Biosolids Stories

 
 

The wastewater industry has designed a type of circular economy. It is one in which all humans participate and it serves to protect the natural environment. Water resource recovery facilities around recycling our organic wastes, including sewage, food waste, and yard trimmings to produce energy and to produce fertilizer products that can be used on agricultural fields. These initiatives makes use of several beneficial qualities of organic materials we see thrown out as "waste", daily. Not only do we rescue nutrients and divert from landfills and onto agricultural land, green spaces in communities, and reclamation sites, but we provide a financial incentive by saving communities money on inorganic fertilizers.

You can begin to understand the cycle when you think of a growing city producing more food for people, flushing more toilets, and developing more green spaces where people can live and enjoy. The waste from those sources is treated in a way that it can produce energy that is used in homes and to treat and clean water that is returned to the environment. When the material is treated it is then safe to be applied to green space and agricultural land, thus returning the nutrients previously “thrown away” back into the nutrient cycle. As the city grows and more is sent to the reclamation facilities, more energy is generated and nutrients are recycled back into growing systems creating a loop.

We see Denali Water Solutions function as a driver in the circular economy of nutrient recycling by contributing to the environment and economic benefits of communities.

Meeting Various Application Needs

The nutrient composition of biosolids makes it an effective fertilizer in small and large scale agricultural settings. Lystek is managing a diverse collection of research projects and demonstrations to show how effective biosolids can be in your garden or in agricultural fields. Biosolids are showing up in community gardens around the world. Washington DC has partnered with several community gardens to use the utility’s Bloom product. Lystek has even created a company garden for their employees that makes use of their product. The same goes for horticultural applications where biosolids is used by landscaping companies. Tests have shown that biosolids performs well when used as a fertilizer for growing various plants when compared to other additives and fertilizers. Scaling up to larger agricultural applications we have seen time and time again that biosolids are an affordable alternative to chemical fertilizers and often provide a nutrient release cycle and nutrient balance that better serves farmers needs and helps eliminate nutrient runoff that is harmful to waterways.
