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

One-step Synthesis of TiO2/ZnO Nanocomposites by Refluxing Methods for Photochemical Degradation of Humic Acid

(Corresponding) Fadillah G., HIdayat R., (Corresponding) Wahyuningsih S.
Topic: 
Nanomaterials in the environmnents applications and effects
Synthesis of TiO2/ZnO nanocomposites (TZN) through one-step refluxing method for photochemical degradation of humic acid (HA) in aqueous solution has been studied. Titanium isopropoxide (TTIP) and ZnSO4.7H2O were used as a starting material under base solution at 120 oC for 24 hours. TZN materials...Read more

The role of Life Cycle Assessment to measure progress on the Circular Economy

(Corresponding) Corona B., Shen L.
Topic: 
Life cycle analysis (lca)
The circular economy (CE), as opposed to the current linear economy, is seen as a sustainable economic system where the economic growth is decoupled from the resources use, through the reduction and recirculation of natural resources. In the shift towards the CE, quantifying the circularity of...Read more

Thermal degradation of perfluorooctanoic acid (PFOA)

(Corresponding) Stockenhuber S., Weber N., Dixon L., Lucas J., Grimison C., Bennett M., Stockenhuber M., Mackie J., Kennedy E.
Topic: 
Soil and groundwater contamination and remediation
Per - and polyfluoroalkyl substances (PFAS) are a group of environmental contaminants, that are dispersed throughout the world. A number of areas have been affected by their persistence and biomagnification. PFAS remediation of contaminated material requires extensive knowledge of the species...Read more

Early-stage LCA of a novel fuel flexible CHP technology based on biomass gasification and a SOFC

Moretti C., Rühlin V., (Corresponding) Corona B.
Topic: 
Life cycle analysis (lca)
To mitigate climate change and reduce the consumption of fossil fuels, more efficient energy production is necessary. Combined heat and power systems (CHPs) are a key technology to reach such an objective, due to its higher energy efficiency than the separate production of heat and electricity...Read more

Effect of chain length on the pyrolysis of perfluorocarboxylic acids

(Corresponding) Dixon L., Stockenhuber S., Weber N., Lucas J., Grimison C., Stockenhuber M., Mackie J., (Corresponding) Kennedy E.
Topic: 
Emerging pollutants
Per- and polyfluoroalkyl substance (PFAS) are increasingly becoming the contamination issue of our time, due to their environmental persistence, bioaccumulation and mounting evidence of their toxicity. Herein we examined the pyrolytic decomposition of a series of perfluorocarboxylic acids via the...Read more

Thermal Decomposition of Chlorpyrifos - an Experimental Investigation

(Corresponding) Weber N., Stockenhuber S., Dixon L., Lucas J., Grimison C., Stockenhuber M., Mackie J., Kennedy E., Benhelal E.
Topic: 
Soil and groundwater contamination and remediation
Organophosphate compounds are a group of chemicals that are commonly used in pest control. One widely used organophosphate is chlorpyrifos (CPF), which has been associated with acetylcholinesterase inhibition (AChE), an acute neurotoxin. Further, under thermal decomposition conditions, such as...Read more

Polyethersulfone/Polyamide11Cost Effective, Antifouling- Nanofiltration Blend Membrane

(Corresponding) Shalaby M., Abdallah H., Alanezi A., shaban A.
Topic: 
Water treatment
Nanofiltration membranes (NF) are considered and used extensively in seawater softening, food, textile, and mining industries for the removal of di-and multi-valents to increase RO lifetime by decreasing fouling rates, and chemical cleaning intervals. In this work, blend membranes of...Read more

The effect of the presence of zinc on the precipitation of CaCO3 from supersaturated solutions

(Corresponding) Koutsoukos P., NATSI P., MOUSTAKI E.
Topic: 
Heavy metals in the environment
Precipitation and dissolution processes of calcium carbonate in natural aquatic systems, are responsible not only for the regulation of pH but also for the transport of pollutants to and from sediments. Of interest in these processes, is the role of the presence of heavy metals in the aquatic...Read more
