ALG-AD - Creating value from waste nutrients by integrating algal and anaerobic digestion technology


Project Summary

What is ALG-AD?

ALG-AD is a Interreg NWE funded project in which new technology is being developed to take excess waste nutrients produced from anaerobic digestion of food and farm waste to cultivate algal biomass for animal feed and other products of value.

ALG-AD brings together a group of scientists and engineers from 11 different partners in four countries across North West Europe. These academics are working together with industry to develop a circular economy solution to create wealth from waste.

 

Why is the project necessary?

There is an urgent need to develop sustainable food and farming.  

North West Europe is a densely populated and intensely agricultural area. It thus contributes disproportionately to food and farm waste produced in the EU each year.

Increasing amounts of food and farm waste are processed using anaerobic digestion (AD). AD converts waste to biogas used for energy and a liquid nutrient rich digestate, most of which is returned to land as a biofertiliser.

However, there are strict limits on the amount of digestate which is allowed to be put back on agricultural  land. Strict limits are imposed with EU legislation and so-called Nitrate Vulnerable Zones. This is increasingly creating excess unwanted nutrients. 

The ability to use these excess nutrients to produce new products presents a circular economy solution. 

 

How can ALG-AD help?

ALG-AD combines algal and AD technology.  Microalgae, mainly photosynthetic microorganisms will be cultivated, converting the unwanted nutrients into biomass. The cultivated algal biomass is rich in protein and other useful compounds, and can be used to generate sustainable animal feed products and other useful bio-products.

 

What will ALG-AD be doing?

ALG-AD is building three pilot facilities at 3 distinct ‘real life conditions locations in North West Europe: Devon, Ghent and Brittany.  Each facility will use local conditions to grow the algae and record results. Information from the three pilots will be used to generate Decision Support Tools. These tools together with demonstration to stakeholders will promote adoption of the new technology.

Using algae to promote agricultural sustainability and the circular economy

Posted on

Algae are being used to develop new technology to clean up waste. Scientists at Swansea University are leading on a €5.5 Million eco-innovative project. The ALG-AD project could potentially result in a circular economy solution whereby excess waste nutrients produced from anaerobic digestion of food and farm waste are used to cultivate algal biomass for animal feed and other products of value.

UK Food Standards Agency pays a visit to ALG-AD

, Swansea University

Members of the Food Standards Agency have paid a visit to Swansea University, allowing staff members on the ALG-AD project to showcase their work. The ALG-AD project is aiming to create a circular economy using waste nutrients produced from the anaerobic digestion process to grow algae. The algal biomass produced will then be transformed into animal feed and other value products. The FSA staff were treated to a tour of the aquaculture facilities, followed by presentations on ALG-AD and a select few projects currently ongoing at the University.

Swansea scientist heads to #AlgalBBB in Seattle

, Seattle, Washington, USA

Dr Claudio Fuentes Grunewald, one of our project scientists based in Swansea University, recently had the chance to talk about the work being undertaken by the project at the 8th annual International Conference on Algal Biomass, Biofuels and Bioproducts, held in Seattle. His work demonstrates the membrane technology can concentrate and purify phycoerythrin produced by P. purpureum on a large scale.
