Construction & demolition waste recyclers

Name: neustark
Price range: $

Boost your business while advancing sustainability: store CO₂ in recycled concrete and transform construction demolition materials (CDM) into climate solutions. Let’s explore a new promising market together.

neustark site for durable carbon removal at our partner Kästli in Rubigen, a construction and demolition waste recycler.

Neustark removes CO₂ from the atmosphere by storing CO₂ captured at biogas plants in mineral waste materials such as demolished concrete.

It’s a process that we’ve proven to be both commercially and ecologically viable – as the first player to do so worldwide. We have already launched 20+ storage sites and are scaling up quickly.

That’s where we need you.

Demolition concrete is our carbon ‘sink’. As a recycler, you have the construction demolition materials (CDM) – we have the technology to add on. Team up with us and turn the decarbonization of construction into an opportunity for your business.

We install our technology alongside your existing production process. Nothing is disrupted – it’s an add-on. And what’s more, it's a big value add-on for you: for your baseline, for your sustainability efforts, and for your future-proofing business model.

Play your part in decarbonizing the industry and team up with us today!

This is how we store CO₂

Storage sites at recycling plants

Construction material recyclers collect concrete and other waste materials and at their plants, they crush & sieve the material to prepare for further use.

And that’s where neustark comes into play: we inject CO₂ into the demolished concrete whilst these granules are being recycled.

Our technology accelerates the mineralization process, turning CO₂ into limestone – and thus permanently binding it to the demolished concrete.

Alongside the existing process

This all happens alongside the recycler’s existing processes, not disrupting the plant's operations.

We build our technology on site at the recycling plant, connecting our tech with your existing operations (see below for solution types).

The granules injected with CO₂ can be used as per usual process, for example, to build streets or other infrastructure, or to produce fresh recycled concrete.

Result: added value for all!

It’s a win-win-win: recyclers profit from an additional revenue stream that also helps their sustainability action.

Neustark can remove CO₂ from the atmosphere. Both businesses and the climate benefit.

Let's go on this pioneering journey, together.

Our carbon removal partners

Case study

Möckli Beton AG

Since September 2023, neustark's storage technology has been integrated into Swiss concrete recycler and producer Möckli Beton AG's production process. And have been permanently storing tonnes and tonnes of CO₂ every day since the plant went into operation.

Case study

HEIM Group

What started with a pilot project to mineralize CO₂ into recycled concrete to build a real estate development in Berlin, has led to operating the first commercial CO₂ storage facility in Germany. Since autumn 2023 neustark and the HEIM Group are removing CO₂ together.

So how does the process of working together look like?

Step 1

We determine the ecological and commercial potential based on the specific framework for your business.

Step 2

We validate the key assumption behind the calculated potential through a lab-scale test series. If needed, we validate those tests at a larger scale.

Step 3

Together, we design and implement a stationary solution that ideally fits into your existing infrastructure and processes.

Step 4

We construct the plant, and once ready, you take on ownership.

Step 5

You operate the plant, and neustark works with you to store many tonnes of CO₂ over the years!

FAQs

Neustark’s solution is based on the well-researched chemical process known as natural mineralization or carbonation. Our technology accelerates this process from over 1000 years to just a few hours while multiplying the average CO₂ uptake.

For more information, see How our solution works.
We have adaptable business models as well as product types, according to your needs.

In general, neustark constructs the storage technology at your plant. Once finished, the storage site belongs to you, the recycler. An initial, lump-sum investment to purchase the technology is needed. This investment is then counterbalanced by neustark paying you to utilize your storage site. Over the course of a few years, the initial investment is turned into profit for you.
We partner with biogas plant to filter out the CO₂ that is created during the plant’s production process. We then liquefy the captured CO₂ to then transport it to the nearby storage sites.
Today we store around 10 kg of CO₂ per ton of demolished concrete. We are of course continuously working on further optimizing this figure.
