BACKGROUND
• The use of waste as a resource has led to: Ø Decrease dumping and burning Ø Development of recovery techniques Ø Research into new and emerging technologies Ø Transfer of knowledge globally

• Value addi>on necessary because of: Ø Poor environmental sanita>on – outbreak of diseases, flooding
Ø Scarcity of land for dumping Ø NIMBY Syndrome Ø Economic benefits § Poten>al source of energy § Raw material

Why Biofuel: • Potential Replacement of fossil fuel due to: Ø Emission of GHG Ø Non-Renewable source Ø High Subsidies paid by governments • Opportunity to add to Global energy needs • Effective means of handling MSW- Ø Residual use as fertilizer

Factors influencing successful waste management include:
– Political will to implement set of policies – Investment and use of appropriate
technology – Involvement of individuals/people – Cost recovery /funding (Market forces)

Opportuni>es Investment in need • Technology-‐Recycling, bioenergy, collec>on,etc
• Equipment-‐ Haulage, recovery or recycling • Knowledge transfer • Capacity building • Research

BIOFUEL AND COMPOST PRODUCTION PROJECTS IN GHANA
Landfill gas capture programme outlined –Old landfill sites
![Page 12: Mie Kodwo - From 'Burgers' to Biofuels](https://reader033.fdocuments.net/reader033/viewer/2022051514/54bfd05d4a79595d628b456b/html5/thumbnails/12.jpg)
Liquid waste Mostly decentralization
Biogas dry fermentation (MSW/solid waste)
Decentralized Centralized

ZL/KNUST/DTU Biofuel Research project • Using MSW to produce Biofuel (Biogas and Bioethanol)
• Residual incorpora>on for soil amendment
Accra Compost Project • Accra compost plant - Project started by
Zoomlion Ghana Ltd, a private company (ZL), now absorbed by government
• Will be operational mid of July, 2012

• Community/Household based composting development project-Undertaken by a team from ZL
– Facility design-Plastic barrel container – Pilot- premises of Zoomlion Ø Prior to project activity – Source separation – Collection plan

BIOFUEL POTENTIALS
• Biological carbon source materials –poten>al for biofuel produc>on
ü Cellulose, sugars, hemicelluloses, fats and oils, lignin
• 1st Genera>on-‐Crops or conven>onal starchy food: Less sustainable because of food security
![Page 23: Mie Kodwo - From 'Burgers' to Biofuels](https://reader033.fdocuments.net/reader033/viewer/2022051514/54bfd05d4a79595d628b456b/html5/thumbnails/23.jpg)
2nd Genera>on-‐ Crop residues, energy crops of no food value and MSW.
ü Much sustainable, but depend on availability 3rd Genera>on The use of algae-‐ much more sustainable, no immediate alterna>ve use
![Page 24: Mie Kodwo - From 'Burgers' to Biofuels](https://reader033.fdocuments.net/reader033/viewer/2022051514/54bfd05d4a79595d628b456b/html5/thumbnails/24.jpg)
2nd Genera>on
• Usually cellulosic technologies – woody biomass-‐
The use of MSW now considered-‐poten>al components being: papers, plant materials, biodegradables, etc
Main challenge has to do with Pretreatment of the waste for the biofuel produc>on
![Page 25: Mie Kodwo - From 'Burgers' to Biofuels](https://reader033.fdocuments.net/reader033/viewer/2022051514/54bfd05d4a79595d628b456b/html5/thumbnails/25.jpg)
CHALLENGES
• Lack of funds to pilot research findings • Lack of facili>es for advanced research • Uncertain>es of market for recycled products-‐ no promo>on made so far
• Lack of promo>on from government
![Page 26: Mie Kodwo - From 'Burgers' to Biofuels](https://reader033.fdocuments.net/reader033/viewer/2022051514/54bfd05d4a79595d628b456b/html5/thumbnails/26.jpg)
ADVICE TO THE YOUTH • Encourage team work • Posi>oning to take full advantage of posi>ve opportuni>es
• Global networking and projects • Advocacy • Build capacity of members or individuals • Liase with poli>cal and governmental bodies to project the youth
• Research must be the focal point
