Placing the spotlight on people, not just data.

Kudos in Construction Logo

Barbour ABI are creating a monthly series documenting the best the construction industry has to offer. Not organisations, not data-led research, but the people, those people that are championing a cause or producing excellent work in a particular field of expertise.

Our Focus This Month: Recyclable Materials and Waste Management

The construction industry is the biggest consumer of natural resources and equally, it is a high contributor to waste landfill, an effect on the world that is now becoming critical to tackle. The understanding is that the construction industry needs to evolve its practice when using natural resources by reducing and promoting recycling and reusability. The key to this is material efficiency and promoting greater sustainability of materials.

This month Barbour ABI is voicing their appreciation to those amazing people who are doing all they can to get people thinking green, sustainability and recycling within the construction industry, giving kudos to those guiding their organisations on a pathway towards a circular economy by reducing waste landfill and using recyclable materials to drive a clean and safer environment.

Key Features


Nigel Van Wassenhoven and Reiss Salustro-Pilson,
Founders @ Enviromate

Enviromate was Designed with one core goal; to encourage and promote sustainable construction through the re-use of surplus building materials at all levels within the industry.

Bio and Background:

Nigel Van Wassenhoven and Reiss Salustro-Pilson created Enviromate in 2014 to enact change within the construction industry by developing an online marketplace for construction companies to trade their waste – anything from sand to tiles.

The platform connects consumers to resources they wish to sell through a secondary marketplace, harnessing digital technology and economic principles that propel circular economy growth. Instead of wasting under-utilised materials, the platform ensures reusable materials are just that, reused.

Their start-up meant that they were both nominated for the Observer Ethical Awards in 2015.

Construction Kudos:

Enviromate has revolutionised the construction industry through the acceleration of reusing surplus and leftover building materials, with a vision to build a better future to reduce the impact on the environment and support needed for progressing towards a circular economy.

The construction industry is responsible for nearly 32% of landfill waste, and Enviromate seeks to make the world a better place by making ethical choices and using sustainable materials to support a sustainable planet. A self-funded platform that has earned Pioneer of The Year and a Great British Entrepreneur Award


Enviromate has kept 50,000 tonnes of material out of the waste stream, totalling up to around £2 million.
