Organics cart and container trends

WHEN it comes to figuring out what cities, states and provinces are still throwing away, food residuals from households, commercial businesses and institutions continue to top the list. And as more jurisdictions look to adopt Zero Waste goals and mitigate methane emissions from landfills, the obvious candidate to boost diversion rates is the food residuals stream. In cities and towns that already ...

Containment for Soil, Sediment, and Sludge

Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, ...

Experimentally analysing compressive and tensile strengths of concrete containing steel waste fibres

Considering increasing growth of using other materials in concrete for increasing its quality, studies on fibres have been recently extended. Existence of fibres can compensate for some of the weaknesses of concrete in terms of its brittleness and fragility. Now, in this study, role of steel waste fibres in compressive strength of cubic samples and tensile strength of cylindrical samples at ages ...

Biotreatment of waste gas containing pyridine in a novel rotating rope biofilter

A novel Rotating Rope Biofilter (RRB) has been developed especially for the treatment of Volatile Organic Compounds (VOCs) at higher loadings and characterised by high volatility along with high water solubility. The RRB provides a higher interfacial area (per unit reactor liquid volume) along with high oxygen mass transfer rate, greater microbial culture stability, and consequently higher ...

Indicators to assess the recovery of natural resources contained in demolition waste

Demolition waste materials are one of the major industrial waste deposits in many countries and represent an important quantity of potential resources that are not exploited, because the major part of these wastes go to landfill. Indeed, recycling or recovery of demolition waste can reduce the need of primary natural resources. This article gives indicators and a method to analyse demolition ...

Exergy analysis of the process of wet-process phosphoric acid production with full utilisation of sulphur contained in the waste phosphogypsum

The wet-process phosphoric acid is produced by decomposition of phosphate raw materials with sulphuric acid. This gives a large amount of waste product-phosphogypsum. The thermochemical decomposition of phosphogypsum gives a gas rich in SO2. This gas is processed to obtain sulphuric acid, which is fed back into phosphoric acid production. The aim of this paper is to perform exergy analysis of the ...

Compacted lateritic soil treated with blast furnace slag as hydraulic barriers in waste containment systems

Laboratory testing was conducted to assess the feasibility of using lateritic soil mixed with up to 15% blast furnace slag (BFS) by dry weight of soil as a suitable hydraulic barrier. Tests were carried out on the lateritic soil-slag mixture to ascertain the particle size distribution, index properties and compaction characteristics. The relationship between hydraulic conductivity, unconfined ...

Experiences with anaerobic treatment of fat-containing food waste liquids: two full scale studies with a novel anaerobic flotation reactor

Fat-containing food waste can be effectively treated in a new type of reactor, the so-called BIOPAQ-Anaerobic Flotation Reactor or BIOPAQ® anaerobic flotation reactor (AFR). In the reactor a flotation unit is integrated to retain the sludge. In this study results from two plants with a 430 and 511 m3-AFR, respectively, are presented. In one reactor, which is fed with water ...

Geotube Containment and Dewatering technology was used to dispose of slurry waste from North River Mine - Case Study

At the North River Mine in Berry, AL, two waste streams are created from the processing plant, coarse rock and fine rock particles. Coming from the processing plant, the fine rock particles are suspended in water forming a slurry. This slurry is normally disposed of via surface impoundments or injected into abandoned underground mine workings. The volume of this waste stream is very significant ...
