Our Portfolio

Our Climate Tech venture portfolio

Image Pattern Project are addressing overproduction in the fashion industry with an AI-driven supply chain and digital twin service for made-to-order garment manufacturing

The following startups have been launched and invested in by Carbon13’s Venture Builder and Venture Launchpad.

Each venture is solving the climate emergency, with the potential to mitigate CO₂e emissions by at least 10 million tonnes per annum when at scale.

Deep Blue Biotech

Deep Blue Biotech

We believe in the power of synthetic biology to decarbonize many of our everyday chemicals. This will present a new and essential alternative to address the current climate crisis. By recreating the building blocks of our everyday economy, we will create the multiplier effect that we need now to make a real impact faster.

Cocoon

Cocoon

To decarbonise the world, we are going to have to build a lot more. This means we will need more steel and cement over the next 40 years than ever before. However, these two materials represent 15% of global emissions. We’re capturing CO₂ into industrial waste and upcycling this into a green cement alternative to decarbonise the steel and cement industries. This mineralisation process has been the focus of our Chief Scientist Officer’s research and we’re now commercialising it at scale.

Danu Robotics

Danu Robotics

Danu Robotics is a team of dedicated engineers working together to develop advanced AI and robotic solutions for the benefit of the environment. Currently, we are developing the world’s first AI powered high-performance robotic sorting system that has the potential to fully automate the entire manual waste sorting process at any recycling facility regardless of its size, its current technology level and location.

Natural Building Systems

Natural Building Systems

Natural Building Systems has developed a carbon-negative modular system for sustainable construction. Using digital tools, they manufacture structural insulated panels (SIPs) with advanced bio-composites. The SIPs form an integrated ‘kit of parts’ analogous to flat pack furniture, delivered and rapidly assembled using non-specialist labour. Designed for disassembly and adaptation, their system reduces in-use carbon impacts by allowing zero waste alterations and re-use, and reduced operational carbon through improved energy efficiency, climate resilience and indoor air quality. The manufacturing process is energy-efficient and highly scalable.

Vundahaus

Vundahaus

VundaHaus is making homes Vundaful! They are driving the decarbonisation of homes by industrialising the insulation process. Their prefabricated insulation kit can be installed faster than traditional methods and at a fraction of the cost of other off-site solutions. Combining 3D scanning, automated design and efficient off-site manufacture, they will increase the productivity of installer partners and drive down costs for property owners, enabling retrofit at scale.

Zori Tex

Zori Tex

Zori Tex’s mission is to eliminate textile waste to landfill and incineration by innovating in technologies that unlock the value of circular textiles, enabling closed loop textile recycling to rapidly scale. Their solution uses AI driven vision to optimise sorting textile waste by fibre type, integrated with a traceability platform , trading and data analytics.

Circular11

Circular11

Circular11 turns low-grade plastic waste into building materials and outdoor construction timber. By combining composite material technology with an innovative process control system, they are creating a functional material, from, and so an end-market for, the cross-contaminated and film-based plastic streams that make up 60% of global plastic waste. At the same-time, they are providing the materials for a zero-carbon built environment.

Phoenix Carbon

Phoenix Carbon

Phoenix Carbon is a composite recycling process, enabling a circular economy for the sustainable use of carbon fiber as a commodity and product across Aero, Auto, Marine and Leisure sectors. This reduces emissions by 87% compared to virgin carbon fiber.​

Nium

Nium

Nium eliminates emissions by delivering hydrogen as a more efficient energy vector. Their novel nanotechnology revolutionises the Haber-Bosch process and enables the synthesis of truly green ammonia.​

With two patents filed, Nium helps build the infrastructure and network for a cleaner future of food and fuel.

17Cicada

17Cicada

17Cicada is developing a bacterial platform for the production of chemicals from waste. Their first-of-its-kind technology produces building blocks for bioplastics, textiles, cosmetic and more. The low-hanging fruit is FDCA, a monomer which can replace terephthalic acid which comes from crude oil and is used to manufacture mainstay plastics.​

BioZeroc

BioZeroc

BioZeroc is decarbonising the construction industry by creating carbon-negative construction materials from waste products.​

Their expertise in bio- and nanotech has allowed them to bypass the need for cement in concrete manufacturing, at minimal cost to producers and the environment.

Materials Nexus

Materials Nexus

Materials Nexus is seeking to revolutionise how new low-carbon sustainable materials are discovered and developed. Typically, getting a new sustainable material to market takes 20 years but this can be markedly reduced using their technology. Their initial focus is on novel alloys and ceramics, leading with high-strength, light-weight recyclable alloys to replace steel in the automotive industry, that promise up to 20% increase in fuel/battery efficiency​.
