2. Background 2
• The City of Johannesburg (CoJ) covers about 9.7% of the to
total land surface area of the Gauteng Province (16 927 km 2).
• Population of ~ 10 451 713 (Community Survey 2007).
• Generates 16% of South Africa’s GDP, employs 12% of the
national workforce, and houses 74% of national head houses.
• CoJ economy projected to grow by approximately 5% per
annum over the next decade.

3. The Joburg 2040 GDS paradigm 3
The Paradigm has
defined four
inter-related
drivers namely:
• Human and
social
development;
• Inclusive and
productive
economic
growth;
• Environment and
services Each of these concepts are interrelated in a
(including the sense that they may support the achievement
related of resilience, sustainability and liveability
infrastructure);
and
3
• Governance

4. Flagship Sustainability Projects 4
 Waste to Energy plant: 500,000 tons per year facility
(PPP underway)
 Rea Vaya Bus Rapid Transit (BRT) extension
 NMT master plan: city-wide bike path system
 Household rollout of solar water heaters
 Landfill gas to energy – 5 landfill sites (PPP underway)
 Wastewater biogas project

5. Biogas to Energy 5
– City has 5 major waste water treatments facilities that already in
some cases have biodigesters installed as sunk costs
– Joburg Water faces a R120m ($16m) annual electricity bill.
– Electricity tarriffs have gone up by 25% for 3 years in a row and are
expected to increase annually at 8-12% for the next 10 years
– Joburg Water can become 85% self-sufficient in the production of
energy from biogas at its wastewater facilities

6. Other benefits from the Biogas Project 6
– Source of Renewable energy
– Reduction of GHG emissions
– Soften the impact of increasing power costs
– Long term savings in electrical power costs
– Payback of capital invested over a relatively short period of
time
