Modern factories are investing in technology to reduce their energy consumption, costs and CO2 emissions. This is not new, but the process of digitalisation and decarbonisation has accelerated to meet global energy transition and sustainability goals.
In addition, the constant increase in energy costs pushes companies to become more efficient and reduce overall expenditure to stay competitive. If you want to reduce your internal costs to avoid increasing prices charged to your customers, you have to seek cost-saving options. You can start by establishing energy efficiency measures.
Worldwide, manufacturing is a major energy consumer. In the UK, the industrial sector accounted for 17% of the total consumption.
Fortunately, given this high percentage of energy consumption, there are options available to use it more efficiently and even reuse it. Waste heat from your machines is a source of energy that you can exploit.
What is this residual heat?
Waste heat or residual heat is the heat produced by your machinery when creating products and by-products. It can be intentionally-created heat or heat released from the simple industrial manufacturing process (metals, automotive products, tiles, food products, etc.).
It can be qualified as a consequence of the production process, usually lost in the air. This is perfectly normal, as your operations team is ensuring that the production process is running smoothly and at a good pace. You might however be interested to know that some of that heat can be harnessed as an energy source in your factory.
Interesting, isn’t it?
In this article, we look at how you can utilise that waste heat to generate energy, the benefits it can bring and how to measure the impact of your utilisation strategy.
