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 is ALG-AD doing?

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

The valorisation of produced algal biomass will be achieved through the animal feed preparation. The process of hydrolysation of algal biomass with the assessment of pathogens and heavy metals level, permitting to use this biomass for the animal (piglet and fish) nutrition trials.

A clearer regulatory picture emerges

Posted on

A common barrier in the transition between development and rollout of a new technology lies in regulation. Innovation means pushing the boundaries, and policy often lags behind, causing problems and delays for those cutting-edge organisations trialling new approaches. The ALG-AD project is working with NNFCC, a leading bio economy consultancy, to clarify where current regulatory barriers exist in relation to our work, where we are using the digestate from AD to cultivate microalgae. Our review will identify where there are grey areas which need addressing to enable larger scale adoption. The initial regulatory review is in progress, and has highlighted that there are indeed challenges in this area – but the team are also working to provide guidance for stakeholders to navigate this difficult area.

The draft legislation from WG would designate the whole of Wales as an NVZ

Posted on

Whilst environmental benefits of designating all of Wales as an NVZ would be undoubtable, this needs to be finely balanced with commercial needs of the farming community. Our work on ALG-AD is looking to help agricultural communities to achieve this balance, by finding alternative solutions for digestate, which can also generate income for AD. https://www.fuw.org.uk/en/news/13882-draconian-wg-water-quality-proposals-would-push-dairy-farms-over-the-edge-fuw-dairy-committee-warns Read More

Zoom is the new norm

Posted on

Two weeks into the new world of working from home and the Zoom conference call is now the new normal for the ALG-AD team. In fairness, the team had already been using the platform widely as we’re split across several countries. But in the era of the lockdown, our strong communications foundations have really proven themselves. Read More
