Compostable Sponges

Summary

Challenges

Composty wanted to go beyond material choices to validate the entire environmental footprint of its compostable sponges. Their goals included:

Measuring emissions across the full product lifecycle; from sourcing to disposal

Benchmarking against traditional plastic sponges

Identifying high-impact areas for further improvements

Backing sustainability claims with transparent, science-based data

Solutions

To meet these goals, Composty partnered with CarbonBright to run a comprehensive, cradle-to-grave Life Cycle Assessment (LCA) on their compostable sponge line. Through our AI-powered platform, Composty was able to:

Automate impact measurement, cutting time, cost, and manual effort

Assess multiple categories including carbon, transportation, and disposal

Model real-world scenarios like composting vs. landfilling

Generate audit-ready, ISO-aligned reports to support sustainability claims

Results

CarbonBright helped Composty turn environmental data into tangible value:

Validated 70x lower end-of-life emissions when composted vs. landfilled

90% less packaging volume during shipping, drastically cutting transport- and packaging-related emissions

Identified “use phase” as the highest contributor to emissions, prompting customer education to maximize impact

Enabled credible, science-based sustainability storytelling that supports Composty's product positioning

About Composty

Composty is a UK-based, family-run eco-cleaning brand founded by Helen and Matt, inspired by the birth of their daughter. With a mission to make affordable, zero-waste cleaning alternatives accessible, Composty offers compostable sponges and packaging that eliminate plastic, reduce landfill waste, and promote a circular, soil-positive lifecycle.

Their commitment to science-based sustainability and customer transparency has made them a rising leader in the eco-cleaning space.

Industry Overview

Plastic cleaning products are a silent but significant environmental threat. Globally, plastics generate 1.8 billion tonnes of GHG emissions, and the UK discards 400+ million plastic sponges annually—each taking 500+ years to decompose.
Yet, credible data on eco-friendly alternatives is hard to come by.
Composty set out to change that with compostable, plastic-free sponges—designed to reduce landfill waste and carbon impact.
To validate this shift, they needed a science-backed way to measure and communicate their full product footprint.

CarbonBright Solution

Composty’s compostable sponge was designed to eliminate plastic waste and reduce environmental harm. But to validate its impact, the product needed credible, science-backed data.
Using CarbonBright’s AI-powered LCA platform, Composty conducted a full cradle-to-grave environmental analysis. This enabled Composty to:

Measure emissions across the sponge’s entire lifecycle from raw material sourcing to end-of-life

Compare & benchmark performance against traditional plastic sponges across packaging, transport, and disposal

Model real-world scenarios like composting vs. landfilling to surface true end-of-life impact

Generate audit-ready, ISO-aligned reports that support marketing claims and retailer communications

With CarbonBright, Composty’s sponge now stands on a foundation of verified impact; helping the brand communicate with proof and continue improving product performance.
