Sebastião Roberto Soares et al.
Waste management (New York, N.Y.), 33(1), 175-183 (2012-11-06)
The establishment of rules to manage Health Care Waste (HCW) is a challenge for the public sector. Regulatory agencies must ensure the safety of waste management alternatives for two very different profiles of generators: (1) hospitals, which concentrate the production
María Nazaret González-Alcaraz et al.
Journal of environmental management, 116, 72-80 (2013-01-08)
The aim of this study was to identify the effectiveness of liming in combination with vegetation for the recovery of slightly acidic, saline soils of eutrophic wetlands affected by mine wastes, under fluctuating flooding conditions. Simulated soil profiles were constructed
Vasilije Manovic et al.
International journal of environmental research and public health, 7(8), 3129-3140 (2010-10-16)
This paper presents a review of the research on CO(2) capture by lime-based looping cycles undertaken at CanmetENERGY's (Ottawa, Canada) research laboratories. This is a new and very promising technology that may help in mitigation of global warming and climate
