Biowastes comprise unwanted material of biological origin, such as biosolids (sewage sludge), animal effluent, wood waste, and green waste. Biowastes can contain high concentrations of organic matter and plant nutrients, making them valuable soil conditioners. However, biowastes can also contain pathogens and contaminants that present a risk to humans and ecosystems. Inappropriate disposal of biowastes is expensive and environmentally damaging. When correctly applied to degraded lands, biowastes can create both economic and environmental value.

We seek to create environmental and economic benefits from biowastes
