Optimum technical operating conditions and treatments for the production of high-purity struvite fertilizer from livestock wastewater.
Kallikazarou N., Koutsokeras L., Constantinide E., Constantinides G., (Corresponding) Antoniou M.
Topic:
Biowaste
Inadequate treatment of nutrient-rich waste streams originating from human activities such as agriculture, animal breeding, urbanization, and industrialization causes an array of environmental problems. Among them are eutrophication of surface water, nutrients and pathogens leaching into...Read more
Modelling the hydrothermal carbonization of cheese whey wastewater in Lesvos island: an application of the 3-step evolution model
Chatzimaliakas P., (Corresponding) Vakalis S.
Topic:
Biowaste
Lesvos island has an extensive dairy production sector, and -at present- eighteen dairy processing facilities are operating. Efficient management of the liquid biowaste effluents has been an issue of interest since the scope is the minimization of the environmental impact. The operating dairy...Read more

Towards decentralizing the energy system: production of bioenergy and bioproducts via anaerobic digestion
(Corresponding) VLACHOKOSTAS C., MICHAILIDOU A., (Corresponding) ACHILLAS C., (Corresponding) MOUSSIOPOULOS N.
Topic:
Biowaste
The model of circular economy has gained worldwide interest. Within its concept, biodegradable waste is viewed as a beneficial resource that needs to be re-introduced in the supply chains. The use of raw materials, energy, and water is also to be minimized. Undeniably, a strong link exists between...Read more

Optimized use of biogenic waste streams through the combined production of bio-based products and bio-hydrogen
(Corresponding) Küppers M., Brunstermann R., Widmann R.
Topic:
Biowaste
Since 2015, there has been a legal obligation in Germany for the districts and cities to collect biowastes separately, which are then treated in a composting plant or fermentation plant. However, in both aerobic and anaerobic biowaste treatment, a large part of the carbon contained in the waste is...Read more
Enzymatic hydrolysis followed by alcoholic fermentation of prickly pears (Opuntia ficus-indica L.) cladodes and fruits using Saccharomyces cerevisiae E1A
(Corresponding) Karalis J., Arapoglou D., Markou G., Eliopoulos C., Papanikolaou S.
Topic:
Biowaste
The cultivation and production of biomass of prickly pear is of particular interest due to the fact that it can be grown in arid areas, producing higher amounts of biomass with lower inputs (water, fertilizers etc.) compared to other crops. The present study examines whether enzyme...Read more
Quality evaluation of composts in the Greek market
(Corresponding) GYPARAKIS S., MARAGKAKI A., MANIOS T.
Topic:
Biowaste
In recent years, many composting products of various organic residues have been placed on the Greek market. Some of the benefits of composting, in addition to protecting the environment, are saving money, reducing wastes, improving soil quality and further complying with EU environmental rules...Read more
