Using waste nutrients to cultivate microalgae – Swansea team publishes new peer-review paper

Posted on

A Swansea University team has published a new article, detailing a novel approach to reuse food and farm waste at an industrial scale, using microalgae. The paper explains the ways in which algae can be cultivated using excess nutrients, the optimum two-step approach used to maximise productivity, and how this biomass is optimally suited for use as an animal feed ingredient. Implementation of circular approaches in industry, by minimising waste and optimising reuse of resources, is of critical environmental importance. Microalgal cultures are particularly adept at waste remediation, and are also incredibly versatile in how they can be processed and applied. This article explains in more detail how the ALG-AD team have demonstrated the ability of microalgae to remediate organic waste at an industrial scale. Read More

Circular Economy in action: Using digestate to cultivate microalgae for fish and animal feed

Posted on

ALG-AD is exploring ways to develop a circular approach to microalgae cultivation, utilising the by-products from the AD/biogas industry, to generate products of value for another. The team has built three facilities that are already using the nutrients in digestate to cultivate microalgae. So far, the ALG-AD team has focussed on the production of biomass for use as animal feed, however additional funding has been allocated to the team to expand on the work already done to also cultivate algae for use as fish feed.

Circular Economy in Wales – latest developments

Posted on

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.

ALG-AD experiments resuming at Swansea University

Posted on

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.

ALG-AD Investment site UGENT-INNOLAB in Belgium: General introduction and operation during the COVID-19 crisis

Posted 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.

ALG-AD virtual open day welcomes an international audience

Posted on

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
