1.1 OVERVIEW OF BIOGAS TECHNOLOGY
What is biogas Technology:
This is a system that makes it possible for organic matter to be broken down under oxygen free condition ,which results in production of biogas.
➢ The biogas is a biofuel which is used to power generators for production of electricity.
➢ It is also used in the kitchen as energy for cooking.
➢ The treated effluent from the biogas system is used as manure on the farms for food production.
BIOGAS TECHNOLOGY & UTILISATION IN GHANA.
Historical Background:
➢ Biogas Technology was given the needed attention by
the Government of Ghana in the mid 1980s.
➢ Ghana entered into a cooperative agreement with China
in 1986 on dissemination of biogas Technology in
Ghana.
➢ This agreement resulted in the construction of 33 biogas
digesters of various capacities in Ghana.
33 digesters were constructed in Appollonia, a cattle rearing Village in the greater Accra Region
1 was constructed at the Bank of Ghana cattle ranch in Shai hills.
In 1987 UNICEF sponsored the construction of two biogas digesters in the Northern Region of Ghana
The Objective of all these projects was to provide energy for cooking.
BIOGAS TECHNOLOGY & UTILISATION IN GHANA.
Historical Background:
In 1992 the ministry of Energy commission , under the
Appolonia Integrated Rural Energy Project constructed
Biogas plant for electrification purpose.
After this project government’s involvement in
dissemination of biogas technology dwindled.
The mantel for promotion of biogas technology was
taken over by NGOs and private businessmen.
BIOGAS TECHNOLOGY & UTILISATION IN GHANA.
Historical Background:
MOTIVATION FOR BIOGAS TECHNOLOGY AND
UTILIZATION IN GHANA
Reduction of Expenditure on Liquid waste
Management: Over 2000 Private companies in Ghana
have constructed hundreds of biogas digesters for
households, hospitals, schools , hotels and other
institutions.
Their major aim is to reduce the cost of dislodging the
traditional septic tank. A household in Ghana spend an
average of USD 318 equivalent annually on dislodging
of septic tank.
Reduction of Expenditure on LPG: The second major aim of household, hospitals, schools, hotels and other institutions for using biogas technology is to use the biogas for cooking thereby reducing their expenses on LPG. A household spend an equivalent of USD350 annually on LPG.
Provision of Electricity : Some Agro processing companies have used Biogas technology to provide electricity for their operations.
MOTIVATION FOR BIOGAS TECHNOLOGY AND
UTILIZATION IN GHANA
REGULATORY FRAMEWORK FOR BIOGAS
TECHNOLOGY AND UTILISATION IN GHANA
In 1997, The Energy commission was established by an act of Parliament (Act 541), with the objective among others to develop , regulate and manage renewable energy sources in Ghana.
Ghana renewable energy sources are wind, solar and Biomass and Waste. Accra Metropolis generates an approximate of 2000 metric tons of waste per day
In 2011 the Renewable Energy Act 832 was promulgated.
The Act provides a framework :
▪ to support the development and utilization of renewable energy sources;
▪ That ensures enabling environment to attract investment in renewable energy sources;
▪ for promotion of use of renewable energy;
▪ For diversification of supplies to safeguard energy security.
REGULATORY FRAMEWORK FOR BIOGAS
TECHNOLOGY AND UTILISATION IN GHANA
THE BIOGAS MARKET IN GHANA
Biogas technology and utilization is growing at a very fast rate in Ghana.
The market consists of :
▪ The households,
▪ Institutions (Hospitals, Schools, hotels etc)
▪ Agro processing companies
▪ Metropolitan & Municipal Assemblies
▪ Independent Power Producers.
➢ HPW Fresh and Dry Ltd Biogas Plant
Lavender Hill –Sewage Treatment Plant
Safi Sana Biogas Plan
Central University- Biogas Digesters
CASE STUDY OF BIOGAS TECHNOLOGY &
UTILISATION IN GHANA.
➢ HPW Fresh & Dry Biogas Plant.
>HPW is a fruit processing company located
in Adeiso .
>Two 450m3 concrete biogas digesters
and three 100m3 gas holders.
500m3 of biogas averagely generated daily.
> Effluent channeled to the farm.
>Feedstock : fruit waste.
Lavender Hill Sewage Treatment Bio Gas Plant.
This is Sewage treatment plant run by Sewage System Ghana under a partnership agreement with Local Government and Rural Development. The Government pay SSG Management fee.
The plant is located in Accra and started operation in November 2016.
The main Objective is to stop dumping raw human waste into the sea.
Secondly to Generate electricity to feed the national grid as a supplement.
It has a maximum treatment
capacity of 2400m3 liquid waste
per day.
It currently generate 0.5 megawatts
of electricity , used solely for its
operations.
Estimated Cost of the facility was
$25million .
Estimated payback period -
15years.
Lavender Hill Sewage Treatment Bio Gas Plant.
Biogas plant
Safi Sana Biogas Plant :
Safi Sana is an independent power producer
100kVA Generator
The plant became operational in 2016.
It has a total capacity of 2500m3
It treat about 9 tone of waste a day
➢ It Generates 1.6megawatt of
electricity per day Biogas Digester
Power sold at $17.5/h to GRIDCO
Central University Biogas Plant
> This is three 100m3
Digesters constructed in 2008
> Used solely for human
waste Management.
BUSINESS MODEL OF ARETECH
The Motivation for setting up ARETECH.
▪ The passion to assist in promoting healthy environment, by reducing dumping of raw sewage into the sea and open defecation.
➢ Core Value :
➢ We provide customers with the most efficient way of treating their sewage and freedom from dislodging .
➢ We achieve this by designing and constructing biogas digesters for households and institutions in Ghana at an affordable price (Price range $1370 - $5000).
CONCLUSION:
Biogas Technology is the surest answer to waste
management problems in Africa and the world as a whole.
All the landfill sites in Nigeria, Ghana and other countries
are resources and not nuisance.
The days of pumping raw human waste into the sea is over.
I will therefore call upon my government, Nigeria
government and all African governments to engage the
stakeholders in the biogas industry to design a
comprehensive program to turn the waste to wealth through
the power of BIOGAS TECHNOLOGY.
