5.3 Recommendation
On the basis of the findings and the conclusion of the study, the
following recommendations are made:
5.3.1 Minimization
- To promote the use of the water hyacinth, the supply constraints can
be resolved by making raw materials available on school grounds.
- Apply known technical solutions including insulation, solar tent,
solar heated feed water, and compost around digester, add urine/water
hyacinth, build digester under shed, and heat with biogas or engine
exhaust heat.
5.3.2 Further research work should be carried out to
investigate:
- The quantity, quality and composition of biogas produced vary from one
animal waste to the other. So, also biogas produced from agricultural
waste varies from that of animals. For this reason, investigation of
the quantity, quality and composition of biogas produced from
agricultural wastes is imperative.
- Issues involving the recovery of biomass energy and the decisions
concerning the promotion of biogas technology in order to replace
firewood should be further researched so as to be employed on a large
scale basis. Finding a reliable alternative to the excessive
dependence on electricity continues to pose a challenge that the
promotion of methane fermentation technology might help resolve.
- The creation of a biogas market, led by private contractors and run by
youths, which will most likely contribute to the popularization of
biogas technology for domestic purposes and job creation.
