Sustainable production of Omega-3-rich fish oil from Tuna by-products using green extraction process

Pedullà A., Ferreri M., Pangallo D., (Corresponding) Calabrò P.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Omega-3 fatty acids are essential for human health, yet the increasing global demand necessitates the exploration of sustainable alternative sources, such as fishery by-products. An innovative and environmentally friendly extraction method, previously applied to small fish by-products, was employed...Read more

Sustainable crop management through the use of biochar and manure based biofertilizers

Ferreiro-Domínguez N., Álvarez-López V., Lado-Liñares M., Santiago-Freijanes J., (Corresponding) Mosquera-Losada M.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

The application of biochar to soil can contribute to reducing climate change through the development of the bioeconomy. However, biochar does not provide adequate amounts of nitrogen to the soil. Therefore, it is necessary to develop biofertilizers based on a mixture of biochar with a residual...Read more

Firm Size and Sustainability Certifications: Understanding Business Economic Drivers in Certification Adoption

(Corresponding) Liscio M., Bregoli D., Narang G., Perugini F., Sospiro P.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This study explores how firm size influences sustainability certification adoption in Italy. Expanding from a regional to a national scope, a two-step methodology is used: web-scraping to assess how firms present certifications online and statistical analysis correlating adoption rates with firm...Read more

Towards a Sustainable Future: Circular Strategies for Critical Raw Materials Recovery from End-of-Life Magnets

(Corresponding) Sanna A., Armas C., Serci M., Artizzu F., Marchiò L., (Corresponding) Serpe A.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

The transition to a circular economy is crucial for addressing the environmental and resource challenges posed by traditional linear production models such as resource depletion, environmental degradation, and waste accumulation. In this context, growing interest is devoted to critical raw...Read more

A Magnetic Approach to Sustainable Chlorella vulgaris Harvesting: Methods and Applications

(Corresponding) Maia C., Loureiro J., Soares O., Pereira M., Pires J.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Microalgae are unicellular microorganisms with many applications; however, their high harvesting costs compromise their large-scale use. Magnetic separation has been explored as a potential solution for overcoming harvesting challenges. In addition to promoting microalgal harvesting, the magnetic...Read more

Use of waste dealuminated metakaolin in alkali-activated cement mixes

Elsebaei M., (Corresponding) Mavroulidou M., Micheal A., Centeno M., Shamass R., Rispoli O.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This paper explores the feasibility of using dealuminated metakaolin (DMK), a hazardous by-product of the alum industry, in alkali-activated cement (AAC) mixes, as an outlet for this voluminous hazardous waste, alternative to landfilling. After reviewing global DMK waste manage-ment practices and...Read more

Feasibility of peat soil stabilisation with solid waste material inclusions and biocementation treatments

(Corresponding) Mavroulidou M., Gunn M., Joshi S., Sanam I., Murad M., Garelick J.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This paper studies the stabilisation of a peat railway embankment foundation soil from East Anglia, UK, using solid waste material inclusions and biocementation treatments. Peats are weak, high water content soils which lead to construction problems, due to the high water content and poor...Read more
