Gritty - A Philly Collab

Bennett Compost and Remark Glass/Bottle Underground came together in 2021 as collaborators on a project spearheaded by OLIN Studios using crushed glass and food compost as components of a soil blend. Circular Soil was used alongside traditional soil mediums via several plantings throughout Philadelphia as part of a grant awarded to OLIN to test it’s validity.

In 2024 this blend was commissioned by The University of Pennsylvania for a street tree planting. Bennett Compost provided the compost as well as the soil blending and began talking with Bottle Underground about making a separate blend using our products (glass and compost) that could be sold to a Philadelphia grower. Gritty was born.

Use to grow your Succulents and Cacti

Gritty is one of a kind, a definite conversation starter.

Gritty is a blend of the following:
- Compost made from Philadelphia’s food scraps
- Crushed glass from bottles collected throughout the city
- Biochar

Gritty is composed entirely of byproducts of a recycling process! 

It is available in 2 quart bags (these make great gifts!) as well as 1 gallon bags for larger potting or transplants.
