Index for the assessment of municipal solid waste management in Angola: a case study in kuito, bié province
(2021-01-01)
The present work aimed to evaluate the efficiency of the municipal solid waste (MSW) management system in Kuito, Angola, using an efficiency index (MSWEI) adapted to African conditions. Four dimensions constitute MSWEI: ...
Pectinase production by Penicillium viridicatum RFC3 by solid state fermentation using agricultural wastes and agro-industrial by-products
(Springer, 2002-10-01)
Pectin lyase and polygalacturonase production by newly isolated Penicillium viridicatum strain Rfc3 was carried out by means of solid state fermentation using orange bagasse, corn tegument, wheat bran and mango and banana ...
Phytotoxicity and cytogenotoxicity of composted tannery sludge
(2020-09-01)
Tannery sludge (TS) contains high levels of organic matter and chemical elements, mainly chromium (Cr). This can increase its toxicity, rendering it unsuitable for application to soil. However, composting has been proposed ...
Anaerobic co-digestion of animal manure at different waste cooking oil concentrations
(Univ Federal Santa Maria, 2018-01-01)
This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of ...
Construction and demolition waste in concrete: Property of pre-molded parts for paving
(2019-01-01)
Construction and demolition waste (CDW) production is a growing factor on a global scale and its incorrect disposal becomes an increasingly common problem in cities. It is estimated to represent, on average, 50% of the ...
Case study: a 3D resistivity and induced polarization imaging from downstream a waste disposal site in Brazil
(Springer, 2012-06-01)
A contaminated site from a downstream municipal solid waste disposal site in Brazil was investigated by using a 3D resistivity and induced polarization (IP) imaging technique. This investigation purpose was to detect and ...
Integral transform analysis of radionuclide transport in variably saturated media using a physical non-equilibrium model: Application to solid waste leaching at a uranium mining installation
(2020-01-01)
The Generalized Integral Transform Technique (GITT) was employed to simulate transient one-dimensional flow in variably saturated porous media, as well as radioactive waste transport within different layers (a solid waste ...
