Environmental technology company dedicated to combating microplastic pollution in aquatic environments. Their mission is to develop and deploy systems that intercept microplastics across key areas of emission and concentration, thereby safeguarding water quality, human health, and aquatic ecosystems.
WT

A pioneering clean energy company harnessing proprietary biorefinery technology to convert invasive aquatic biomass waste into renewable natural gas (RNG) and biofuels. By capturing methane emissions and utilizing CO₂, it advances a global carbon-negative model while restoring ecosystems and creating valuable circular economy byproducts.
WS

Newly synthesised desiccant to absorb H2O molecules from the atmosphere and then condense air molecules to produce potable water. Effective all climates and can uptake water from humidity levels as low as 10% humidity and at high temperatures approaching 40 centigrate. Powered not only with electricity, but also via biomass boilers and solar thermal batteries.
WA

This is the world's leading seaweed-based material technology company replacing single use plastics. This woman-owned firm is partnering with experts in regenerative aquaculture from Maine to New Zealand to expand the ‘blue economy’ with its proprietary resins. Made from easily compostable seaweed, their Ocean Blue straws, utensils and other products are already a favorite among some of the nation’s most famous chefs, restaurant chains and eco-chic hotels. Their new category of materials are “Designed to Disappear” and advancing our planet to a plastic-free, decarbonized future.
PN 34

This is an advanced materials start-up that upcycles food by-products to replace single-use plastics. Their proprietary technology uses a mixture of spent grains and agricultural waste, to produce a plant fibre material for rigid packaging. Made up of 100% organic waste, the material has received international certification to be home compostable and food contact safe from the US FDA and Singapore Food Agency.
P

Based in Ankaleshwar, Gujarat, India, this is a family-run, recycling business that converts low value plastic waste into quality sustainable materials for furniture, building and construction applications, advancing the circular economy in India and globally.
PN 6

This company is a developer of patented water-based technologies to chemically recycle waste plastics; convert heavy crude and bitumen into lighter, more valuable oil; and transform renewable oils into higher-value fuels or renewable chemicals. Their patented technology activates unique properties of water in a chemistry platform that operates at relatively low temperatures and cost, a game-changing novel approach that converts low-value feedstocks into 21st-century resources.
WTE

They have developed a sustainable mushroom based material as an alternative to polystyrene styrofoam and cardboard packaging. The material is customizable to any shape, size and surface finish. It is stronger than concrete pound for pound and is a better thermal insulator than fiberglass. It is fire resistant, water proof, 100% compostable, odorless, mold resistant and non-toxic.
PN 55

This company was established in 2005 to save London's decommissioned fire-hose, ones that had become too damaged to repair and were going to landfill. Today, their highly skilled craftspeople make beautifully designed bags and homeware from 15 different reclaimed materials. 50% of profits from the Fire-hose Collection go to The Fire Fighters Charity and 50% of profits from the Fire & Hide Collection go to Barefoot College International.
PN 143

Smart waste technologies streamline collection and recycling, maximizing resource recovery and minimizing landfill use. These solutions improve processing efficiency, promote sustainable infrastructure, and enable circular systems, addressing urgent challenges in urban waste management and resource conservation.
PN 77

Depolymerization technology restores plastics to their raw molecular forms, enabling infinite recycling without quality loss. This process reduces reliance on virgin materials, conserves resources, and advances circular manufacturing systems, tackling waste challenges in packaging and textiles.
P

Eco-friendly materials replace harmful alternatives, cutting carbon emissions while maintaining industrial performance. This technology reduces environmental footprints, supports renewable sourcing, and delivers scalable solutions for greener manufacturing, solving sustainability challenges across industries.
PN 75

Innovative recycling processes separate and reclaim fibers from discarded textiles, giving fabrics new life and reducing landfill waste. This closed-loop system addresses resource overuse and environmental damage, promoting sustainable fashion and circular economies at scale.
C

Advanced enzyme engineering decomposes polymers into reusable components, enabling endless recycling cycles and reducing landfill reliance. This technology lowers environmental impact, cuts production costs, and paves the way for sustainable material development, solving critical challenges in waste transformation.
PN 26

Enzyme-driven recycling technologies break down plastics into reusable building blocks, eliminating waste while preserving material quality. This scalable process reduces dependency on fossil fuels, supports biodegradable alternatives, and drives innovations for circular manufacturing, addressing global sustainability challenges.
