Project Overview
As the UK’s leading manufacturer of natural stone and concrete landscaping products, Marshalls PLC were looking to reduce their Carbon footprint and energy Costs at their manufacturing sites across the UK. Clark Controls were brought in by Richard Capper MEI (Group Carbon & Energy Manager) to advise and provide solutions to numerous challenges faced by the environmental and sustainability team.
The Marshalls Civils and Drainage site based in Pollington had numerous issues with onsite heating and product curing. The goal was to improve the energy management capabilities and reduce heating energy consumption without affecting product curing in the manufacturing process.
Challenges
Marshalls faced a many key challenges with this project. A lack of onsite control meant that unoccupied areas were heated, whilst other occupied areas received inadequate heating. This led to excessive heating consumption and therefore, costs.
In addition to this, as heating was used as part of the product curing process, being able to regulate temperatures was essential.
Solutions
Through the process of a site survey, joint agreement on ambitions and targets, and Installation of a Clarke Controls EMS, we were able to achieve all of the required objectives.
Results
The Clarke Controls EMS provided the ideal solution to the management challenges and exceeded all expectations. The system was installed in Jan. 2021 and despite COVID based challenges, delivered excellent results.
- By March 2022, verified savings on gas spend had exceeded £109,730.
- Improved culture of onsite energy management through behavioural change
- Exceeded predicted return on investment.
- Improved operational control of manufacturing curing process.
- Full operational control of heating, with cloud based access, management and reporting
Conclusion
Richard Capper MEL (Group Carbon 8 Energy Manager for Marshal’s PLC) confirmed that Clarke Controls had exceeded all expectations and achieved outstanding results to date, in what has been a very challenging year due to COVID-19. and commented “I wanted to work with a company that had the experience and expertise to address our energy management Issues. and that company was Clarke Controls. The results speak for themselves”.
