The Gap Between Media Attention and the Technical Reality of Recycling Startups
A leading consumer goods company was exploring investment opportunities in recycling technology startups but faced challenges in validating their credibility.
Startups in the sector often receive media attention for funding rounds, sustainability claims, and innovative business models. However, much of the available literature focuses on financial growth and industry recognition rather than technical feasibility and operational stability.
The company sought a structured technical due diligence process to avoid investing in startups with unproven technology or unsustainable business models.
A 4-Pillar Due Diligence Model to Evaluate the Most Promising Recycling Tech Startups
A comprehensive due diligence framework was designed to analyze startups across four critical pillars:
- Technical Capability – Evaluating the robustness and differentiation of the technology.
- Business Viability – Assessing scalability, regulatory readiness, and commercialization potential.
- Financial Stability – Analyzing funding sources, profitability, and investor backing.
- Sustainability Impact – Examining carbon footprint, waste reduction, and regulatory compliance.
Within this structured approach, startups were evaluated on:
- Company Setup – Founding team expertise, leadership background, and track record in successful ventures.
- Geographical Presence – Key operational hubs, supply chain dependencies, and market reach.
- Technology Strength – Differentiation from competitors and alignment with industry needs.
- IP Protection – Patent filings, ownership, and licensing potential.
- Regulatory & Commercial Readiness – Compliance with industry standards and ability to scale production.
- Sustainability Credentials – Verified environmental impact, including GHG emissions and material efficiency.
This evaluation gave a list of the top 10 startups demonstrating strong performance across these key criteria.
Research Process- How GreyB Help?
Despite bold public claims, gaps remained in verifying the startups’ technology and sustainability. To address this, GreyB took two key steps:
Note: We’ll take different examples to dive into these steps for confidentiality reasons.
1. Validating Startups’ Scientific Claims Through Patent and Research Analysis
Startups often promote sustainability innovations, but the real question is whether the science supports their claims. For instance, when evaluating waterless cosmetics startups, we focused on Lush Cosmetics, a brand known for its eco-friendly, packaging-free products. While Lush marketed its waterless formulations, its marketing materials lacked clear technical details on how it achieved this. Instead of relying on promotional content, we conducted an in-depth patent and scientific literature analysis.

Our research revealed that Lush’s waterless technology wasn’t patented under their own name but under a different entity. This disclosure provided detailed insights into the specific formulations and ingredients enabling their waterless products. This gave our client deeper insights into Lush’s innovation beyond what public sources provided.
2. How Founders’ Claims Hold Up in One-on-One Conversations
Even well-researched literature can sometimes be misleading, leading to incorrect investment decisions. When analyzing carbon capture startups, we looked into Aqualung, a company gaining attention for its CO₂ capture technology. Online sources suggested that Aqualung’s process relied heavily on external water usage, raising sustainability concerns due to excessive water consumption.

To verify this, we interviewed Aqualung’s leadership team to gain firsthand insights into their process. It was revealed that Aqualung does not require external water sources, contrary to the online claims. Instead, it repurposes water naturally present in flue gases, making it a more sustainable solution than previously assumed. This clarity helped our client recognize Aqualung’s true innovation in carbon capture.
