Usually, black pigment is made of carbon black which is made by burning fossil fuels and collecting soot that forms in the kiln. It generates around 3 tons of CO2 for each one ton of material made. Organic materials break down as methane when disposed in landfills and methane is a greenhouse gas that's 80 times more powerful than CO2. Recycled Food Waste black is made with a deep carbon negative pigment made from organic waste such as bio-solids and food waste which diverted from landfills.
