Pam Building, A KEY PLAYER IN THE CIRCULAR ECONOMY
More than a third of the world’s gas emissions and resource consumption can be linked to construction and the construction industry. This is in a context where the population is set to double in the next 30 years.
It is therefore necessary to significantly reduce the resource intensity of our buildings, if we want this growth to be compatible with the planet. This implies acting voluntarily both when buildings are designed and at the end of their life to ensure the waste is properly reused or recycled, and also throughout the entire life of buildings to maximise their use. Sustainable construction is a major worldwide trend.
The preservation of natural resources is a major societal challenge, especially for the construction sector, which is a major consumer of raw materials and energy. Pam Building evacuation systems are a responsible and sustainable choice, respectful of natural resources and people.

Pam Building's achievements
We have implemented all key elements of our strategy within our business. Thanks to these choices and investments within our Bayard and Telford plants we have already made great progress.
Focus on water: recent renovation of our water recovery basin in Bayard’s plant.
It is a substantial but environmentally beneficial project, which was completed in 2020 at the Bayard site. The works included the waterproofing of both the lagoons and water recovery basins. Once the waterproofing of the basins was complete, a pipe was installed to send the water from the lagoons to the pump room supplying the casting machines. Finally, the last stage consisted of evacuating the soil to an approved center. The benefits of this work are twofold: it considerably reduces the site's water consumption (we aim to halve the water consumption thanks to this), and it also guarantees the preservation of our environment and the quality of the water tables. They are in line with the sustainable development actions already carried out by our team at Bayard.
Focus on CO2 : the choice of a 100% renewable power sourcing.
Our plant in Telford made the choice to contract with the supplier SmartestEnergy in 2015, procuring us 100% renewable electricity for our electric furnace.

A cast iron pipe gives our waste a second life
In order to contribute to the preservation of natural resources, Pam Building’s molten iron is produced by recycling cast iron and ferrous products. Unlike plastics, it can be completely and systematically recycled at the end of its life. Pam Building’s drainage solutions can be recycled without any deterioration of their properties.
The product’s life cycle is also first-class in terms of environmentally-friendly logistics, long-lasting functionality (up to 70 years without compromising the mechanical properties), low maintenance costs and commercially beneficial recycling.

Fully recyclable indefinitely without losing any of its properties and made from recycled content*
For the standard S range, recycled content is 99% with 11.5% pre-consumer** & 87.5% post-consumer*** according to ISO 14021: 1999.
Nothing is wasted: everything is recycled
Cast iron pipe systems are based on the principle of modular ranges of removable components. Their mechanical assemblies are reversible.
You can change your mind today or even tomorrow. When pipe systems are disassembled or modified, these components can be reused, which cuts down on waste dumping.
*Recycled content: proportion, by mass, of recycled material in a product or packaging. Only pre-consumer and post-consumer materials shall be considered recycled content.
** Pre-consumer material: material diverted from the waste stream during a manufacturing process. This excludes the reuse of materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it.
*** Post-consumer material: material generated by households or commercial, industrial and institutional facilities in their role as end users of the product which can no longer be used for its intended purpose.

Organised and numerous actors in the recycling channel
The recycling channel exists: collector network and recovery stream is existing and working!
We work with local supply for scrap (<125 km from the plant) to reduced economic and transport costs.
Following ISO 14021:1999 and LEED V4 criteria we can provide a recycled content declaration for our products.

Life Cycle Assessment
Life Cycle Assessment: a rigorous tool for assessing the environmental impacts of our products.
We apply rigorous Life Cycle Assessment (LCA) tools to analyze our environmental footprint across multiple indicators: resource consumption, air and water emissions, energy usage, and carbon output. All assessments are based on international standard ISO 14040 and 14044.
- Multi-criteria: raw material sourcing, emissions, water use
- Multi-step: “cradle-to-gate” and “cradle-to-grave”
- Verified by third-party experts and auditors
This methodology helps us refine our design, production, and logistics to offer measurable environmental advantages to our clients and partners.

Discover how Pam Building's solutions can contribute to the international labels
The product’s life cycle is also first-class in terms of environmentally-friendly logistics, long-lasting functionality (up to 70 years without compromising the mechanical properties), low maintenance costs and worthwhile recycling.
Protecting the environment means understanding our products’ complete life cycle which helps us focus on areas for improvement, so we can significantly reduce our impact on the environment. This is the main route through which we can have a positive impact.

In 2020, we published an Environmental Product Declaration (EPD) covering our Standard and Plus wastewater and rainwater product ranges. This EPD meets both ISO 21930 and French standard NF P 01-010 requirements.
We integrate Efficient Design principles in every step:
- Reducing material use across small and large items
- Optimizing shapes for better mechanical behavior
- Extending product lifespan to avoid early replacement
This guarantees that our drainage solutions meet the expectations of the most demanding industries.
EPD for S range
