Houston VC invests in early stage California biodegradable plastics startup

Houston-based venture capital firm First Bight Ventures led a $5 million seed round for Encinitas, California-based startup Algenesis, a developer of biodegradable plastics.

Algenesis bills its patented Soleic technology as the world’s first renewable, high-performance, fully biodegradable, and backyard-compostable polyurethane made from plants and algae. Each year, 25 million tons of hard-to-recycle polyurethane are produced for the footwear, medical, and textile industries. Polyurethane, typically made from petroleum, usually ends up as landfill waste or environmental microplastics.

Algenesis says Soleic can biodegrade in compost within a matter of months and does not contain harmful PFAS chemicals found in other plastics.

Algenesis says the new funding will enable it to expand beyond soft-foam applications, such as midsoles and insoles for footwear, and into injection-molded products such as smartphone cases along with waterproof textiles.

Aside from First Bight Ventures, investors in the seed round are Singapore-based Circulate Capital, India-based MIH Capital, Chesapeake, Virginia-based Diamond Sports Group, and France-based Rhinoshield.

The investment comes on the heels of a $5 million grant Algenesis received from the U.S. Department of Energy to scale up production of biochemicals.

“To save our planet and ourselves, we must move away from petroleum-based plastics and toward bio-based alternatives. Algenesis is clearly at the forefront of making this possible,” says Veronica Wu, founder of First Bight Ventures.

First Bight, which launched in 2022, invests in early-stage startups working on synthetic biology.

“First Bight is investing to bring the best and the brightest — and most promising — synthetic biology startups from around the country to Houston,” Wu said last year.

Greentown Labs has named five climatech startups to its Go Make 2026 cohort, including one from Houston.

Greentown Go Make 2026 is in partnership with Shell Catalysts & Technologies and Technip Energies. Startups will be able to collaborate with leadership from Shell and Technip and have opportunities to work directly with their process engineering teams and develop potential partnerships, pilots and demonstrations, according to Greentown.

This year's manufacturing cohort focuses specifically on process technology and catalytic innovations, which, according to Greentown, have the potential to be a "critical enabler of the global energy transition." Greentown shares that 90 percent of chemical processes depend on catalysis, but traditional methods rely on fossil fuels and consume significant amounts of energy.

“Catalysis underpins the majority of industrial chemical processes, which together account for a significant share of global emissions, making it a critical lever for reducing carbon intensity while improving performance,” Georgina Campbell Flatter, CEO of Greentown, said in a news release. “Greentown Go Make 2026 is designed to close the gap between breakthrough innovation and industrial deployment. By connecting startups with Shell and Technip Energies’ technical expertise and global scale, we’re helping accelerate solutions that improve efficiency and drive industrial decarbonization.”

The five Greentown Go Make 2026 companies include:

  • Houston-based Biosimo, which makes scalable biochemicals from ethanol
  • Missouri-based Catalyxx, which transforms bioethanol into drop-in, cost-competitive, carbon-negative chemicals
  • Sydney, Australia-based HydGene Renewables, which produces low-carbon hydrogen and industrial chemicals from waste biomass
  • Switzerland-based TreaTech, which turns waste into renewable gas, water and minerals through catalytic hydrothermal gasification
  • California-based Unifuel, which has developed a chemical technology platform to make sustainable aviation fuel, renewable gasoline and other renewable chemicals

The cohort will be celebrated at a kickoff event in Houston at The Ion on June 9.

In addition to Greentown Go Make, Greentown also runs its Go Move (transportation), Go Energize (energy and electricity), Go Build (buildings), and Go Grow (food and agriculture) cohort-based programs. The climatech incubator announced its Go Build 2026 cohort in March. Read more here.
