Composting companies see the highest average growth rates in the waste management industry by a long shot, in both the public and private markets. This is the result of several key factors converging:

• New environmental regulations are increasingly popping up at the state and locality level banning food and organic waste from landfills.  

• Consumer demand is shifting. Interest in organic food, home gardening, and sustainable landscaping saw a boost during the pandemic, and it has continued to grow.  

• Government support and infrastructure for composting programs are growing to accommodate evolving regulations and shifting consumer sentiment.

• Technology such as smart sensors, robotics, and processing efficiency solutions are making compost processing operations more effective and easier to scale.

• Companies in the CPG industry are increasingly seeking compostable alternatives to plastic packaging.

Composting companies also tend to see the highest average margins out of the sectors analyzed in the PE Playbook: Waste Management. Diverting organic waste from landfills reduces disposal fees for composting companies and their clients. Additionally, the natural decomposition involved in composting requires less energy than traditional waste processing, lowering processing costs.
