At Fonderie Mécanique Lensoise (FML), we believe a responsible industry is essential to safeguard our planet’s future. That is why we have integrated a comprehensive environmental approach into all our activities, from manufacturing to logistics, including energy and recycling.
Manufacturing
Eco-friendly
We constantly rethink our manufacturing processes to reduce our ecological footprint.
Material recycling
All our metal waste (bronze, brass, other metals) is sorted, shredded, and melted down to be reused.
Eco-friendly cleaning
Since 2024, we have been using a biological fountain to clean our parts and tools in a highly efficient, economical, and environmentally friendly way. This solvent-free process relies on a neutral pH solution and microorganisms to remove dirt without generating waste.



Reduction of absorbent waste
With our eco-friendly absorbent recycler, we recover, reuse, and recycle contaminated absorbents used during spills, significantly reducing our industrial waste.
Optimization
Of energy consumption
We have taken concrete actions to reduce our energy consumption:
LED lighting
All our facilities, from the offices to the foundry, are equipped with LED strips and bulbs, which are much more energy-efficient.
Streamlining of processes
The meltings in the foundry are grouped together to optimize gas usage.
Building optimization
We have renovated our facilities to minimize energy losses and improve overall energy efficiency.

Commitment
In sustainable logistics
Transportation is a key stage where we ensure to minimize our environmental impact.
Consolidated shipments
We consolidate orders to reduce the number of trips while meeting customer deadlines.
Responsible carriers
Our transportation partners are selected for their commitment to reducing CO₂ emissions.
Raising awareness
And digitization
We integrate eco-friendly practices even in our interactions with our partners and clients:
Reduction of printing
Between 2021 and 2023, we reduced our printing by 50% through the digitization of documents (quotes, invoices, catalogs, etc.). We will continue this approach in 2025 with the digitization of documents related to purchases (purchase orders, delivery notes, invoices, etc.).
Eco-friendly materials
Our catalogs are printed on 100% recycled, unbleached paper, certified PEFC, with biodegradable vegetable-based inks. Furthermore, their printing and finishing are entirely carried out in France.

Support for
Local and associative initiatives
Our approach goes beyond the environment: we collaborate with local associations to combine ecology and solidarity.
Partnerships with La Vie Active
We entrust the maintenance of our outdoor areas to this association, allowing workers with disabilities to integrate into professional life.
Solidarity recycling
Our used paper and catalogs are collected to fund operations for children with microtia, through the association Une Oreille de Cœur.
Animal rights advocacy
We are deeply sensitive to animal welfare and firmly believe that every living being deserves to be treated with respect and compassion. That’s why we actively support the Vermelles shelter, which works tirelessly for the well-being of abandoned and mistreated animals. Through our contribution, we hope to improve their living conditions and encourage their adoption.
Ergonomics
At work
The well-being of our teams is at the heart of our priorities.
In 2024, we invested in lift tables and bar carriers to improve workplace ergonomics and safeguard our employees’ health.
Respect
sanitary and environmental standards
All our products intended for drinking water supply comply with strict standards to ensure the protection of human health and the environment.
standard 4MS :
Our metals (bronze, brass) comply with the 4MS standard, limiting impurities and ensuring the Sanitary Conformity Certificate (ACS) for all our products in contact with drinking water.

Towards
a greener future
Our environmental approach is a daily priority and is constantly evolving. We invest in innovative technologies to combine industrial performance with environmental respect. At FML, we are convinced that every action, big or small, contributes to a more sustainable world.
