About 400 million tons of plastic are produced annually, however lower than 10% is recycled, with many of the relaxation ending up incinerated or in landfills. One purpose is that it’s troublesome for typical recycling processes to deal with contaminated plastics, like these which might be made up of a number of several types of plastics, mixed with different supplies or simply plain soiled. DePoly, a deep tech startup, has developed a course of that’s ready to sort out complicated plastic streams and switch plastics again into uncooked materials with out affecting high quality. The Swiss-based startup introduced at present it has raised $13.8 million in seed funding.
The spherical was co-led by BASF Venture Capital and Wingman Ventures, with participation from different traders like Beiersdorf, Infinity Recycling, CIECH Ventures and Angel Invest.
DePoly’s chemical recycling tech converts all PET plastics and polyester textiles again into their fundamental uncooked chemical parts, that are then bought again to the business to make new objects. DePoly says objects made from its uncooked materials are virgin-quality.
The firm presently operates a pilot plant that may course of 50 tons per 12 months of complicated PET or polyester plastic streams. It serves industries together with post-consumer packaging, textiles, trend and post-industrial streams. DePoly is constructing a showcase plant with a capability of 500 tons to display its tech at industrial scale, and already has 5 clients, ranging from quick trend manufacturers, sporting good manufacturers and packaging customers to resin producers.
DePoly was based in 2020 by CEO Samantha Anderson, CTO Bardiya Valizadeh and CSO Christopher Ireland, and now has a staff of 13 individuals. In the years earlier than launching DePoly, the three moved to Switzerland to work on their PhDs and post-docs. Anderson informed Ztoog that there have been numerous articles being revealed about points like microplastics in individuals, rising plastic patches in the ocean and animals washing up on shore with microplastics in their stomachs.

“For us, all this was quite alarming, particularly that companies seemed not to care about solving the problem now, not in 10 to 15 years,” Anderson stated. “So we decided that we wanted to tackle the plastic problem, using chemistry and the skills we had developed during our degrees, with the aim of if we could make it work, to spin a company out and tackle the problem faster than others were moving.”
Conventional plastic recycling means issues like bottles and meals packaging product of PET and different plastics are introduced to a recycling facility, then sorted into colours, cleaned, melted and became rPET pellets. But if they’re too soiled, blended with different plastics or in cloth or fiber kind, they often get incinerated or dumped right into a landfill, Anderson stated. There are additionally limits to what may be recycled due to well being and meals security requirements, which suggests the vast majority of plastic produced is destroyed or thrown away, and new plastic has to be made from crude oil.
DePloy’s chemical recycling tech operates at room temperature and normal stress, and doesn’t want plastics and supplies to be washed, pre-sorted, pre-melted or separated. This means it may be used to recycle PET and polyester that don’t make it into typical recycling programs, together with blended plastics, blended colours, soiled plastic waste streams, materials and fibers. PET is transformed again into PTA and MEG, its unique two monomers.
Anderson defined that DePoly has a B2B mannequin, connecting customers of complicated plastic waste, like blended polyesters, multilayered PET objects or PET objects which might be too soiled or chemically contaminated to be launched into the mechanical recycling course of, with individuals who produce virgin high quality PET objects from oil due to restricted accessibility to sustainable chemical compounds like PTA and MEG. DePoly’s tech permits one aspect to do away with PET and different plastic waste, and the opposite aspect (or the producers) to have entry to the unique, sustainable chemical compounds that make up these objects, making a round economic system for plastics.
DePoly also can do content material restoration. For instance, it may possibly get well PP or cotton from PP/PET combos or cotton/polyester blends. Anderson stated that is due to the low temperature of its system, as a result of it doesn’t soften polymers. The startup can be scaling tech for polyurethanes (PU), polylactic acid (PLA) and comparable polymers like PBT.
As an instance of how DePoly’s chemical recycling course of has been used, Anderson stated its labored with clients in the sporting items business which have polyurethane blended polyester objects. The polyurethane content material means these objects would often be discarded, however DePoly is in a position to totally recycle them and is now scaling its tech to get well the polyurethane portion.
Anderson cites startups Carbios, Gr3n and Ioniqua as different startups which might be doing comparable work with plastics, and says she thinks “the tech they’ve developed is really neat.” The fundamental manner DePoly differentiates is the response that happens throughout its recycling course of, the product output in Ioniqua’s case, the temperature required for the response and the contamination threshold allowed. “In our case, we’re lower temperature, produce the same monomers that make up PET and to our understanding have a higher contamination threshold versus others.”
In an announcement concerning the funding, Wingman Ventures principal Antonia Albert stated, “We are extremely proud to support DePoly since day one on their journey to tackle this planetary crisis to clean our oceans and landfills from plastic waste and to welcome leading investors from the chemicals, recycling, climate- and deep tech space on board to build the global leader for the sustainable plastics recycling.”
