Circular Design redesigns products to prolong life, minimize waste and potential loss of technical (man-made) materials. This means company’s can design a product that has certain functionalities to ensure components can be reused, materials can be reprocessed and breakages can be repaired. Here are some examples of how designers and entrepreneurs develop and exploit goods, helping reduce material (natural and man-made resources) and energy consumption over time¹.
Circular Design Workshop
Designing waste out of products as part of the Circular Rs framework is where the circular economy really comes into play. Visit the Circular Design Workshop page to find out what is covered in this class.
We have a selection of workshops to choose from, starting with our ½ day mini series for busy people or the deep-dive 1 or 2 day workshops. Visit The Nine Steps Towards a Circular Business® to review the current selection of workshops on offer.
Design Value Chain
Circular design principles provide value throughout the whole manufacturing, sales and use process for both businesses and customers. To maximise value and profit, companies can consider adapting their manufacturing/sales model to retrieve assets (products) through reverse logistics or Product-as-a-Service business models. Or seek alternative revenue streams to keep customers engaged and loyal such as providing upgrades or repair services.
In a circular economy model, every circle returns to an earlier point in the product life cycle, which is effectively the reuse of a product, component or material. Direct reuse by reselling/redistributing where a product is used for the same purpose without any changes becomes part of the business model and not of product design. However, such a business model will make the longevity of products more attractive.
Refurbishing is the practice that is less than remanufacturing but more than repair. Comparing to repair, the quality becomes more valuable by partly substituting broken components to reach the replaced/repaired modules or parts.
Df Repair & Maintenance
Maintenance focuses on assessing the performance and services of products to retain the functionality of the serviced parts; repair restores a product or component to good condition after decay or damage with an assurance for the repaired part.
The return of a used product to at least its original performance with a warranty that is equivalent to or better than the newly manufactured products. The practice is a comprehensive process of restoring activities (mainly under the test, inspection, full disassembly, refurbishment, part replacement, clean and reassembly).
Products and their parts can be separated and reassembled correctly, includes separating materials that are specific for different cycles in a circular economy.
The function of reprocessing consists of material recovery at end of-life and is the last option to recover any remaining value that a product or component has. Recyclability is determined primarily by the choice of materials (although this also depends on developments in the recycling industry) and the extent to which components / materials can be separated from each other.
Life Cycle Assessment
Customer Value Proposition
During the design process, the customer value proposition and business models for all future use cycles should be consciously built into the product. Designing circular customer value propositions requires designers to also consider several different strategies and their consequences on the product and service system design. For example in a Product-as-a-Service business model “Your responsibility as a (supplier) of the product does not stop after the sale. You have to keep that in mind as a designer of the product”².
Circular products that are part of an integrated business model focusing on the delivery of performance or function may be a better value proposition for many customers. Competition is based on the creation of added service value of a product, not solely on its sales or price value.
Durability includes the longevity and functionality of a product to extend the lifespan but also how to design emotional attachment to a product to make users unwilling to discard is another design strategy.
A product's value in terms of robustness and performance that is maintained over time and with fair use. Quality has a broader meaning beyond the word description from a customer's perspective. The quality of a product is associated with the variability of functionality based on product features and performances.
The design lasts over time as styles and colours are classical, and the materials age well.
Products that are easily personalized or customizable offer an opportunity to create a deeper emotional bonding between the user and the product, thus prolonging the use.
Df Recovery & Reprocessing
If products are part of a service, there may be incentives to return them to the provider after use, avoiding stocks of obsolete products in households, landfill or illegal dumping.
Design + Business for the Circular Economy
The aim of good design is, hopefully, destined for use in our everyday lives. Traditionally products were designed for sale in our old linear economic systems where they were simply products to be used and then discarded at end-of-life. As we move into Circular systems, design now takes on a whole new relationship with business. The design of products has the potential to become the business model.
In the opposite Business Model diagram Circular design principles can be included into almost every stage.
1. In the early stages of product design, the focus is on how durable, repairable, and how easy it is to dis- and reassembly and upgrade.
2. During the manufacturing process, raw materials can include materials recovered for reprocessing through recycling collection systems or returned via reverse logistics.
3. The value proposition of the product to the customer (ease of repair, durable, take-back incentive, etc) can be communicated via a company’s sales and marketing efforts.
The Guidelines for Design
To describe a circular product design framework, a set of definitions needed to be developed that are all-inclusive, fully applicable to product design and with a single interpretation of the terminology used³. The Butterfly diagram (opposite) has been adapted from the original Butterfly diagram to be more reflective for Circular Product Design Modelling
