Greener alternatives from microalgae-treated food wastewater
An innovative process using an alkaliphilic microalgae and bacteria consortium to transform food processing wastewater into valuable biomaterials, reducing dependence on petroleum-derived products and promoting sustainability.
Overview
This solution utilizes an alkaliphilic microalgae and bacteria consortium (AMBC) to transform food processing wastewater into valuable biomaterials. The process specifically targets the depolymerization of polysaccharides and proteins present in the wastewater to produce sustainable building blocks. These biomaterials have potential applications in biomedical and agro-industrial sectors, offering greener alternatives to petroleum-derived products.
Technical specifications
Key features:
- Utilizes waste from maize lime-cooking and whey as nutrient sources.
- Operates in a 100 L raceway pond fermentation process.
- Produces polysaccharides, proteins, and calcium derivatives.
- Avoids the use of fresh water by repurposing wastewater.
- Can be implemented in situ with potential for small-scale biofactories.
Applications:
- Biomedical materials
- Agro-industrial products
- Circular economy strategies
Technology readiness level
This technology is at TRL 5, having been demonstrated in relevant environments with plans for further validation and economic evaluation over the next 1.5 years. The next steps include designing photobioreactors and conducting life cycle analyses to ensure environmental benefits.
