2.4.1 Household Solid Waste (HSW)
Household solid waste otherwise called domestic waste is a component of MSW. They are wastes generated from domestic sources, representing more than two-thirds of municipal waste volume
(OECD, 2001 in Adamcova, et al, 2016; Slack, et al, 2005). The composition of household solid waste in a municipal area depends on certain characteristics like, per capita income, societal lifestyle, industrialisation, institutionalism and commercialism (Jouhara, et al, 2017). This implies that, certain types of HSW would be peculiar to certain localities. Similarly, the volume of HSW generated in a household per day depends on the size of the family (Thrang, et al, 2016).
HSW mainly contains paper, plastics, glass, metals, textiles, diapers, organics, packaging materials, wood, some hazardous waste like batteries, electronic waste, paint, garden pesticides, etc (Hakami & Abu Seif, 2015; Slack, et al, 2005; Ojeda-Benitez, et al, 2008). It is pertinent to mention here that, some of these wastes can be recycled, some are not recyclable while some are hazardous hence the global advocacy for sustainable solid waste management, to ensure that what can be recycled is not lost in the waste stream byway of landfilling without sorting at source, or indiscriminate dumping at unapproved sites, thereby creating environmental hazards.
