Sustainability at LECA...

Leca® Lightweight Aggregate Expanded Clay (LWA) is mainly known for its functional benefits, with a long history which dates back to more than 75 years, Leca® LWA is actually more modern than ever – and a highly resource efficient material within infrastructure, housing and water management development projects.

Leca® (LWA ) has been around since the 1940’s and although the product has been developed further since then, it is basically still the same product: expanded clay. This special and purposeful material is highly suitable for many building requirements due to its numerous and unique properties, we like to call it All-in-One, Everywhere. But Leca® LWA has some very positive and beneficial 'side effects' regarding environmental issues including resource efficiency and a sustainable long lasting lifetime.

Environmental and sustainable issues which were probably not the main focus 75 years ago, is certainly a concern today in the modern world.

Our Sustainable Identity

 

Sustainable Material which can be Reused

Nature's Natural Resource

 
 

RESOURCEFULNESS FROM CRADLE TO GRAVE – AND RESOURCEFUL IN BETWEEN!

To make this simple, we transform 1m3 of freshly dug clay into 5m3 of lightweight expanded clay aggregate construction material. Through this highly resourceful return of 1:5, we feel that our production positively impacts the full life circle of a natural resource, from cradle to grave. By combining the All-in-One features such as being durable, strong, lightweight, water absorbent and recyclable, Leca® LWA actually benefits the environment, limiting resource requirements and improving our living and working conditions.

We believe that Leca® LWA has a positive effect on every stage of the product lifecycle from Production, Transport, Construction, Living to Recycling. This strong lightweight and inert aggregate can be used everywhere, and can be re-used / re-cycled - and can even be returned back to the Earth. We like to call it 'Borrowed from Nature'.

This is not just another nice story on sustainability, we are actually doing this!

Commitment to Sustainability

Our intermediate commitment is reducing the greenhouse gas emissions by 30% in 2025 followed by 50% reduction by 2030, achieving Carbon Neutrality by 2050. For that LECA will invest in clean processes, substituting the consumption of fossil fuels with green energy. At the same time, we intend to reduce the consumption of virgin materials in our operations and improving the circular economy with our customers and partners. To bring to You and to the Planet an even more sustainable product.

New Self-Sufficient Photovoltaic Facility in Manufacturing Plant in Portugal

As part of our global sustainability commitments, at our production plant in Avelar, Portugal, we are preparing to open a new facility, which converts light into electricity using semiconducting materials. This photovoltaic facility will self-sufficiently produce sustainable electricity for LECA’s manufacturing requirements. The key objective of this project is to annually reduce carbon dioxide emissions at an estimated 1,105 tons.

Interview with LECA Sustainable Specialist Ana Raquel Fernandes

The goals of Saint Gobain are filtered to all the companies, so the global goals for Leca International are the same. In this moment we need to translate that to goals per country and per plant and see how they can be applied and “fit to us” because we need to adapt them into our daily reality.

Reducing Green House Emissions

LECA is part of the Saint-Gobain Group which is committed in reducing greenhouse gas emissions and achieve Carbon Neutrality by 2050. We base our commitments on profound environmental analyses according to the GHG Protocol, which manage the greenhouse gas (GHG) emissions from operations, value chains and mitigation actions. This methodology allows us to analyze the emissions related to the direct as indirect emissions from production and supply chain emissions.
