Manufacturing Leca Lightweight Expanded Clay in a kiln

Simple ideas often last longer. LECA® LWA is basically made of freshly excavated clay, and produced through pre-treatment and high temperatures. 1m3 of fresh clay produces 5m3 of durable, natural aggregate. To be used in anything from flower pots to structural concrete bridge elements in harsh Northern seas. Focus on a resourcefully efficient production process is always maintained with the attention on producing as little waste as possible in the process. Strict quality control is in place in all our production plants to deliver high quality products with minimal environmental impact.


A Look at Leca LWA Production

100% CLAY, 100% NATURAL PRODUCT

Simple ideas often last longer. Leca Lightweight Expanded Clay Aggregate is made from fresh clay, and produced through pre-treatment and high temperatures1m3 of fresh clay produces 5m3 of durable, natural aggregate.

INTELLIGENT SOURCES OF ENERGY

In addition to clay, the small, strong Leca clay pellet consists of a range of different replacement products, which helps to preserve the natural raw material.

At the factory in Hinge, Denmark, liquid waste fuels from the pharmaceutical industry, mainly Novo Nordisk, are used in addition to coal. The liquid fuels primarily consist of water and solvents
