RECYCLING, REUSE, TRADITIONAL KNOWLEDGE and INNOVATIVE TECHNIQUES to MITIGATE PLASTIC WASTE POLLUTION on CAMEROON COASTAL ZONES

Abstract

This research paper presents the results of recycling, reuse, traditional knowledge and innovation techniques aimed at mitigating
plastic waste pollution on the Cameroon coastal zones. The objective of this research work is to analyze qualitatively and quantitatively solid waste in the West Coast (Limbé) with the South Coast (Kribi), develop a technology based on local knowledge
from fishermen to build an ecological boat as well as evaluate local perceptions of the impacts on fishing and tourism. The
methodology consisted of beach surveys, interviews and questionnaires administered to fishermen, tourists to determine
perception, attitudes and belief on plastic marine waste The results showed a high pollution from plant debris (77.30%) followed
by plastics (20.9%) and organic food waste (1.8%) at Limbe Down beach in the Southwest and Londji in the South Regions of
Cameroon. There was no significant difference between the two regions regarding perception of pollution on the littoral coast.
Amongst the fishery stakeholders, 48% interviewed recognized an average reduction in income while 100% of hotel operators
revealed it has reduced hotel bookings The reuse and recycling process involved 850 PET bottles of one liter to manufacture an
ecological boat that measures 5.5m and capable of transporting three persons of 80kg each. This innovation used in Londji beach
for ecotourism has fascinated many tourists because of its originality. The study reveals that pre-collect, reuse, recycling and
traditional knowledge, besides being a primary strategy, is amongst the most effective techniques for reducing the quantity of used PET bottles disposed at our exotic beaches Limbe and Kribi.
