Articles on Wastewater sludge

We sampled sewage sludge from 13 wastewater treatment plants across three states. We found every resident adds microplastics to farmland, in dried sewage sludge (biosolids) used as fertiliser.
We need to pay close attention to the potential impacts that high levels of microplastics might have on environments and find ways to reduce microplastic levels in Canada’s wastewater stream.
Energy companies are marketing a new fuel: ‘renewable’ natural gas. But it’s not the same from a climate change perspective as wind or solar energy.
We must stop using biosolids for farmlands immediately, especially when alternative ways to recycle wastewater sludge already exist.
