient is a key focus for us at every level of the Tarmac Topblock business," says Robin Stapleton, engineering manager at Topblock's Alfreton site. "The Spirax Sarco system will help us to further reduce carbon emissions year-on-year and help us to achieve our energy saving targets."
