So, a few months back, someone posted about using #biochar as an ingredient in seed starter. It seems biochar has a lot of potential good uses -- including #PFAS remediation!

"This project aims to investigate whether biochar can be used as a soil amendment to immobilize PFAS in the soil and reduce its bioaccumulation in the edible parts of vegetable crops, such as lettuce and tomatoes. The study will address several key questions: the optimal application rate of biochar in the soil, the frequency with which additional biochar should be applied after the initial amendment, and low-cost modification techniques to enhance biochar's ability to adsorb short-chain PFAS from the soil. This research will involve both laboratory and field studies. The findings will contribute to developing practical guidelines for farmers on the use of biochar in PFAS-affected soils."

"Talking about sewage is not as glamorous as renewable energy, but preventing resource wastage by creating a circular economy is also key to the green transition.”
