Abstract:
Waste management is crucial due to the fast increase of human population,
causing an increase in solid waste generation which if not properly managed
causes environmental problems. Around 57% of the wastes generated from
homes are made up of green material (fruits, vegetables…). Thus, reusing and
recycling green wastes through composting is one way of reducing the waste
load to landfills. Composting is the transformation of raw organic materials
into organic soil amendments that provide nutrients to crops and enhance
the tilth, fertility, and productivity of soils. Aerobic windrow composting system
at Sukomi Greensite facility located at Karantina is performed, where
materials biodegrade under controlled conditions to produce compost. However,
assessment of the quality of the compost is fundamental in order to determine
its usages. Thus, regular testing of physical, chemical and biological
parameters was performed for adequate monitoring purposes. The basic objective
of this study was to determine the characteristics of the Lebanese municipal
solid waste compost on a yearly basis and compare these characteristics
amongst the years. Hence, each parameter was tested and compared to
the BNQ international Canadian standards for proper classification of the
compost and adequate identification of its usages. The preliminary data obtained
were statistically diagnosed through principal component analysis by
Spadv55 software. All the data reflected the normal content value of the studied
parameters with minor differences between the years except for year
2007 which demonstrated higher levels of Potassium, Phosphate, Lead and
Cadmium. The characteristics of the compost enabled it to be used as a soil
amendment on all types of agricultural and landscape commodities at the
adequate dosages and proper timing. This data will additionally reflect the efficiency
of the solid waste management practices adopted via highlighting the
importance of the implementation of the integrated solid waste management
practices.
