The improvements made so far have brought environmental savings of 46 tonnes of carbon dioxide equivalent (CO2e) and 300 m3 of water, which have generated cost savings of £27,600 per year. These annual savings have been accruing, year-on-year, to give the £118,400 cumulative savings to date.
Overall, more than 13 separate improvement opportunities have been identified on site.
Booth has been supported with improving its stock management so that foam is purchased in bulk, in larger containers, to help reduce packaging and the amount of foam residue left in each container.
An automated dosing system has also been introduced for distributing raw materials, to help reduce wastage and together, these initiatives have brought annual savings of £11,200, with a six month payback period.
Another project has involved designing a new kind of drinks dispenser that uses recyclable metal coils within an aluminium block as a heat transfer medium, rather than traditional water baths.
This has helped to make the products more efficient, and saved Booth more than 800 kilowatt-hours (kWh) of electricity and 57 m3 of mains water per year.
More recently, Groundwork Pennine Lancashire turned its attention to energy efficiency, and generated further annual savings of £5,500 and over 30 tonnes of CO2e.
A compressed air survey was carried out and identified leaks have since been repaired, to help reduce annual gas bills.
A review of lighting also resulted in sodium lamps and energy-intensive fluorescent tubes being replaced with more energy-efficient alternatives. New sensors were fitted, to support a new 'switch-off' policy in areas that are unoccupied or have sufficient natural light at certain times of day.
Steve Bancroft, senior quality engineer at Booth said: "Groundwork’s 21 years of experience provides a valuable resource that has helped us to save money, reduce carbon emissions and identify opportunities for improvement. We look forward to continuing our relationship, to help build a more successful and sustainable future."
Further identified energy-saving opportunities include upgrading old boilers in the offices to more energy-efficient condensing models, fitting variable speed drives to make equipment more energy-efficient, and optimising heating controls.
A thermal imaging survey has also been carried out and work is now underway to improve pipework and tank insulation, to help reduce heat loss.
