Valorization of poultry manure extract enriched with sodium acetate in mixotrophic cultivation of Auxenochlorella protothecoides
Langousi I., Markou G., (Corresponding) Arapoglou D.
Topic:
Recycling of materials to new products
Poultry manure (PM) is byproduct of intensive agricultural production and can be used as a low-cost microalgae growth substrate due to its nutrient and protein-rich content. Microalgae are capable to grow rapidly and thrive in different substrates, thus serving as a valuable source of biomass. In...Read more

Degradation assessment of high-density polyethylene (HDPE) debris after long exposure to marine conditions
(Corresponding) Lourmpas N., Efthimiadou E., Filippides A., Papanikos P., Lekkas D., Alexopoulos N.
Topic:
Recycling of materials to new products
In the present investigation, the degradation of high-density polyethylene (HDPE) in marine environments, under ultraviolet (UV) radiation and saltwater conditions, was examined. HDPE debris were collected from the coastal areas nearby Korinthos, encompassing a wide range of exposure durations,...Read more
Valorization of waste graphite deriving from "End Of Life Lithium-Ion Battery recycling" for a second use in wastewater treatment.
(Corresponding) Premathilake D., (Corresponding) Vaccari M., Botelho Junior A., Tenório J., Espinosa D., Colombi F.
Topic:
Recycling of materials to new products
Exponential utilization of Lithium-ion batteries (LIBs) has produced a notable amount of hazardous waste recently. The current practices focus on recovering precious metals available in cathode giving less priority for anode material (graphite) recoveries and valorizations. However, thinning of...Read more

Chemical properties of plant-based biochar to be used as soil fertiliser in Galicia (NW Spain)
Ferreiro-Domínguez N., Salman S., (Corresponding) Mosquera-Losada M.
Topic:
Recycling of materials to new products
The excessive use of chemical fertilisers can cause soil acidification, depletion of soil quality, and biodiversity loss. Alternatively, biochar can improve crop productivity due to its ability to bind macronutrients and micronutrients and also adsorb various contaminants. However, the properties...Read more

Coffee ground biosorbent for nitrite and nitrate recovery and soil nutrient
Ying T., (Corresponding) Sethupathi S., Hon L.
Topic:
Recycling of materials to new products
Nitrate (NO3-) and nitrite (NO2-) are two forms of nitrogen that contribute to the occurrence of eutrophication if found in excess concentrations. Conversely, nitrogen is one of the major macronutrients required for healthy plant growth. The purpose of this work is to evaluate the recovery of NO3-...Read more
Towards sustainable plastics recycling: assessing the integrity status of polypropylene (PP) debris to recycle marine-degraded materials
(Corresponding) Lourmpas N., Kyriakakis E., Efthimiadou E., Papanikos P., Lekkas D., Alexopoulos N.
Topic:
Recycling of materials to new products
Polypropylene (PP) is a widely used polymer with significant environmental implications when improperly disposed. Effective recycling strategies for PP are crucial for mitigating plastic pollution and achieving sustainability goals. This investigation focuses on classifying PP debris based on their...Read more
EPS waste management from coastal cleaning actions: identification of contamination sources, collection, treatment, and re-use in cement-based materials
(Corresponding) Alexopoulos N., Filippidis A., Lekkas D., Metaxa Z., Prokopiou V.
Topic:
Recycling of materials to new products
Finding sustainable solutions to reduce plastic waste in response to today's global environmental challenges is a high priority for the scientific community. Collaboration among many scientists with diverse research interests is the key to success for integrated proposals for the collection,...Read more
