Publication: From piggery wastewater to wheat using microalgae towards zero waste

We are excited to share a groundbreaking new publication from the Performalgae project that delves into the potential of microalgae biomass for agriculture purposes. As the demand for sustainable agricultural practices grows, so does the need to reduce production costs and enhance environmental sustainability.

Microalgae have long been recognized for their efficiency in wastewater treatment, allowing for nutrient and water recycling for agricultural purposes. Additionally, microalgae produce biomass rich in growth-promoting compounds that bolster plant productivity and enhance resistance to adverse conditions. By harnessing the power of wastewater for microalgae cultivation, we can significantly lower production costs, as wastewater serves as a valuable source of nutrients and water.

The publication explores the production of the microalga Tetradesmus obliquus in pre-treated photo-Fenton piggery wastewater, employing various low-cost harvesting techniques such as electrocoagulation, flocculation, and centrifugation in different combinations. Two resulting fractions (biomass and supernatant) were then evaluated for their impact on the germination and growth of wheat plants. One remarkable aspect of this study is its zero-waste approach. All fractions obtained from the process can be fully utilized, minimizing environmental impact and maximizing resource efficiency.

This publication takes us one step closer to achieving sustainable and cost-effective agricultural practices. By exploring the potential of wastewater-grown microalgae biomass, we pave the way for a greener, more environmentally friendly future. The Performalgae project continues to push the boundaries of innovation, offering promising solutions to enhance agricultural productivity while safeguarding our precious ecosystems.
