Putting accelerated carbonation of bottom ash into practice: operation of a semi full scale continuously fed rotating drum reactor

Brück F., Schnabel K., (Corresponding) Weigand H.
Topic: 
Hazardous waste management
Bottom ash is the dominant residue from municipal solid waste or refuse-derived fuel incineration. Disposal costs chiefly depend on the leachability of trace metals and salts. The mobility of these constituents is classically minimized by ageing the material for several months. Ageing involves the...Read more

Detection of Alpha-induced radioluminescence in the ultraviolet C range for Nuclear Decommissioning Applications

(Corresponding) Gamage K., Crompton A.
Topic: 
Hazardous waste management
The close range of traditional alpha radiation detectors makes detection time-consuming and potentially hazardous. Alpha-induced radioluminescence in the ultraviolet C (UVC) wavelength range (180-280 nm) may be the mechanism through which stand-off detection can be achieved. The UVTRON (Hamamatsu...Read more

Analysis of the content of germanium, tellurium and thallium in the grounded waste of electronic equipment

(Corresponding) Fornalczyk A., Willner J., Jablonska-Czapla M., Rachwal M.
Topic: 
Hazardous waste management
The article draws attention to the problem of the presence in waste electrical, electronic equipment (WEEE) of selected metals from the group of critical metals (germanium), strategic metals (tellurium) and highly toxic elements (thallium). Due to low content of these metals in e-waste, they are...Read more

Conversion of coal fly ash by-products into high-grade zeolite by a quasi natural crystallization process

Zgureva D., (Corresponding) Boycheva S.
Topic: 
Hazardous waste management
Recently, the synthesis of zeolites from coal fly ash (FA) has been extensively studied regarding the process optimization, industrial upscaling and technological commercialization. The obtaining of fly ash zeolites (FAZ) is based on the transformation of aluminosilicates of FA by alkaline...Read more

Reducing the environmental impact of construction wastes by their use in the preparation of construction mixtures

(Corresponding) Junak J., Sicakova A.
Topic: 
Hazardous waste management
At present, great emphasis is placed on protecting the environment. Civil engineering, mainly cement production, greatly pollutes the surrounding environment. Even the excavation of aggregate, which is one of the basic components of concrete, does not make any extra contribution to the...Read more

Health Care Waste Management: Challenges and Solutions

(Corresponding) Halldorsdottir S.
Topic: 
Hazardous waste management
Limited attention has been paid to health-care waste management despite an increase in public concern about the management of such waste on a global basis. The objective of this study was to analyse the issues and challenges of health-care waste management as well as possible solutions. It is...Read more

A new sustainable approach in recovering Cobalt from “hard metal” production by-products

Amadou O., DE GAUDENZI G., MARCHESELLI G., PIREDDA M., (Corresponding) SERPE A.
Topic: 
Hazardous waste management
The present work shows the capability of Maleic Acid solutions to tune the amount of Co in cemented carbide-based recovery powders with a Co content exceeding the threshold (10% Co) for industrial manufacturing in Hard Metal production and required by safety regulations. Maleic acid solutions react...Read more

Characterisation of Radioactive Contaminated Waste: Alpha-Induced Air-Fluorescence Detection Under Daylight Conditions

(Corresponding) Gamage K., Crompton A.
Topic: 
Hazardous waste management
Short travel of alpha particles in environments complicated the detection and characterisation of alpha-emitting contamination in mixed radiation fields in nuclear decommissioning sites. As a result, detection of alpha-induced radioluminescence became popular in nuclear decommissioning applications...Read more

ANALYTICAL DEVELOPMENTS FOR PVC RADIOOXIDATION STUDY, IN SIMULATED DISPOSAL CONDITIONS

(Corresponding) Chantreux M., Rossignol S., Ricard D., Bussière P., Therias S., Gardette J., Wong-Wah-Chung P.
Topic: 
Hazardous waste management
Radioactive waste is generated by the use of radioactive materials in industry, research and medicine, as well as in nuclear power plant. The management and disposal of such waste is, therefore, a very important issue. In France, the estimated volume for the low intermediate-level long-lived...Read more

Declassification of drilling waste from oil & gas exploitation through end-of-waste criteria to be used as construction materials

Kazamias G., (Corresponding) Zorpas A.
Topic: 
Hazardous waste management
All activities related to Oil & Gas Exploration, Production, Storage and Transportation involve waste generation associated to potential risk to environment. Waste types are related to Exploration and Producing (E&P) activities. These activities are: Drilling operations, Production...Read more
