Compost Quality Assessment of Various Agricultural Wastes and Organic Manures
(Corresponding) Radwan S., (Corresponding) Ashour E.
Topic:
Solid waste management
Today the quality of compost is the most essential criterion in recycling organic wastes, as well as its marketing and utilization in agriculture. Environmentally safe recycling of organic waste to agricultural land could be crucial to sustaining soil productivity in Mediterranean areas, where soil...Read more
Characterisation of Rare Earth Elements in Waste Printed Circuit Boards (WPCBs) and their bioleaching potential
(Corresponding) Gonzalez Baez A., Purchase D., Garelick H., Pantoja Munoz L.
Topic:
Solid waste management
Printed circuit boards (PCBs) are part of everyday items such as cellular phones and computers, and they constitute a significant proportion of e-waste. PCBs contain hazardous components but also valuable and critical materials such as copper, gold, silver and rare earth elements. Rare earth...Read more
A detailed characterization of household Municipal Solid Waste
Mathioudakis D., (Corresponding) Papadopoulou K., Lytras G., Pavlopoulos C., Dimopoulos N., Niakas S., Melanitou H., Lekkas D., Lyberatos G.
Topic:
Solid waste management
Reliable data on Municipal Solid Waste composition are paramount for the development of environmentally sound, sustainable and economically viable integrated waste management systems. However, no standardized universally accepted waste characterization protocol has been developed, as there are...Read more
Valorisation of waste polyethylene by blending with ethylene-vinyl acetate and incorporation of a new type of compatibilizer
(Corresponding) Simon-Stőger L., Varga C.
Topic:
Solid waste management
Nowadays polyethylene is one of the polymers produced in the greatest volume, therefore, parallelly the amount of generated waste polyethylene (w-HDPE) significant as well. Valorisation and recycling of w-HDPE can be realized by blending with different types of polymers and/or elastomers in order...Read more
Hydrothermal pretreatment optimization for enhanced anaerobic digestion of willow sawdust
ALEXANDROPOULOU M., PAPADOPOULOU K., (Corresponding) ANTONOPOULOU G., LYBERATOS G.
Topic:
Solid waste management
Lignocellulosic biomass including agricultural and forestry residues such as willow sawdust could be used as feedstock for anaerobic digestion (AD). Hydrolysis has been shown to be the rate-limiting step in the case of AD of such substrates. Although being abundant, since the annual world...Read more
A simple and flexible flowsheet process for recycling efficiently and selectively metals from spent fluid cracking catalysts
(Corresponding) Soares H., (Corresponding) Sadeghi M., (Corresponding) Jesus J., (Corresponding) Pinto E., (Corresponding) Almeida A.
Topic:
Solid waste management
Fluid cracking catalysts (FCCs) are used in the oil industry to crack large molecules into smaller hydrocarbons of interest, such as gasoline and other products. Considering the large volume of FCCs waste generated on a yearly basis (about 20 thousand tons of spent FCCs worldwide) as well as its...Read more
Keywords:
Fluid cracking catalysts, simple and nearly-closed process, recovery of La, recovery of Al
Hyperspectral imaging based cascade detection applied to paper, cardboard, plastics and multilayer packaging sorting
(Corresponding) Bonifazi G., Gasbarrone R., Serranti S.
Topic:
Solid waste management
Recycling of post-consumer packaging wastes involves a complex chain of activities, usually based on three main stages, that is: i) collection from households or recovery from MSW, ii) sorting and, finally, iii) mechanical recycling. This paper investigate the sorting logics, hyperspectral imaging...Read more
Remarkable role of experimental olefin-maleic-anhydride copolymer based compatibilizing additives in PET bottle recycling
(Corresponding) Nagy B., Varga C.
Topic:
Solid waste management
Over the past 50 years demand for plastics drastically increased worldwide resulting in plastic wastes causing serious environmental problems. The main market sector of european plastics industry is the packaging industry most of which is polyolefins and poly(ethythylene-terephtalate). Polymer...Read more
Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling
(Corresponding) Retka J., Uhrynowski W., Zhendong Y., Karczewska-Golec J., Bajda T., Drewniak L., Debiec-Andrzejewska K.
Topic:
Solid waste management
One of the most commonly used methods of recycling of spent zinc-carbon batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately it also generates leachates that remain after the...Read more
Keywords:
Zn-C batteries, recycling, leachate, sulfate reducing bacteria, metal sulfide
Screening strains of genus Pleurotus for biomass production in solid state fermentation of agricultural residues
(Corresponding) Diamantopoulou P., Melanouri E., Papanikolaou S.
Topic:
Solid waste management
The ability of several strains belonging to Pleurotus ostreatus and P. eryngii mushroom genera to grow on various agricultural residues was examined and their mycelium growth rates and biomass production (estimated as glucosamine content) were compared. Four P. ostreatus (AMRL 137, 144, 147, 150)...Read more
