Study Notes

Circular Supply Chains

Cradle-to-cradle circular way prioritizes reuse and keeps products intact
Circular systems are preferred as they preserve products, unlike linear cradle-to-grave systems
Supply chain management involves steps from supplier to customer
Upstream refers to the supplier side, while downstream is the customer side
Conventional supply chains have one-way flow of products and finances
Return management in conventional supply chains includes commercial returns (linked to sales), reusable items (related to consumption), and end-of-life returns avoiding negative externalities.

Reverse Supply Chains

Forward supply chains end with the customer, while reverse supply chains reverse the flow to capture value from earlier stages
Reverse supply chains encompass more than just returns management; they involve marketing and logistics across the network
Reverse supply chain steps involve planning, implementing, and controlling the flow of raw materials and finished goods from the point of consumption to origin
It's crucial not to consider reverse supply chains only as a returns management issue; rather, it's a full product lifecycle approach.

Complexities of Reverse Supply Chains

Coordination challenges
Conflict between stakeholders (interest actors)
Intrinsic complexity of the process
Regulations impacting operations
Managerial oversight issues

Circular Business Models and EOL Product Management

Circular business models address product returns and encompass many product types.
Products might not be ready for circular management at the end of their lifecycle
Many factors make product circular management challenging (e.g., complexity of product types, lack of circular product design)
Often, the focus is on operational aspects rather than strategic aspects in circular management

Prerequisites for Successful Closed-Loop Supply Chains

Legislation is required to drive and support efforts that benefit sustainability
Collaborative supply chain relations with partners is a crucial factor
Businesses creating closed loop products should ensure proper supply chain networks.

Linking Business and Design Strategy

Companies need appropriate business model innovation to produce longer-life products
Product design strategies need to consider ease of maintainance and repair, dis/reassembly to maximize the product lifecycle
Distinguish products (of service) from products (of consumption) for better planning
Identify closed-loop supply chain complexities involving returns and maintenance

Industrial Symbiosis

Industrial symbiosis uses waste materials from one company as inputs for another
It aims to create a more circular approach to industry practices
Challenges of industrial symbiosis include uncertainties in the quality and quantity of waste materials
Waste availability issues are often solved with proper regulation and incentives
Efficient management of industrial symbiosis requires cooperation among different parties.

Energy-Based Industrial Symbiosis

Energy-based industrial symbiosis involves one process's waste energy being used by another
It includes cascade, fuel replacement, and bioenergy production
Careful planning is needed, as different types of industrial symbiosis have various impacts

Sustainable Business Model Canvas

Circular economy minimizes environmental impacts, optimizes resource use, and extends product lifecycles
Business models should aim at low environmental impact and use minimized resources.
Companies need to think about preserving and conserving resources for a truly sustainable outlook.

Value Proposition

Value propositions are central to businesses.
They address customer needs and wants along economic, social, and environmental dimensions.
Effective propositions must effectively address customer needs and deliver value within economic, social, and environmental contexts.
Businesses are driven by innovation; this is essential to create value proposition and remain competitive while addressing future needs.

Business Model Innovation (BMI)

Business model innovations aim to improve existing models or create entirely new ones
Critical reasons include responding to crises to safeguard businesses, adapting to environment changes, bringing new tech/products/services, and creating new business models to enable future preparedness.
Key challenges to innovation include resistance to change, misalignment between innovation development and business goals, and difficulties inducing wider market acceptance of new concepts

Environmental Impacts, LCA

Life cycle assessment (LCA) tools are useful in assessing environmental impacts throughout a product's lifecycle.
LCA encompasses a variety of processes, from production to use and disposal through a defined scope.
LCA involves considerations across all stages of a product's lifecycle (production, use, disposal) and their associated impacts.
LCA results facilitate well-balanced decision-making processes with a focus on environmental and economic factors.
