Vanadium (ehc 81, 1988)

Waste hydrochloric, nitric, hydrofluoric, and sulfuric acids from a steel smelting plant contained 0.02% vanadium. the solid residue on the bottom of the acid vats contained 2.4 g vanadium/kg (hydrochloric acid vat) and 1.6 g vanadium/kg (nitric and hydrofluoric acid vats) (kurmaev, 1974); vanadium in waste acid that is not properly treated may

according to the construction and demolition debris disposal site guidelines, c&d facilities and debris disposal sites must receive approval before beginning operation, and they may only accept c&d waste unless approval is given by the minister to accept other types of waste (nsel, 1997) the solid waste-resource management regulations (swrmr

an equivalent amount of waste rock is removed from the mine each day. ore and waste rock are transported within the pit to the adjacent waste rock disposal areas by haul trucks with capacities as large as 240 tons. about 80 percent of the ore is hauled to the in-pit crusher and then conveyed to the copperton concentration for grinding and

Rapid removal of atmospheric co2 by urban soils

The measured calcium carbonate content of soils to a depth of 100 mm at a large urban development site has increased over 18 months at a rate that corresponds to the sequestration of 85 t of co2/ha (8.5 kg of co2 m–2) annually. this is a consequence of rapid weathering of calcium silicate and hydroxide minerals derived from the demolition of concrete structures, which releases ca that

mar 11, 2021 construction and demolition waste (cdw) substantially contributes to environmental degradation because of its intrinsic characteristics of fast and high generation volume, low recycling rate, and low revenue margins. a systemic problem is that recycling facilities are not usually a part of a reverse supply chain (rsc) specific for cdw.

jan 20, 2012 the energy and material flows of a city are often described as urban metabolism (um), which is put forward as a way to link a city’s ecology and economy. um draws parallels to the biology of individual organisms, yet the analogy is misapplied. in striving to be interdisciplinary, um makes this organismic comparison rather than identifying the city as an ecosystem, thereby ignoring
