Homogeneous catalysts in chemical manufacturing enhance efficiency but can only be used once due to stability issues, increasing costs. Additionally, chemical process waste poses environmental and financial management challenges. High costs also stem from energy, raw materials, and technology needs. These factors highlight the industry’s urgency for sustainable and cost-effective practices.
DUDE CHEM addresses these challenges of chemical manufacturing by developing greener active pharmaceutical ingredients (APIs) and intermediates with its unique small molecule recipes that reduce the cost of goods sold (COGS) by at least 10% for innovative and generic APIs.
The startup meticulously assesses sustainability and synthesis routes to enhance process efficiency through optimization and rigorous analysis. It helps in high product quality and sustainability.
One of the DUDE CHEM sustainability methods can reduce catalyst costs by up to 82% in recovering expensive catalysts like chiral using cost-effective and accessible solvents like water rather than licensed “designer surfactants” for conducting reactions.
The market-validated and patented green tech toolbox of this startup offers cost-competitive chemical compounds that can reduce average CO2 emissions by 38%.
Co-founder and CEO Sonja Jost is leading this startup with a team of expert executives. She has experience with R&D project lead roles and is the CEO of DexLeChem GmbH. Jost holds a Master’s degree in chemistry from the Institute of Chemistry at the University of Technology Berlin and is Vice president of CCI Berlin.
DUDE CHEM has raised €6.5M in its latest seed funding round on Feb 7, 2024. B2ventures (BTov Partners) and Vorwerk Ventures were the lead investors in this round.
2. Ayas Renewables Converting Vegetables into Bio-renewable Chemicals
| Founding Year | 2015 |
| Headquarters | Alabama, United States |
| Total Funding Amount | $7.7M |
| Last Funding Round/Amount | Series A/- |

Existing petrochemical propylene glycol is derived from fossil fuels, contributing to carbon emissions and the depletion of non-renewable resources. It also causes environmental pollution from its production and use. Health concerns related to exposure and its use in products need a shift towards more sustainable, bio-based alternatives. Also, sustainable (green) chemical production faces challenges, including high costs of green technologies, reliance on non-renewable resources, and environmental impacts of waste and emissions.
Ayas Renewables tackles these challenges by converting vegetable and tallow processing byproducts into Bio-renewable chemicals.
The startup produces 99.9% pure, US Pharma Grade Propylene Glycol from 100% natural bio-based feedstocks like glycerin and sorbitol. It offers a biodegradable, FDA-approved, and cost-competitive alternative to petrochemicals in all markets.
Ayas Renewables’ proprietary process is in the second-generation vapor phase. The low-cost process has a low-temperature, low-pressure, hazardous acid, and exotic catalysts-free nature. With the same or less cost, the startup offers all markets the opportunity to replace petrochemical propylene glycol with a 100% bio-renewable sustainable alternative.
The startup is led by CEO Joe McGrail, who has 21+ years of experience in president and MD roles. Ayas Renewables raised a Series A round on Aug 22, 2022.
