Rwanda as a developing country, we are trying to keep our environment good and also to conserve forests for they are of great importance to us. But also we need to cook in order to sustain our bodies and hence it creates a matter of conflict with the green enviroment due to the fact of finding charcoal or firewood from these forests which ends up cutting them down an hence leading to defforestation and a time x we may end up in a desert, so we have to find a solution to produce energy in a friendly manner to the environment.
Also we need clean and renewable energy to thus thinking of a way to use kitchen wastes to produce biogas
Home biogas kit, is a solution to energy problems in our region where large number of people are using charcoal which is a porous black solid consisting of an amorphous form of carbon, obtained as a residue when wood, bone, or other organic matter is heated in the absence of air and also there's use of firewood
All these emmit some carbon in the air hence creating air polluttion
I came up with an idea of a portable or an easy to assemble/dis-assemble Home biogas kit, whereby after looking around in Rwanda all of those who have biogas are using a big scale of land to costract the biogas plant, so i started to think of people living in appartments in the urban areas and also a way of making it small and simple for assemling and dis-assembling the biogas plant
I also thought of leakage problems that may occur to cooking gas users so i decided to add to this Biogas kit a leakage gas sensor that sends an alarming sound in case of gas leakage so as to prevent accidents. I also thought of adding a Liquid Crystal Display(LCD)Screen
Procedures for Homebiogas kit construction
Concept
The project reviewed here is one of the few and first scale of this kind, that begins to tap into the immense of Rwandan bioenergy generation potential.
The aim of this project is to produce sustainable biogas kit for biogas generation from kitchen waste.
Since the project is the first of its kind in the country learning from its development will be well documented to assist in further developments.
Research
In Africa, water pollution and access to energy resources
present challenges to human health, environmental
health, and economic development. In 21 sub-Saharan
African countries, less than 10% of the population have
access to electricity. The need for alternative renew-able
energy sources from locally available resources can not
be over emphasised. Appropriate and economically
feasible technologies that combine solid waste and
wastewater treatment and energy production can simultaneously
protect the surrounding water resources and
enhance energy availability. Biogas technology in which
biogas is derived through anaerobic digestion of
biomass, such as agricultural wastes, municipal and
Industrial waste (water), is one such appropriate
technology Africa should adopt to easy its energy and
environmental problems. Anaerobic digestion consists of
several interdependent, complex sequential and parallel
biological reactions in the absence of oxygen, during
which the products from one group of microorganisms
serve as the substrates for the next, resulting in
transformation of organic matter (biomass) mainly into a
mixture of methane and carbon dioxide
After material selection it was easy for me to decide which machine to use, so i chose to use a Computer Controlled Machining process(the shopbot).whereby i cutted and did the pocketting according to the design using this Machine. I imported the DWG files which the Vcard reads since the Vcard is the software used on this shopbot.
The Piping from the digester feeder to the digester i used a wrapped paper and added a composite on it so that it may be strong and capable of not being carried away with liquid.
I designed a board for a gas leakage sensor(MQ5) whereby after gas production the sensor will be sensing the leakage and send a message to the Liquid Crystal Display(LCD)Screen
