Ecodesign is a strategic design
management process that
considers the full life-cycle
environmental impacts of
packaging, products, processes,
services, organisations and
systems. It can identify layers of
waste and layers of value.

1. Introduction
Recently, the concept of the circular
economy has gained traction in industry
and policy as a pathway to deliver
While not a new concept clearly its
widespread appeal has never been
greater. This is because industry at
large recognises the need to transition
from a linear take-make-dispose
model of production and consumption.
A key driver for this is increasing
awareness of resource scarcity, risks
to business competitiveness and the
potential impact this may have in
the long-term. In a recent UK based
survey of 435 companies in total
72% indicated that they are looking
to engage with waste management
providers to collaborate and implement
closed loop systems (Edie, 2013).
Purported incentives and cost reductions
seen through circular economics are
gains claimed through implementation
of closed loop manufacturing systems.
One report commissioned by the Ellen
McArthur Foundation (2013) found that
adopting a circular economy approach
could save European manufacturers
$630bn a year by 2025. As global
demand for sustainable solutions reaches
unparalleled prospects for industry.
This brief position paper discusses the
importance of an ecodesign perspective
within a circular economy. Firstly,
we set out the main similarities and
circular economics. Following this we
discuss key challenges in implementing
circular economy principles within
alternatives to the circular economy
for long-term environmental
protection and social wellbeing.

also essential to recognise that there
are environmental impacts resulting
from product life cycle stages other than
raw material extraction (this includes
environmental impacts of recycling

role of ecodesign in bridging this gap.

impacts of a product right from the
earliest stage of design. In particular,
this avoids uncoordinated product
planning (for example, eliminating a
toxic substance should not lead to higher
energy consumption, which on balance
could have a negative impact on the
environment.” Traditionally, ecodesign
evolved to include services and systems
(see Sherwin and Evans, 2000).
Ecodesign strategies (such as design for
recycling, design for disassembly) can
facilitate closed loop remanufacturing
while also making ecodesign products
suited to servicing, leasing and hiring
options.
This means that like the circular
economy model, ecodesign often
requires business model innovation
to realise value invested earlier in the
design stage.

Operational Synergies
The practical relationship between
ecodesign and the circular economy
is acknowledged (e.g. Besch 2005).
Importantly, a large body of literature on
ecodesign practices exists including case
studies, ecodesign methods, strategies
and a substantial number of ecodesign
tools. This existing body of practical

Combined, these aspects require
fundamental changes in industrial
infrastructure, which is a key barrier
to implementation of ecodesign and
circular systems.
Diering Approaches
Ecodesign is central to closed
loop manufacturing and product
designers are at the forefront of
its implementation. While product
designers play a central role, there are

In addition, MBDC have also criticised

they propose material toxicity testing
as a preferable approach.Ideally, a
combination of both approaches is
desirable.
Ecodesign needs to be informed
by LCA results to allow design

to take action. In terms of material

proposes that material formulators

Fundamental Distinctions
It has long been stated that 80% of a
product’s environmental impacts are
determined at the design phase (Graedel
and Allenby, 1995). As previously
discussed, Table 1 illustrates how circular

Evans (2000) state ecodesign is ‘the
design of a product, service or system
with the aim of minimising the overall
impact on the environment’. This
distinction is important because resource

According to McKinsey (2011) circular
economics means ‘meeting current
demand/consumption needs’ (see
Table 1). In contrast, we believe society

4. Challenges to Closing
the Loop
The literature discusses a number of
challenges or barriers to achieving the
circular economy. Here, we discuss these
challenges according to three groups:

economic and infrastructure problems;

Practical issues surrounding the circular
economy are frequently cited and many
of these are also relevant to ecodesign.
practical problems. This is followed by
a discussion of issues that are more
economy.
4.1 Practical Issues
Supply chain management,
Logistics, Pricing and
Investments
Each of the possible routes for
maintaining materials in a closed system
has its own problems. For example,
companies struggle to implement
functioning distribution networks that
bring products from locations scattered
nationally or internationally to a central
depot. In addition, few regions have
the infrastructure in place to collect
unwanted products. These issues are
exacerbated by a limited ability to
predict quantities of returned products.
Furthermore, there is often poor market
demand for reused and remanufactured
products, in part related to consumer
perceptions of these products, their
quality and functionality. Other
binding contracts that may constrain
improvements to business operations,
Intellectual Property (IP) rights which
restrict information sharing along the
supply chain and issues around the
legalities of selling remanufactured
products (Kuo 2011; Souza 2012;
Vanegas et al. 2011).
In addition, the economic viability
and environmental impact reduction
through schemes to promote reuse
and remanufacturing (such as ‘product
take-back’) are dependent on a number
of factors. Most importantly, product
designs need to be durable enough to
withstand remanufacturing and multiple
cycles of use and Original Equipment
Manufacturers (OEM) need to be willing
or incentivised to take the product back
and service models are suited to non-
energy consuming products during the
impacts). Products also need to be
manufactured with standardised
materials to generate high value and
pure recyclate thus incentivising product
take-back (Kuik et al. 2012; Grant &
Banomyong 2010). Some businesses
may have also already invested large
amounts of money in machinery and
infrastructure for their production
processes, making required changes
uneconomical. Others may struggle
to raise initial investment funds to
implement improvements.
Businesses also need appropriate
remanufactured products. This is an
active and complex area of academic

Recycling and Externalities
Economic, infrastructure and technical
of recycling for some materials. For
example, although technically possible,
perform closed loop recycling for some
types of plastic due to the mixing of
contaminants such as ink and metals
in the recyclate (Hopewell et al., 2009).
Therefore, plastics are often down cycled
into products that require a lower quality
material. There are also challenges for
the recovery and recycling of metals.
currently exist for metals such as
aluminium and steel, the recovery rates
for other metals such as Rare Earths are
much lower (Ecodesign Centre Critical
recovery of these metals include very
low quantities in products, making it
of one metal type versus another in the
recovery process (Hagelüken & Meskers,
2009). A major challenge is ensuring that
metals from waste products enter into
the correct recycling pathways. Currently
a large quantity of end-of-life products
are traded abroad and processed

related to a problem with the true cost
of goods and services where the external
costs to the environment or ‘externalities’
are not included. This results in
goods and services being priced very
cheaply, making recycling and reuse
of materials uneconomical while virgin
material supplies are still plentiful.
This phenomenon prevails despite the
environmental impacts associated with
their production.
For these reasons ecodesign prioritises
long life durable products that can be
with limited additional process. This is
particularly important because easily
disassembled products with high
amounts of recycled content (therefore
suited to recycling) can often have
compromised durability (Prendeville
2014).
Behavior Change Issues and
Overconsumption
Achieving a circular economy requires
action from and communication
between a variety of stakeholders
including politicians, business managers,
investors, research scientists, designers
and everyday consumers. Changing
current modes of production and
consumption requires behavior change

amongst these groups. A large amount
of research has been undertaken on
pro-environmental behavior change
One major challenge is altering peoples’
habits to avoid activities that are
unsustainable (Kollmuss & Agyeman,
2002). On a business level, change also
requires leadership from owners and
managers.
Of particular concern in the literature,
linked both to general consumers
and businesses, is the occurrence of

Paradox, and therefore greater

(Polimeni et al., 2009) . Discussing these
phenomena with an economist uncovers
are gained. Therefore, focusing solely
products, threatens the sustainability of
the circular economy.
More Fundamental Challenges
to the Circular Economy
There are also limitations to recycling
and growth of the economy based on
material use that can be understood
from the second law of thermodynamics
(Ayres, 1998). This law recognises that
entropy (a measure of disorder) in an
isolated system always increases until
it reaches a state of thermodynamic
equilibrium (maximum entropy). If the
economy is considered as a closed
thermodynamic system , then materials
cannot be cycled continuously without
inputs of energy external to the system.
In the short-term limits to economic
growth based on thermodynamics
will not be an issue. Supplies of many
materials currently remain plentiful.
However, rapid economic growth that
is decoupled from environmental
degradation may be limited by the
environmental damage caused by mining
materials and an inability to source clean,
renewable energy at competitive prices.
In the longer-term thermodynamic limits
may mean that the circular economy
alone will not be a solution for a truly
sustainable society.
5. Alternatives to the
Circular Economy
There are other economic models that
have been suggested that are less
supportive of economic growth, due to
the limitations described above. But also
because there is evidence to suggest
that beyond a certain point economic
growth based on material use does little
to increase human well being (Jackson,
2009). Perhaps the most frequently cited
alternative model is the steady state
economy, where the size of the economy
is stable. For a steady state economy to
be achieved the throughput of materials
in an economy would need to remain
fairly constant, as would population.
A limit would then have to be set on
resource inputs to allow for a level of
economic activity that ensures good

measures may then allow for continuous
improvements in quality of life to be
made.
The other commonly cited suggestion
is sustainable degrowth. As the name
implies, this model aims for planned
degrowth of the economy to ensure
society lives within environmental limits.
from the steady state economy, some
commentators see the end route of
sustainable degrowth as a steady state
economy (Kerschner, 2010).
Moving towards a steady state economy
or achieving sustainable de-growth both
represent major challenges for society.
One of the largest barriers for either is
the fact that population would have to
remain constant or decrease. Currently
population is predicted to rise, reaching
around 9 billon people by 2050 (United
how resource inputs into the economy
could be limited and controlled on a
global scale and is important to note
that many countries still need economic
growth to lift them out of poverty.
Despite these challenges, a steady state
economy has long been suggested as the
endpoint of development of an economy
(Kerschner, 2010). Although it may be
should perhaps be a goal to strive
towards. The circular economy could be
used as a route to achieve this. Despite
it being a concept that is supportive of
economic growth, a circular economy
implemented using ecodesign principles
will allow for better quality of life while
reducing environmental degradation.
These changes may make it easier to
achieve a steady state economy in the
future, while being less at odds with
political and economic systems of the
present.
