Closed Loop Initiatives
Managing our business responsibly from day one
Closed Loop
Recycling
Powerday works to move waste as far up the waste hierarchy as possible, and keep materials in the circular economy. Whilst much of the waste we handle is hard to recycle, and reuse presents even more challenges, we are always looking for innovative approaches to our clients’ materials. We are making huge strides in diverting waste into closed loop recycling, particularly in the following areas shown below.
Window Glass
In early 2023, we started collecting and crushing window glass from a refurbishment of over 640 apartments on the Chalcots Estate in Camden for client McLaren Construction. The works on the Camden Council owned high-rise tower blocks include the replacement of just under 3,500 windows.  The cullet (crushed glass) is recycled back into window glass by leading global glass manufacturer Saint-Gobain at their UK site in East Yorkshire.  The new windows have a recycled content of up to 30%, replacing a significant amount of virgin material through this closed loop process. In principle, glass can be recycled endlessly but in practice, it is a challenging proposition. The process requires good quality flat glass (recycled bottles are not suitable) which is only possible if the material is separated on site and if all supply partners are committed to ensuring that the product remains clean at every stage. We are pleased that this collaboration has proved successful and we have recycled over 150 tonnes since the start of the project in 2023.
Twinwall Corrugated
Plastic Sheeting
Since 2022, we have had a partnership with temporary protection material supplier, Protec, to provide closed loop recycling services for Proplex to construction sites across London and the South East. We offer collection services for Proplex and other correx sheeting of any size, colour and thickness. We then bulk and bale these materials before transporting them to Protec’s manufacturing facility in Sheffield. This plant enables Protec to recycle and remanufacture these waste materials into new ProplexRE products, in place of virgin polymers, in a closed loop process.  The partnership is going from strength to strength, saving over 185 tonnes of correx, which has been repurposed back into over 220,000 sheets of temporary protection.
uPVC
Windows and Door
Since 2022, we have also been working with PDA Plastics who create new uPVC windows and doors from waste uPVC products. We collect, store and bale these materials before they go to PDA Plastics plant in Kent where they are shredded and granulated before being cleaned and colour-separated. The products then go to uPVC window manufacturers across the UK to be made into new uPVC windows. uPVC windows can be recycled up to ten times, greatly extending their lifecycle.
Community Wood
Recycling
In the 2021/22 financial year, we rescued 124 tonnes of wood waste, up 30% from the previous financial year, by working with Community Wood Recycling. Of the 124 tonnes, 77.4 tonnes were reused, 3.3 tonnes used as firewood and 43.5 tonnes recycled, saving 62 tonnes of CO2e! We understand the importance of sustainable waste management and circular economy, and that’s why we work with companies like Community Wood Recycling to ensure the waste we collect from our clients goes as far as possible.
Woodchip
In 2025, we sent over 12,000 tonnes of waste wood to be repurposed back into chipboard. We work with Egger to repurpose wood that we collect and receive from construction sites, back into building products.
EGGER materialsare found in countless products, including kitchens, bathrooms, bedrooms, offices, hotels and shops. EGGER is a full-range supplier for the furniture industry, interior design, wood construction, and wood based flooring industries.

What is Closed Loop Recycling?
Recycling, and more specifically closed loop recycling, is a major part of both the waste hierarchy and the circular economy. We explore what it actually means for your waste….
Recycling as part of the waste hierarchy
The waste hierarchy prioritises the management of resources in order of their impact on the environment – from most favoured option (prevention) which has the least impact on the environment, to least favourite option (disposal in landfill) which has the highest impact on the environment. Recycling sits in the middle of these options, enabling resources to be reprocessed and used in new products, in place of virgin materials.
