Sustainable and Cost-effective Approach for Treatment of Plating Industrial Wastewater Effluents

(Corresponding) Boguniewicz-Zablocka J., Naddeo V., (Corresponding) Corpuz M.
Topic: 
Heavy metals in the environment
The wastewater resulting from the plating industry contains high contents of toxic metals, such as chromium, which is a serious threat to the environment due to its cumulative effects and non-degradability. Several methods have been actively investigated to remove heavy metal ions from aqueous...Read more

Assessment of Pesticide Occurrence, Attenuation, and Transport Dynamics in the Pampanga River Basin

(Corresponding) AGUSTIN R., ROLLON A., KWAN C., BALLESTEROS F.
Topic: 
Environmental data analysis and modelling
The goal of this study is to detect chlorpyrifos, a pesticide, in the Pampanga River basin and to create a new model, or improve upon an existing one, that can accurately predict the concentration levels of micro pollutants in the river bed. The complete dry and wet seasons are accounted for by...Read more

Short-time numerical simulation of ultrasonically assisted electrochemical removal of strontium from water

(Corresponding) Licht K., Lončar G., Posavčić H., Halkijević I.
Topic: 
Water treatment
3D numerical simulations and measurements on an electrochemical reactor were used to analyze the efficiency of strontium removal from water, with and without simultaneous ultrasound treatment. Ultrasound was generated using 4 ultrasonic transducers with an operating frequency of 25 kHz. The reactor...Read more

Settling and filtration experiments for the removal of flocs produced by a hybrid sono-electrochemical process

Posavcic H., Halkijevic I., (Corresponding) Vouk D., Nakic D.
Topic: 
Wastewater treatment
Choosing the right method for floc separation after electrochemical treatment seemed to be a problem in a number of previous research papers. Therefore, ultrasonic and electrochemical (sono-EC) processes in circulating flow mode were combined with settling and filtration to treat the oily...Read more

UTILIZATION OF AGRICULTURAL AND URBAN PLASTIC WASTE REVIEW: INTRODUCTION TO PYROLISIS AND HYDROCARBON REFORMATION

KOUMPAKIS D., (Corresponding) VLACHOKOSTAS C.
Topic: 
Waste-to-energy
Agricultural and urban waste consist of large quantities of biomass and petroleum originated waste. These two categories are rich in hydrocarbons which can be utilized again after their first life cycle. Pyrolysis is a thermochemical process in which solid hydrocarbons decompose in conditions of...Read more

The AquaSPICE Industrial Symbiosis Enabling Platform

Earnshaw S., Dedousis P., Vyrkou A., Pieri T., Arampatzis G., (Corresponding) Angelis-Dimakis A.
Topic: 
Circular economy and industrial symbiosis
The role of the AquaSPICE Symbiosis Enabling platform is to facilitate the development of one-to-one waste reuse value chains, through the collaboration of an industrial waste source and a potential waste user. This can be achieved by adopting a three-step process: (i) map and characterize the...Read more

Circular Cities: Challenges and Opportunities towards their transition to a green, smart and circular economy.

Liogkas V.
Topic: 
ESG (Environmental, Social and Governance) and circular economy
Cities cover 3% of the land on Earth, however with more than 70% of the population expected to live in urban areas by 2050 they drive almost three-quarters of GHG emissions. They account for two-thirds of global energy demand, consume 60-80% of natural resources and generate 50% of waste. Urban...Read more

Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale

Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic: 
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...Read more

Mass-transfer processes of toxic hexavalent chromium adsorption onto food waste adsorbent

(Corresponding) ASSELAH A., AFRICANO CANI Z., ABRAÃO MANUEL BUZI N.
Topic: 
Water and wastewater treatment and reuse
Heavy metal pollution caused by industrial operations is a global environmental issue. Chromium, used in chrome plating, textile dyeing, wood preservation, and metal fnishing, is classifed as a highly toxic agent to humans and other living organisms. To minimize health risks, these contaminant...Read more

Fluctuation of Nighttime Ground Level Ozone Due to Artificial Light

Mohamad Nazir A., Ramli N., (Corresponding) Ismail M., Awang N., Nordin N., Abdul Wahab S.
Topic: 
Air pollution
Ultraviolet (UV) radiation creates ground-level ozone (O3) during the day and is subsequently eliminated by nitrogen oxides at night. However, excessive artificial light use, those results in light pollution, may interfere with the chemistry of ground-level O3 at night by supplying enough energy to...Read more
