The possibility of recycling of multilayer packaging waste: Reducing Environmental impacts
(Corresponding) Mumladze T., ŠLEINIŪTĖ A., Denafas G.
Topic:
Solid waste management
Multilayer Packaging Waste (MPW) represents the largest fraction of packaging waste and is mainly composed of multiple plastic films laminated with Al foil. Most produced multilayer film is based on the different polymers, such as: polyester (PET), polypropylene (PP), and polyethylene (PE) as main...Read more
The cultivation of Penicillium strain, isolated from rotten vegetables, on potatoe dextrose broth (PDB) medium enriched in arginine and mineral elements, allowed to obtain a yield of 31.7 mg/g of dry biomass and 9 mg/g of dry biomass into chitin and natural chitosan, respectively. The infrared...Read more

Topic:
Agroforestry, forest and agricultural sustainability
Abstract Agroforestry (AF) is a climate-smart agriculture (CSA) practice of deliberately integrating woody vegetation (trees or shrubs) with crop and/or animal systems to benefit from the resulting ecological and economic interactions. It is recognized as a proactive “negative emissions...Read more
Understory evolution related to organic fertilization in a silvopastoral system established under Pinus radiata D. Don. in an acidic soil
(Corresponding) MOSQUERA-LOSADA M., RODRÍGUEZ-RIGUEIRO F., SANTIAGO-FREIJANES J., RIGUEIRO-RODRÍGUEZ A., FERREIRO-DOMÍNGUEZ N.
Topic:
Agroforestry, forest and agricultural sustainability
Mixed pasture establishment is considered a key point to increase livestock production due to the higher quality it has compared with unmanaged shrubby species. They provide also a set of ecosystem services such as carbon sequestration and higher biodiversity. Moreover, herbaceous pasture...Read more
Pasture biodiversity after five years of establishment of a walnut silvopastoral system fertilized with different types of sewage sludge
ARIAS-MARTÍNEZ D., (Corresponding) MOSQUERA-LOSADA M., RIGUEIRO-RODRÍGUEZ A., FERREIRO-DOMÍNGUEZ N.
Topic:
Agroforestry, forest and agricultural sustainability
Silvopasture is the combination of woody vegetation with forage and animal production on the same land that allows the diversification of agricultural income and productivity. In the silvopastoral systems, the fertilisation with sewage sludge could increase tree growth and pasture production at the...Read more

From Refuse to Resource: E-Plastic as Building Material
(Corresponding) Medina R., Latina H.
Topic:
Electric and electronic waste
The pursuit of the sustainable development goal of responsible consumption and production requires innovative multi-disciplinary approaches. These goals are achieved in the present work with the use of granulated plastic made from waste electronic and electrical equipment (WEEE) panels as a...Read more
Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...Read more

Flame Retardants (polybrominated diphenyl ethers, PBDEs) and Organophoshates, OPFRs) In Dust from Canadian Fire Stations
Brown R., Tarrant D., Gill R., Dhaliwal J., Sarala R., Patton S., Park J., (Corresponding) Petreas M.
Topic:
Urban environment and health
Dust is a good medium to assess indoor exposures to many persistent organics, including flame retardants. With concerns regarding persistence, bioaccumulation and toxicity of many flame retardants, a series of bans and regulations have created shifts in their usage. For firefighters, exposures to...Read more

The comparison of sediment quality in the rivers the Eastern Slovakia by Potential ecological risk index
(Corresponding) Singovszka E., Balintova M.
Topic:
Heavy metals in the environment
The current pollution of sedimentary environment is very serious and exceeds load capacity limit and it is influenced by other external factors such as climate, hydrodynamic conditions, pH, salinity, Eh, temperature and other. This influences can cause the heavy metals are re-released from the...Read more

Determining a Probability of the uncontrolled landfills emergence in Georgia's Rural Areas Using Integrated Methodology
Buachidze N., Dvalishvili N.
Topic:
Solid waste management
In this work, with the support of the local municipality, we’ve collected for each highland region the data showing: the number of population, existence of the main sources causing waste, the quantity of the dumpster, the frequency of the waste removal with the relevant technic etc. Based on all...Read more
