Carbon13 Cohort 3 Showcase Day

Ventures launched and funded by Carbon13’s Venture Builder showcase their innovative startups at the Cambridge Union.

Upcoming dates:

6 December 2022 –  2pm – 6pm GMT

About this Event

Welcome to Cohort 3’s Showcase Day at the Cambridge Union: join us and find out what 10 million tonnes CO2e reduction yearly really looks like.

12 startups with transformative solutions for decarbonisation and carbon capture will be showcasing to the Carbon13 community. With solutions ranging from the use of bacteria to manufacture raw materials from polymers, through precision fermentation, to carbon-negative battery recycling, come support them and celebrate their innovation with us.

Each startup is part of the Carbon13 Venture Builder and has received intensive support to tackle the biggest challenges in Net Zero and launch highly scalable ventures. 

Each pitch will include an open Q&A. The event will culminate in a drinks reception where you can meet our team, experts and founders, give feedback on projects (because your expertise is always welcome!), and become part of our mission to save the planet.

Showcase Schedule: 


1300: Arrive at Cambridge Union


1345: Take Seats


1400: Welcome from Carbon13


1430-1445: Preoptima

A generative-based technology to drive low carbon design of building assets.
Preoptima uses AI with unique proprietary datasets to drive carbon reduction of hundreds of megatons at global scale, by achieving high-accuracy carbon calculations from very early on, prior to design decisions.


1445-1500: Open Hydro

Enabling climate finance to hydropower assets by standardising the reporting information for benchmarking assets and driving emission reduction activities.
They will replace the slow process of data collection with a targeted solution that will expand into additional renewable energy markets.


1500-1515: Sun Bear Bioworks

Sun Bear Bioworks is reimagining farming with precision fermentation to produce healthier and sustainable everyday ingredients for the food, cosmetics, medical and fuel industries. They will develop a palm oil alternative, without the sustainability issues and with a healthier chemical profile and use agricultural waste as their feedstock rather than sugar, to farm oils, proteins and fuels more sustainably.


1515-1530: Sunjul

Sunjul is the first impartial decision-making platform designed specifically for agrivoltaics, incorporating geospatial data on crop yield, water use, soil erosion and solar energy generation over the 30-year life of any project. This SaaS platform will simplify data, shrink planning and development times and de-risk projects by providing clear measurements for the project life. It saves time and money, increases food security and enables the transition to renewable energy.


1530-1545: Nium

Nium uses nanotechnology to decarbonise chemistry. They are starting with the #1 industrial chemical polluter: Ammonia. With two patents secured, Nium helps build the infrastructure and network for a cleaner future of food and fuel.


1545 – 1600: Comfort Break


1600-1615: 17Cicada

17Cicada is enabling the switch to petroleum-free plastics by using bacteria to manufacture raw materials for polymers.


1615-1630: ReScope

lmproving the way investors understand, quantify and report on climate risk. ReScope are developing the next generation scenario analysis tool that will enable investors to improve the resilience of their assets, develop more sustainable investment strategies, as well as respond to climate risk reporting mandates.


1630-1645: Circular 11

Circular11 turns low-grade plastic waste into building materials and home products. In doing so, they create an end-market for the contaminated and film-based plastics that make up between 50 and 80% of global packaging waste.



Mortar IO is supercharging and de-risking retrofits. The breakthrough technology  helps organisations understand how to achieve Net Zero for entire portfolios in minutes, rather than months.


1700-1715: The Battery Recycling Company (TBRC)

TBRC is a deep tech startup, aiming to build the world’s first carbon negative closed-loop battery recycling system by the end of 2023 – enabling the re-use of over 95% of materials currently used in EV Lithium-ion batteries. Their proprietary technologies ensure quality supply for future battery demand, reduced costs of battery production and turn battery production into a net-zero industry, helping companies and the world to surpass their climate targets.


1715-1730: Zoritex

Zori tex’s mission is to eliminate textile waste to landfill and incineration. Their solution assesses the fibre composition of textile waste using a combination of hardware and data analytics (as 40% of labelling can be incorrect) to create a marketplace for the sorted textile waste feedstocks. This unlocks the value of circular textiles and enabling the new textile-to-textile recycling market to rapidly scale.


1730-1745: Elaniti

Elaniti aims to improve crop health and yield by optimising the soil microbiome, through an increase in beneficial microbial activity and biodiversity. Helping companies measure their true impact on soil biodiversity, reduce destructive practices, and increase nutritional density in their products.


1745: Closing remarks


1800: A festive reception with drinks and canapes; a chance to network with the founders, Carbon13 Entrepreneurs in Residence and community.
