• Spark Cleantech

  Led · Series A · Dec 2025

  Founded in 2022 out of CentraleSupélec laboratories, Spark Cleantech is a Paris-based deep-tech company aiming to slash emissions from energy-intensive sectors such as glassmaking, metallurgy, polymers and batteries. Its core product is a plug-in module that sits between an industrial site’s existing gas network and high-temperature burners, using proprietary pulsed plasmolysis to strip carbon from the fuel stream before combustion. The process yields two saleable, fully decarbonised outputs—hydrogen for heat and a solid carbon nanomaterial—while cutting CO₂ emissions by as much as 85 percent and multiplying the economic value of the input gas four-fold. The pulsed plasmolysis technology, initially invented at Stanford University and refined at CentraleSupélec, is now being piloted with major industrial customers across Europe. With fresh capital, the company plans to complete and operate its first full-scale production module, qualify its inaugural commercial carbon grades, and hire roughly 20 employees in commercial, engineering and R&D roles. Spark Cleantech positions itself as both an emissions-reduction solution provider and a supplier of high-value carbon additives for polymer and battery markets.

• Elemental Advanced Materials

  Led · Equity · Jun 2025

  Elemental Advanced Materials operates a patented, single-step manufacturing platform that transforms plastics, tank bottoms and gas by-products into high-purity carbon nanomaterials (including graphene and carbon nano-onions) and clean hydrogen. The company also recovers critical minerals from end-of-life electronics to support circularity in supply chains. Its carbon nanomaterials are sold for use in batteries, capacitors, electronics and to enhance durability, thermal and electrical conductivity, and EMI shielding in cement, resins, composites and lubricants while reducing embedded emissions. Elemental says the CO₂e-neutral process replaces toxic, resource-intensive legacy systems and supports sustainable industrial innovation. The recent funding will be used to scale production, expand capabilities to recover critical minerals from e-waste, and deploy the company’s low-carbon platform at commercial scale. Elemental is headquartered in Houston.

• Novoloop

  Led · Series B · Jun 2025

  Novoloop has developed a process that breaks down polyethylene waste into monomers and synthesizes higher-value thermoplastic polyurethane (TPU) branded as Lifecycled TPU. The company completed a demonstration plant test run capable of producing up to 70 metric tons per year and reports strong demand — "literally every time we make something, we’re sold out," CEO Miranda Wang said. Its material has been used by running-shoe maker On for the tread of the Cloudprime sneaker. Novoloop says the upcycled material is more expensive than virgin TPU but "within range." The firm has also added a business line mechanically recycling TPU factory scraps and adding performance enhancers to make recycled TPU perform more like virgin material. On the heels of the demo run, Novoloop is preparing plans for a larger commercial facility and is evaluating building alongside existing chemical plants to leverage land and utilities. Novoloop develops proprietary ATOD (Accelerated Thermal Oxidative Decomposition) chemistry to upcycle polyethylene and other plastic waste into high-performance chemicals and materials, including its first product Oistre, a thermoplastic polyurethane (TPU). The TPU targets durable applications such as shoes, apparel, sporting goods, electronics and automotive components and the company says its product can have up to a 46% smaller carbon footprint versus conventional TPUs. Founded in 2015 by Jeanny Yao and Miranda Wang, Novoloop plans to scale its chemical process above the 1 metric ton scale and to establish a feedstock pretreatment unit in California later this year to accelerate pilot customer deliveries. The startup has disclosed total funding of $24 million, including an $11 million Series A earlier in February and a $10 million Series A extension reported here. Strategic partners and investors are expected to support process development, feedstock sourcing and market access as the company moves toward commercialization. Novoloop emphasizes creating a circular economy for plastics by turning contaminated, low-grade post-consumer waste into commercially usable materials. Novoloop has developed a proprietary process called ATOD™ (Accelerated Thermal Oxidative Decomposition) to break down polyethylene into chemical building blocks that can be synthesized into high-performance products. Its first commercial product is Oistre™, a recycled thermoplastic polyurethane (TPU) aimed at footwear, apparel, sporting goods, automotive and electronics markets. The company says Oistre can have a carbon footprint up to 46% smaller than conventional TPUs. Novoloop was founded and is led by two scientists, Jeanny Yao and Miranda Wang, who have worked on the technology for over five years. The company is partnering with Bemis Associates for product applications such as seam tapes in high-performance outerwear. Novoloop positions itself to compete with incumbent TPU producers like BASF, Covestro, Lubrizol and Huntsman and to disrupt an industry where roughly 99% of TPUs are made from virgin fossil feedstocks.

• RepAir

  Led · Series A · Apr 2025

  RepAir Carbon develops a battery- and fuel-cell‑inspired direct air capture system that uses electricity to drive a reversible chemical reaction to remove CO2. Its reactor uses two electrodes separated by a membrane; a nickel‑based electrode with hydroxide attracts CO2, converting it into carbonate and bicarbonate ions that migrate to the opposite electrode and are released as CO2 for capture. The company says this electrically driven, reversible process allows regeneration while operating, reducing downtime compared with solvent‑heating approaches. RepAir claims its approach could lower capture costs to about $70–$80 per metric ton versus roughly $600 per ton estimated for other approaches. The technology is intended for both atmospheric capture and exhaust-stream capture from power plants and similar sources. RepAir is engaging with developers to integrate its system with gas turbines to cut emissions from data centers. RepAir Carbon Capture develops a modular direct air capture (DAC) system that captures carbon dioxide from ambient air using renewable electricity. Led by CEO Amir Shiner and founded in 2020, the company's design uses multiple cell stacks to enable modularity, scalability, and affordability. RepAir's technology is said to use roughly 70% less energy than conventional DAC systems. The system is engineered for gigaton-scale CO2 separation while targeting lower energy and capital intensity. The company plans to use recent funding to expand operations and continue development efforts. RepAir Carbon has adapted ideas from fuel cell technology to build a modular direct air capture (DAC) “cell” that uses an electrical current and a selective membrane to separate CO2 from ambient air. The company says its approach can consume up to three times less energy per tonne of CO2 captured and avoids the high temperatures and pressure differentials required by many existing DAC systems. RepAir emphasizes a lower CapEx, electrochemical, Lego‑like modular design intended to enable deployment at scale and placement next to intermittent renewables such as wind farms. The startup is focused on advancing and optimizing a TRL3 prototype as its next technical milestone. RepAir aims to develop the platform toward gigaton-scale capture and storage of greenhouse gases. The team includes co-founder and CEO Amir Shiner, co-founder and chairman Yehuda Borenstein, CTO Ben Achrai, PhD, and board member Yushan Yan, PhD; the company is Israel-based and currently funded by a recent seed round.
