Developing business opportunities for resource
recovery and reuse (RRR) of domestic and agro-
industrial waste
Dr. Solomie GebrezgabherDr. Avinandan Taron
RRR impact and upscaling project stakeholder workshopJune 11, 2015, Ghana
Urbanization and consumption levels
• Increased urbanization coupled with increased consumptions
levels Significant waste generation
• Cities are becoming vast nutrient sinks while exploiting soils
in farming areas
• Waste generated ends up in open dumps and natural water
bodies Environmental and health challenges
Changing waste challenge into an opportunity

Reuse is not new
• Efforts have often been limited in size, hardly going beyond
the pilot scale
– Waste not viewed as a resource
– Lack of business thinking a bottleneck for attracting
private capital and scaling up reuse of waste
• Need for innovative solutions apply a business perspective
Agro-industrial waste - Energy
Wastewater – Water(irrigation, aquaculture)
MSW, Faecal sludge - Nutrients (ag. production)
Innovative reuse initiatives

Identification of 150+ RRR
potential success stories across Asia, Africa and Latin America
and analyzing 60+ in detail.
RRR-impact and upscaling project
Two components:
1. Assess the business environment
(investment climate) for RRR sector
2. Assess the economic impact of RRR
businesses
Business environment for RRR
• Waste management strategies shift focus from a disposal-oriented
approach to a business-oriented approach that emphasizes value
creation and revenue generation
• To achieve success in RRR sector, there is a need for private sector
involvement
• Need for understanding of the business/investment climate under which
the RRR businesses are operating to foster entrepreneurship in RRR
Defining business environment
• Business/investment climate comprise all factors external to firms (policy,
legal and regulatory frameworks; macroeconomic policy; financial access
etc).
• A good investment climate (IC) is central to private sector led growth and
investment
Employment generation, income growth, poverty reduction
Need for IC assessment• Assists Governments/policymakers to identify which
dimensions of the IC need improving.
• Inform Investors/businesses the business environment they
are operating in.
• Assist Donor community to identify specific issues and
develop targeted private sector development programmes.
Framework for assessing IC for RRR
RRR Entrepreneurship determinants
Regulatory framework& Infrastructure
•Cost to start a business•Tax incentives•Access to infrastructure
Markets
•Market size•Domestic sales
Support service
•RRR Network associations•RRR incubators
Finance
•Access to debt•Amount of bank loans to RRR•Interest rate
RRR entrepreneurship performance•Number of RRR firms (birth, death and survival rates)•RRR firm growth rate

• Why do we need ecosystem services approach?
– Primarily to meet the needs of sustainable production and consumption
• What are ecosystem services?
– Benefits people obtain from nature – it comprises of the dynamic
interactions between the living and the nonliving environment
• Inclusion of both natural and human-modified ecosystems
• “Services” encompass both tangible and intangible benefits
• How can we classify ecosystem services?
– The Millennium Ecosystem Assessment (MA)
– The Economics of Ecosystems and Biodiversity (TEEB),
– The Common International Classification of Ecosystem Services
(CICES)
The Ecosystem services approach
Defining Ecosystem Services
Provisioning services –
• Food , raw materials, fresh water and medicinal resources
Cultural services –
• Recreation
• Tourism
• Aesthetic appreciation
• Spiritual experience
Habitat or supporting services –
• Habitat for species &maintenance of geneticbiodiversity
Regulating services –
• Local climate and air quality
• Carbon sequestration and storage
• Moderation of extreme events
• Wastewater treatment
• Erosion prevention and maintenance of soil fertility

Valuation of ESS
Methodology
Quantify the impacts of policy options
Approaches in theImpact Assessment
(i) Environmental Impact Assessment,(EIA); (ii) Strategic Environment Assessment, (SEA);
(iii)Life-Cycle Analysis (LCA); (iv) Risk Assessment;
(v) Cost-Effectiveness Analysis; (vi) Multi-Criteria Analysis (MCA) and
(vii) Cost-Benefit Analysis (CBA)
Assess the effects on welfare
Establish Environmental baseline
Qualitative Assessment
Valuation of ESS
• The preliminary activity involves Scoping followed by Screening of the environmental impacts
• Use of a ranking methodology, expert opinion, secondary review for each of the services
