Recycling and waste management
Each year, we actively look for ways to improve our procedures and reduce our environmental impact even further. We are maximising the reduction, recycling and recovery of waste in both process and packaging through the following initiatives:
Recycling of fibre cement waste
Recycling of products in the construction industry is becoming increasingly important as strict targets set by the EU Waste Directive require 70% of construction and demolition waste to be re-used, recycled or recovered by 2020. Fibre cement can help to achieve these waste targets because it can be fully recycled at the end of its lifetime.
Fibre cement product can become a valuable component of the Portland clinker raw meal. It can be ground down and used to replace limestone and shale in clinker production, essential ingredients for Portland cement, the most common type of cement used across the world.
- Remove 100% of the fibre cement waste
- Meets the 2008 EU Waste Directive
- Reduces the carbon footprint of fibre cement products
- Increases the sustainability of clinker production
- Improves the Life Cycle Assessment and Environmental Product Declaration of fibre cement products
- CO2 emissions cut from the reduction in the use of limestone by minimising the effects of quarrying and improving the environmental impact by energy reduction

We have installed a silt de-watering system which enables water to be recycled and minimises the use of borehole water.
The de-watered silt can be handled as a ‘solid’ and is disposed of at a local quarry, meeting the waste management conditions of the quarry operator licence. The silt is transported as ‘back loads’ to the quarry which optimises transport costs and reduces the environmental impact of haulage.
As a result of this system, the moisture control of the silt slurry has been reduced significantly with an approximate saving of water in excess of 2,000m3/per year. In addition rainwater harvesting is being used to recycle rain water for use in the production process.
Aggregates & raw materials
Our products provide no direct risk of pollution to either the air or water.
Stable and inert waste products can either be reused, recycled or (where not possible) used as bulk material for landscaping etc. All of the solid waste from our fibre cement sheets is recycled by a local cement works and re-used within the cement production process. This reduces the environmental impact of waste to landfill and also reduces raw material usage in the cement manufacturing process.
We also operate a scheme to make sure that crushed hardcore can be used as aggregate replacement in our concrete products. As well as saving valuable resources, this reduces our impact on local neighbourhoods and reduces the haulage of raw materials. The remainder of hard waste from production is sent for use in road construction rather than to landfill.
Packaging & Delivery
We pride ourselves with the efficiency of the distribution of our products and the quality of the product delivered to our customers.
On the roads we use eco-friendly, low-emission and fuel-efficient lorries that are regularly serviced. We also make sure that there is a return load for every trip where possible, to optimise vehicle usage.
The packaging used to protect the product during transit and storage on site or in the distribution yard is continually reviewed, and wherever possible reduced to lower the impact of waste without compromising quality and integrity.
Timber used in our pallets are sourced from FSC managed forests, and wherever possible, recyclable cardboard and plastics is used for banding, interleaves, bags and boxes.
Wherever possible, all our sites reduce, re-use or recycle waste, rather than send it to landfill. We’ve even installed a waste-to-energy power plant at one of our factories, converting all sorts of waste, from cement bags to irreparably damaged timber pallets, to heat.
Waste created during the manufacturing process is minimised, and wherever possible is re-used in the production of new products.
Additionally, at the end of their life, our tiles and slates can be recycled and used as aggregate in other concrete products and in cement production.
This reduces demand for quarrying of virgin material, reduces the amount of waste going to landfill in local areas near our sites and reduces energy consumption. All roof tiles are delivered on timber pallets manufactured from FSC certified sources, and we operate a returnable pallet scheme and we are saving around 1,000 tonnes of timber each and every year. Any pallets that are beyond repair are either chipped for recycling or fed into a waste-to-energy incinerator.
