Responsible
and grounded
The nature of our industry presents challenges to sustainability, and we are committed to addressing these with transparency, innovation, and action.
We acknowledge that there is along way to go to achieve top quality green credentials, but we will endeavour to look at every opportunity to make improvements.
We are committed to implementing practices that reduce our carbon footprint, minimize waste, and conserve natural resources wherever possible.
While we strive to continuously improve our processes, we are also committed to providing an honest and realistic approach to sustainability. This includes avoiding any form of “greenwashing”, making claims that are purely to tick boxes but have little foundation in fact.
No greenwashing
We publish actions with numbers, acknowledge trade-offs and share what’s next.

Factory operations & energy
Our factory has been located at Ormside Street since 1984. Making improvements to any older style factory in terms of sustainability will always pose challenges, but Diespeker is facing these head on. Initiatives include:
Renewable energy
A 103kW solar PV system installed in 2025 now supplies much of the power required to run the factory and offices.
Water recycling
In our production processes, water is a crucial resource. Implementing a water recycling system in the factory reduces consumption and minimizes waste, helping to conserve one of the most valuable natural resources while ensuring operational efficiency.
Energy efficiency
Continual assessment of operations identifies opportunities to optimize manufacturing processes by investing in energy-efficient machinery. The factory was reroofed in 2025 to enable installation of additional solar panels, at the same time upgrading the building’s insulation.
Waste reduction
In addition to recycling materials in our terrazzo products, we aim to minimize waste generated during installation and production. We work to implement best practices in waste segregation and collaborate with local waste management services to recycle or responsibly dispose of materials.
Dust reduction
Our cutting machinery uses water jets, reducing the amount of dust created within the factory. This both lessens the impact on the environment and improves working conditions for the factory team.
In house recycling
Our specialist crushing machine, nicknamed Jaws, allows us to make use of stone off cuts, reducing waste in the factory. It enables marble, granite and other stone off cuts to be crushed to a variety of sizes for use in bespoke terrazzo finishes.
Transportation & locality
A proud London based business, Diespeker is fortunate to have superior storage facilities right in the heart of the city. This has a positive impact on resources needed to transport slabs and products, as well as delivering to many projects.
01
Bulk buys
Marble, granite and other materials are sourced by every stone business from around the world, from Italy to China.
Due to our onsite storage capacity, Diespeker can order in bulk, meaning shipments are minimised as much as possible.
02
Local client base
While we have clients around the UK and internationally, the majority of projects are based in the London area. This means that we can keep transportation demands to a minimum, reducing emissions and fuel usage.
Visitors to our factory are encouraged to take the underground to nearby London Bridge rather than drive.
03
Going electric
We have started small with an electric bike for local sample deliveries. For the future we are looking into the practicalities of switching to electric vans for larger deliveries, for example countertops and splashbacks.
Products & materials
Much of the stone used in our industry is quarried. Whilst there have been moves within the quarrying sector to improve environmental credentials, there will always be a negative impact from taking stone from the ground, wherever it comes from in the world.
However, at our end of things we are working hard to make a difference.
Repairs & reburbishment
Stone can be damaged over the years. Rather than replace entire surfaces due to damage, Diespeker’s skilled team can often make repairs that bring surfaces back to a superb condition. The process requires careful matching and sourcing materials as close to the original as possible.
As well as keeping damaged stone out of landfill, this expertise means that heritage surfaces remain intact.
Custom mixing for bespoke results
Using recycled materials requested by clients is a specialist skill overseen by our bespoke team, to ensure integrity of the finished product.
Examples include crushed beer bottles, Maltese glass fragments, sand, crushed bricks and blocks salvaged from building work.
Rubblazzo
Our in-house product that uses rubble from demolished London buildings as aggregate within a cement-free, ultra-low carbon mix to create an eco-friendlier material.
Rubblazzo is ideal for exterior use and has also been commissioned commercially reception desks and countertops.
Alternative methods
In 2025 we joined forces with Dutch flooring specialist Duracryl to introduce Durabella, a groundbreaking, eco-conscious poured terrazzo. This innovative material is made using Duracryl’s proprietary, chemical-free biopolymer derived from vegetable oil. It contains no substances listed on the Red List and boasts a remarkably low carbon footprint of just 1.6kg/m².
We have now transitioned all production of non-standard poured and precast resin terrazzo to Durabella.
People & community
Diespeker is a compact enterprise, with a focus on our local community.
Local employment
Our teams, from office staff to the factory crew, mostly live in the South London area, reducing commuting miles. Our MD lives further away in Wimbledon but either runs or cycles to work every day, having a very low impact on the environment!
Long term careers
Diespeker attracts hard workers who often stay with us for the long-term. We have plenty of long-service team members who appreciate our family-style of business.
We see the provision of secure employment as important in our sustainable aims.
Local business collaboration
Our factory is based in an area that is home to a diverse range of businesses that complement the work that Diespeker does, from metal legs and frames for bespoke tables to fittings for kitchen worktops.
We frequently collaborate with these businesses, as well as local architects and designers.
Community engagement
Sustainability to us also signifies looking after those in our community. We have partnered with teenage mental health charity stem4 for over 10 years now, raising funds and awareness of their crucial work.
Over the years we have also supported Alzheimer’s Society and Holly Lodge Centre through participation in the London Marathon. We also provide sponsorship for a local amateur football club.
Our 6 year roadmap
While we are proud of the steps we have taken already we recognise there is always room for improvement.
