Improve the production of all valves and fittings for distribution and access to water, while helping to control consumption and preserve this scarce resource by limiting and preventing leaks.

Nidaplast Environnement is a French manufacturer specializing in innovative and sustainable solutions for water management and urban development. For over four decades, the company has been developing and producing high-performance materials designed to respond to the growing challenges of climate change, urbanization, and sustainable construction.

Our expertise covers a wide range of solutions that help cities, businesses, and communities build more resilient and eco-friendly infrastructures:

Stormwater management: Nidaplast designs and manufactures underground infiltration and retention basins. These modular systems enable effective control of rainwater flows, prevent flooding risks, and integrate seamlessly into urban or natural landscapes

• Permeable surfaces and parking areas: With our Nidagravel®, Nidagrass®, and Ocity® ranges, we offer durable, aesthetic, and eco-responsible solutions for permeable paving. These systems allow rainwater to infiltrate naturally into the ground, reducing runoff and helping fight soil sealing.
  • Nidagravel® stabilizes decorative gravel, ensuring a firm and durable surface.
  • Nidagrass® supports natural grass, creating green, reinforced surfaces suitable for parking and landscaping.
  • Ocity® is compatible with pavers, gravel, or natural grass, and can even combine these materials for mixed surfaces (pavers–gravel–grass), offering unique design flexibility.

• Lightweight backfills: Nidaplast lightweight fill solutions are used in landscaping and road construction. They provide high compressive strength while being up to 50 times lighter than traditional fill materials. This combination allows more flexible, stable, and sustainable designs for roads, embankments, and green spaces. Our Nidaplast RA range offers an additional advantage: it is specifically designed to manage water table rise and groundwater pressure, making the fill insensitive to water fluctuations and ensuring long-term performance even in challenging environments.

As a manufacturer, Nidaplast controls the entire production process, ensuring consistent quality, reliability, and performance of its materials. Our products are engineered for long-lasting durability and are continuously improved through innovation and research.

Driven by a strong commitment to sustainability and innovation, Nidaplast Environnement contributes to building infrastructures that combine technical efficiency with environmental responsibility. By integrating water management, permeability, and lightweight construction, we help shape greener cities and landscapes adapted to the challenges of tomorrow.

Committed to Sustainability and Continuous Improvement
Nidaplast integrates environmental responsibility at every stage of its activities. Certified ISO 14001, ISO 9001 and ISO 18001, we follow strict standards in environmental management, quality, and workplace safety. We are proud to hold the MoRe label (Mobilisé pour Recycler), which recognizes our commitment to using recycled raw materials, as well as the Coq Vert community label and an EcoVadis Bronze medal in 2024. Our new industrial site further strengthens this commitment, with optimized logistics flows, improved waste management, reduced energy consumption, and more efficient production equipment that lowers our environmental footprint.

1. WESTRAND presentation and history:

Westrand invented in 1993 the industrial odour removal profession based on neutralizing products.
Until then, only masking or over-smelling products existed.
Westrand produces and markets a very wide range of reagents (patented).
They are derived from a combination of natural and synthetic essential oils containing a mixture of aldehydes and ketones.

Westrand also design and install the engineering systems to diffuse these reagents.

We have 4 main sectors of activity:

• Garbage sector: household waste or chemical product incinerators, methane fermentations, non-hazardous waste storage facilities, sludge, and green waste composting, …
• Wastewater sector: wastewater treatment plants, gravity-fed sewers, lifting stations, lagoons, …
• Industry sector: Petrochemical, food industry, slaughtering, …
• Soil decontamination: old gas plants, chemical discharges, old refineries, old gas station, …

Westrand is recognized for its effectiveness and responsiveness.

A global company, Westrand is established in more than 25 countries with more than 1 500 references.

2. WESTRAND products:

1. Chemical reactions:

Our products are composed of natural and synthetic essential oils made up of mixtures of:

• Ketones

These mixtures neutralize by chemical reactions (see appendix) foul-smelling gases such as:

• Ammonia
• Amines
• Hydrogen sulphide
• Mercaptans
• Other

The use of our neutralizers ensures the decrease of 90 to 95% of the odour concentration.

2. Patents:

The main active principles used are covered by the following patents:

• French patent no. 2 599 257 of 29/05/1986
• Addition certificate no. 2 623 717 of 1/12/1987
