Our technology makes two big problems smaller.
NX-Cast Innovations turns the plastic that the recycling system cannot use into better concrete and asphalt. Our mission is to make it easier for producers to offer lighter, longer-lasting, lower-carbon products without taking on new operational risk.
Who we are: We’re problem-solvers who have lived concrete and construction from the inside.
NX-Cast is a materials and product development company built by people with decades of experience in construction product development, mix design, and plant operations. That grounding drives everything we do. Our technologies are designed to work with the equipment, crews, and quality routines producers and contractors already rely on.
What we build: Solutions, not a single product:
Practical Ingenuity at Work
ReLite+: an engineered ecofiller made from difficult-to-recycle plastic.
The ECOS Optimization Platform: the way ReLite+ is put to work, using SCMs and other waste-derived materials to solve everyday producer problems.
The ECOS Alliance: the licensing network that carries the model to regional facilities.
ELCEMITE and our building products: the decades of invention behind the platform.
ReLite+ turns difficult-to-recycle plastic into an engineered ecofiller. The ECOS Optimization Platform uses the room it creates to bring in supplementary cementitious materials and other waste-derived materials so that producers can make lighter, longer-lasting, lower-carbon products with no green-up charge.
Two industries, one gap:
9 percent: Only about 9 percent of the world's plastic waste is recycled. The rest is incinerated, landfilled, or mismanaged. (OECD, 2019 data)
8 percent: Cement is responsible for about 8 percent of global CO2 emissions. (World Cement Association)
Both industries have worked hard on supply. What's missing is demand for a repurposed product. That is where we work.
What we do:
One platform, two parts:
ReLite+
An engineered ecofiller made from plastic that closed-loop recycling cannot economically absorb. That includes black plastics, Bakelite and other thermosets, PVC, and multilayer packaging. We do not melt it, and we do not extrude it.
The ECOS Optimization Platform
The way ReLite+ is put to work. ReLite+ creates headroom in the concrete mix. ECOS spends that headroom on practical fixes for the problems producers deal with every day, using supplementary cementitious materials and other waste-derived materials.

What producers get:
Built around the producer's list.
Lighter. More product on every truck, with a mix that still meets its specification.
Less cement per performance. Designed to help reduce the cement a mix needs.
More durable. Designed to help address brittleness, porosity, early thermal cracking, alkali-silica reaction, and sulfate attack.
No green-up charge. Better performance without a premium the customer will not pay.
No new equipment. Fits the batching and mixing plants producers already run.
Concrete and asphalt. One platform for both.
Recyclers: Recycle what can be recycled. Build with what cannot.
ReLite+ is for the residual plastic that has no resin buyer. It complements closed-loop recycling and does not compete with it. Concrete and asphalt do not buy virgin plastic, so nothing here displaces resin.
Facilities:
The next step is building the facilities.
The first processing facility is planned for the Mitchell area of Southwestern Ontario. Its job is to show a licensable model that recyclers and waste handlers can repeat in their own regions, giving concrete and asphalt producers a material they understand and want to include in their products.
Work with us: Three ways to work with us.
Producers
Trial ReLite+, license the platform, or join the ReLite+ Buyers Club for preferred access to supply and early access to new mix designs.
Plastics, recycling and waste handling
Give residual plastic a durable destination, or host a ReLite+ processing unit alongside your existing operation.
Funders, governments and brand owners
Help build the facilities that put a better material in producers' hands.

Where this comes from
Decades inside concrete and construction, applied to a bigger problem.
NX-Cast was built by people who have lived concrete and construction from the inside for decades. That experience in mix design, plant operations, and product development is why our technologies are designed to work with the equipment, crews, and quality routines producers already rely on.
Let's talk about what you are trying to build.

Our practical grounding drives everything NX‑Cast brings to market. From advanced lightweight composites and cement-lean systems to the ReLite+ ecofiller platform and Buyers Club model, each innovation is engineered for real-world plant conditions, reducing cement demand, lowering unit weight, improving durability, and transforming difficult-to-recycle IC&I plastics into controlled ingredients for concrete and other cementitious products.
