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

The Circular Economy Research and Innovation Group (CERIG) Wales met last week to share project and policy updates, as well as to consider the EU Circular Economy Action Plan. Representatives from Welsh Government updated the group on national regulation developments, and current CE consultation processes, seeking feedback on proposals to:- • move towards zero waste by 2050 • scrutinise how we use resources • encourage the reuse, repair and remanufacture products and materials • maximise the economic and social opportunities of a more circular economy. Participants also considered implications for UK businesses of the EU’s Circular Economy Action Plan, for example, the mandatory requirements to increase the sustainability of goods and services, and how this might be approached.

While large-scale operations across the partnership have resumed full steam, laboratory work has also restarted at Swansea University where new results are expected to provide new insights for the implementation of the ALG AD technology. The experimental work is looking into exploring microalgal growth performances and biochemical composition, when cultivated on a range of digestates provided by the ALG-AD partners and originating from different waste sources: kitchen and food waste, pig manure, and plant waste. The three digestates are being used to grow the microalgae Chlorella vulgaris and Scenedesmus obliquus at Swansea University and the experiment will also be conducted on a microalgal consortium (Desmodesmus sp. and Chlorella sp.) and on the oil-rich fungus Aurantiochytrium mangrovei in Belgium and in France, respectively.

With the help of Kristof Severijns, from Innovatiesteunpunt (BE), the ALG-AD team from Ghent University was put in contact with 5 farmers that are interested in further using the digestate generated by their activities for microalgal cultivation. Read More
ALG-AD Investment site UGENT-INNOLAB in Belgium: General introduction and operation during the COVID-19 crisisPosted on
The investment site 3 of Interreg NWE ALG-AD project is located within the premises of Innolab CVBA, Oostkamp, Belgium (about 90 km North-West of Brussels). The pilot facility accommodated in a polycarbonate greenhouse comprises a bag (paper) filtration unit for digestate pre-treatment, a 2600-litre vertical reactor (VR), and a 600-litre horizontal bioreactor (HR) operated in batch mode for microalgae cultivation. The liquid fraction of digestate used as a substrate is collected from an anaerobic digestion (AD) plant in Pittem (20 km South of Oostkamp) that processes food and farm waste of plant-origin.

The ALG-AD team today welcomed over 50 attendees to a virtual open day at our pilot algal cultivation facility at Langage AD. The whole UK ALG-AD team took part in the event, which included presentations and interactive breakout sessions to give attendees a chance to take part in discussions. Dr. Alla Silkina, who organised the event, noted “This has been an excellent opportunity to showcase the work we have been doing at Langage. We had some great, challenging questions, and got the chance to understand the perspectives of AD stakeholders through the session” Louise Hall, Project Manager, added “We had hoped to welcome visitors to the Langage site for a face to face open day, however, the current Covid restrictions meant the team had to be creative and find an alternative way to share practical demonstrations with stakeholders. Through videos, photographs, and talks, the team managed to share the story of our work so far, and I am very grateful to everyone for their efforts.” Read More
The Covid-19 pandemic situation in France affected the operation of the algal production pilot. Access to the pilot was restricted from the middle of March and the research team could only work analysing previously obtained data, without access to the laboratory and cultivation facilities. As a result, the data review has shown the importance to add certain elements to the media such as micronutrients and metals. Now, that lockdown restrictions have been lifted in France, the algal cultivation reactor at Cooperl managed by the research team from CNRS is prepared for the new batch of thraustochytrids microalgae Aurantiochytrium mangrovei. The media has been adjusted with new nutrient compounds, and a new inoculation has been completed. The team in France follow a heterotrophic approach to algal cultivation Read More
The ALG-AD team will be holding an open day at Langage AD for interested stakeholders. It will be an opportunity to share our expertise on our solution to valorise excess digestate, by growing algae. Read More
The doors are open again at Langage AD, where the team are optimistic that a quick restart will enable a successful summer algal culture growth season on ALG-AD. Jose Ignacio Gayo Pelaez and Vanessa Ndovela have returned to the greenhouse at AD plant location this week, where changes in COVID-19 restrictions have meant that work can restart at Langage. With the strict observation of social distancing protocols and adjustment to standard operating procedures, the 2 team members responsible for growing the microalgae are back at work. The first task is to clean and sterilize all the equipment, especially Photobioreactor to be ready for inoculation at the start of June. Read More
Biogaz Europe is the reference event for biogas in France. This year ALG-AD attended, spreading the word about the project and our aims and objectives.
An open day and workshop was held recently at the lead partner facilities in South Wales to allow a chance for face to face discussions to take place between partners, and to see the reactor facilities available at the lead partner.
ALG-AD attended this day and a half transnational event as it focussed on the results achieved by the 83 NWE projects funded so far.
Particularly useful was guidance on how to further support uptake and impact of the work being undertaken by researchers.
Professor Carole Llewellyn was invited to talk about the work being done by ALG-AD at the close out conference held in Slovenia for the Saltgae project.
The workshop aim was to look at different aspects of microalgae growth, harvesting, and production methods.
Our colleague Jai Sankar Seelam gave an introductory pitch on the project to colleagues and students at an inspiring afternoon events at the university.
His talk took place in a session which was organised by an end-of-waste business platform. It was billed as a unique opportunity to learn about the strategic developments in policy and industry, and current efforts at the faculty, and of the the efforts being made towards a more sustainable future.
