Sustainability

Introduction

As a leading provider of natural stone and bespoke terrazzo products, Diespeker recognizes our responsibility to minimize our environmental impact while delivering high-quality, sustainable solutions for both commercial and residential projects.

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.

Our commitment

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.

Factory

Renewable energy: In 2025 we installed solar PV on the factory roof. The 103kW system, comprising 234 JA panels at 440W each, and 3-phase Fox ESS inverters now supplies much of the power required to run the factory and offices. We reroofed our factory to facilitate installation of more panels, at the same time upgrading insulation.

Water recycling in manufacturing: In our production processes, water is a crucial resource. In 2016 we implemented a water recycling system in our factory that reduces consumption and minimizes waste. This initiative helps us conserve one of the most valuable natural resources while ensuring operational efficiency.

Dust reduction: In another initiative, we invested in cutting machinery using water jets, to reduce the amount of dust created within the factory, much better both for our workforce, and for the environment.

Energy efficiency: We are continually assessing our operations to identify opportunities for improving energy efficiency. This includes optimizing our manufacturing processes, investing in energy-efficient machinery, and exploring the use of renewable energy sources to power our facilities.

Waste reduction and management: 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.

In-house capacity: We invested in a specialist crushing machine that enable us to make use of off cuts, reducing waste in the factory. It enables marble, granite and other stone off cuts to be crushed to the right size for use in bespoke terrazzo finishes.

Product

Exploration of new alternative materials: We are always looking out for new options to add to our materials. We have recently become the key UK supplier of Durabella, a bio-based resin style terrazzo that is ideal for poured and pre cast projects. In addition, we are exploring alternatives to traditional stone surfaces that present a similar aesthetic without depleting natural resources in the same way.

Recycled terrazzo materials: As part of our commitment to innovation, we have developed our own terrazzo product Rubblazzo that incorporates recycled waste materials from other industries, particularly construction. This not only reduces waste in landfills but also decreases the demand for virgin raw materials. Rubblazzo is made in our factory using a low carbon binding mixture.

Recycling other materials: Our in-house manufacturing expertise enables us to recycle materials, including bottles, ceramics and kitchen utensils, using these items within bespoke terrazzo mixes. These are often made at the request of the client.

Repairs: We contribute to sustainability by providing expertise in material repair and refurbishment. This means that we are able to renovate existing natural stone and terrazzo installations so they do not require replacement. Our skills in this area are industry renowned.

Responsible sourcing: Quarrying is not known for its environmental credentials. However, during recent years, the natural stone industry has been making major improvements to develop the conservation of resources, minimal waste and better waste management, as well as looking at ways to lessen the impact of the industry on pollution. Marble and granite quarrying relies on heavy plant but progress is being made with more efficient machinery and water recycling. As far as possible we source from suppliers who adhere to such ethical and environmentally responsible practices.

Transportation

Locality: The vast majority of the projects we service are within London and the South East. This keeps the impact of transporting materials to a minimum. For very local, sample deliveries we utilise an electric bike. We acknowledge that we do have projects in other parts of the UK and overseas, but we ensure that deliveries are organised to avoid multiple visits to site.

People

Employment: We provide employment to local people cutting down the environmental impact of commuting. We are proud to have a number of long-term employees and to give opportunities to young people to start their careers with us, knowing there are long-term opportunities.

Local collaboration: We are committed to fostering collaboration with local businesses including architects and designers, as well as fabricators and specialist manufacturers.

Community: We believe that supporting our local community plays its part in our sustainable aims. We have a long-term charity partnership with teenage mental health charity stem4 and have recently signed up to sponsor a local community football club.

Future Goals

While we are proud of the steps we have taken already we recognize there is always room for improvement. Over the next 10 years, we aim to:

Increase our stocks of materials with high environmental credentials, adding more as these come to market.
Collaborate with industry partners to explore such new materials and research production methods that enhance sustainability.
Further reduce water and energy consumption in our manufacturing processes.
Implement sustainability training for our staff.

Transparency and Accountability

We believe that transparency is key to meaningful sustainability efforts. As such, we will regularly review and report on our progress against these goals. We welcome feedback from our clients, partners, and stakeholders to help guide our journey toward greater sustainability.
