User Profile

The Closed Loop Partners investment platform is focused on building companies that are a key part of the developing circular economy, with a primary focus on innovative packaging material and design and advanced recycling systems and technologies. The team utilizes a unique network of corporate investors, foundation partnerships, municipal relationships, and university affiliations to create competitive advantages for portfolio companies.

The platform consists of three pillars:
  • Closed Loop Foundation researches and incubates business models that build markets and roadmaps to improve environmental outcomes.
  • Closed Loop Ventures invests in commercializing innovation across the product lifecycle – from material innovation and design to reuse and recycling.
  • Closed Loop Fund is a $100m debt fund that invests in scaling recycling through municipal infrastructure, private companies, materials and packaging.

Closed Loop Ventures invests in companies that are ready to commercialize a business that can turn waste from a cost into profit for the public and private sectors. For every ton of waste diverted from landfill and into recycling streams, on average, cities save $50, create 10 jobs and reduce a ton of greenhouse gas emissions.

By 2025, Closed Loop Fund aims to eliminate more than 50 million tons of greenhouse gas, divert more than 20 million cumulative tons of waste from landfills, and create more than 20,000 local jobs around the United States.


Closed Loop Partners uses IRIS metrics to standardize how it tracks impact across our portfolio of grants, equity investments, and loans.
