Is human waste OK to use for compost or fertilizer? | Brian's Science and Technology |
Any farmer will tell you that when it comes to efficiently growing food, compost is “black gold”. But some fear that fertilizer or compost made from human waste could be at risk of containing heavy metals, pathogens, or pharmaceuticals causing many environmentalists to consider it unsafe for enhancing plant growth. Others however, counter that contaminants are already part of our environment – they’re in the soil, water, and food we currently consume – and compost made from human wastes is no more unsafe than the soil that our food is already grown in. Fact is, no scientific evidence currently exists proving either stance is right or wrong.
