June 24, 2024Energy Management Systems – Injection Molding 1Injection molding machines have ‘base’ and ‘process’ loads and an idling machine is not ‘free’, it is costing large amounts of energy and money. Read more
April 16, 2024Energy Management Systems – The Gas BillMost plastics processing sites use gas simply for space heating but some processes use gas as part of the process, e.g., rotational molding. Where gas is used for hot water only then this is generally relatively constant over the year. For space heating, the gas use load will be related to the weather conditions (how cold it is) and the weather is then a ‘condition’ driver for gas use. Read more
March 14, 2024Energy Management Systems – Assessing PerformanceIn most plastics processing electricity is the main energy source. Electricity use is not, as is sometimes thought, fixed and uncontrollable, it is variable and controllable. For most sites, the electricity use will be directly related to the production volume in a given time period. Read more
January 25, 2024Energy Management Systems – The Electricity BillMany sites simply get the energy bill from the supplier and pay this some days later by direct transfer from their bank. The bill is not examined for accuracy or for potential areas to reduce costs and sometimes the production people don’t even see a copy of the bill – even though they are responsible for using most of the energy.

January 2, 2024Energy Management Systems – Site SurveysCarrying out a full site survey is a specialist task but a mini-survey or walk-around will quickly and easily identify many actions to reduce energy use. Naturally, the focus will be on using that essential tool called the ’OFF switch’ but this can have remarkable rewards very quickly. Read more
December 7, 2023Energy Management Systems – Integrating Energy into the AccountsOne of the quickest ways to start to control energy use is to integrate reporting into the accounts package (along with all the other vital business numbers). Energy use and management is not a ‘technology fix’, it is a vital business measurement and tool. Some of the most effective energy management efforts can come directly from the accounting function.
