Urban solid waste management systems (MSW) in developing countries are characterized by inadequate service delivery, low waste recovery, operational inefficiencies and inadequate waste disposal.

Eucalyptus globulus forest residues, bark, and branches, were characterized by wet chemistry methods and involved in the liquefaction process using a glycerol-ethylene glycol reaction mixture (1:1, v/v) catalyzed by strong mineral acid (3% H2SO4) or strong mineral base (6% KOH). The effect of the reaction conditions (temperature and duration) and the particle size on the yield of liquefied products have been ev...
While the municipal solid waste management systems (MSW) dominated by the informal sector makes positive contributions to the environment, they are also characterised by inadequate service delivery, low waste recovery, operational inefficiencies and inadequate waste disposal. The presence, of municipal solid waste poses a threat to public health and the environment if not managed properly. Tocoloa, Martinho and...
