Most industry-grade process heating systems are based on steam or hot water from boilers that today mainly burn fossil fuels like oil, gas and coal, or electricity generated by different sources.

Solar process heating systems can supply up to 20-30 % of the heating demands of an average plant. This is called the ‘solar fraction’. As a renewable energy source, low-temperature solar thermal technology has huge untapped potential. Solar thermal can be backed up by other heat sources and combined with storage systems for guaranteed supply.

The art of water saving

• Awareness-raising and practical measures save water on campus
• Reduced annual water consumption by 1 183 m3 and cost savings of around € 2 660

London Metropolitan University is one of the top five universities in the UK for reducing carbon emissions and a finalist in the 2012 Green Gown Awards for reducing its environmental impact.

Companies are trying to use more sustainable processes and resources to match growing environmental and social awareness. Changing processes and resources incur some costs for the companies, but can lead to profit if properly managed. For these costs to turn into profits, the sustainability of the products must be effectively communicated to the consumers. Hence, adopting a smart marketing approach is important to be successful in a market where companies are competing over their 'green' image.
