Climate change series: Focus on energy management 2

An account of how John Baarda Ltd achieved increases in energy efficiency in tomato production by using waste carbon dioxide and steam from fertiliser manufacture.

By appropriate location of a new glasshouse complex, tomato growers John Baarda Ltd have been able to recycle the carbon dioxide and steam produced in the manufacture of nitrogen fertiliser by Terra Nitrogen. Tomato growth is boosted by the increased concentration of carbon dioxide and the steam is used to heat the glasshouses, so enabling year-round tomato production. This has reduced costs and the food miles associated with importing tomatoes in winter.
