LEAN AND SUSTAINABILITY: How Can They Reinforce Each Other?Rudy Gort
Abstract
The purpose of this dissertation is to find out whether sustainability can introduce lean to companies in situations other than a crisis. The project also looks at how lean, as a proven management system, can support sustainability in becoming economically more attractive.
This dissertation starts with an extensive literature review, first about lean, followed by sustainability. It looks at: definitions, reasons why, how to, and barriers. Then a combined literature review focuses on: the communalities, potential conflicts, and how lean and sustainability can support one another. Each chapter concludes with a conceptual framework where findings are summed.
The research approach is both deductive (literature review to develop a theoretical position) and inductive (data collection and analysis). The main research design is an exploratory study based on comparative case studies. For this both a Lean Change Agent and an Environment, Health & Safety Manager were interviewed at three multinationals.
The findings show that lean is mainly used for its practical guidance, by using its tools and techniques, while also helping to make the broad concept of sustainability more tangible. However, without adopting lean’s long-term philosophic base, its utilisation remains superficial and is less likely to have a long lasting impact.
Sustainability hardly provides any other incentives for lean than financial ones. Although an extra constancy of purpose is not offered by sustainability, the emerging economic urgency may create a useful tide for lean.
As such this dissertation still provides enough arguments for both lean and sustainability implementers to stand stronger together facing mutual issues.

Sustainable Manufacturing Practices Through the Use of Lean Techniques
Lean Manufacturing techniques and tools can also be applied to green initiatives. When applied correctly, Lean principles can help individuals see the big picture and long range impact that a green initiative is having on both the environment, workers, and a company’s operation by helping apply appropriate costs to the longer term return on investment.

MOBILE PHONE DESIGN STRATEGY
This case study examines ecological impacts and equivalent CO2 emissions for mobile phone
components, assemblies and life cycle phases to determine if 'eco-friendly' practices offer
impact reductions. While ‘eco-friendly’ practices offer reductions in ecological impacts, they do
not significantly reduce equivalent CO2 emissions relative to phones not marketed as ‘eco-
friendly’. Furthermore, it appears the most effective ‘eco-friendly’ practice is to reduce power
consumption.
Significant Results:
recycled plastic housings reduces ecological impacts up to 50%
recycling offers 66% reduction in ecological impacts
Recycled packaging and instructions scenarios result in more
than 90% reductions in
equivalent CO2 emissions
use-phase ecological
impacts and equivalent

following study takes a closer look at the environmental performance two types of hand soap
alternatives – bar soap and liquid soap.
Significant finding from this study:
The ecological intensity of the liquid

larger volumes.
‘Best choice’ of product is largely

TWO
Minimize our impact on the environment through the practices of
restoration, respect, reduction, reuse and recovery or the 5 R’s outlined
by o2 International Network for Sustainable Design.
OUR MISSION – TWO SIMPLE GOALS
R1 – RESTORE
Through collaboration with
supplier, we are dedicated to
restoring the environment
by sourcing products and
ingredients that are
sustainably harvested or
encourage environmental
regeneration
R2 - RESPECT
From the source of our
ingredients to the hands of
our customers and
everyone in-between, we
strive to ensure the well-
being of every person who
touches our products.
R3 – REDUCE
With the cooperation of our
ingredient and brand
suppliers, we aim to
minimize the superfluous
materials that enter our
store so that we can supply
our customers with only
what they use – quality
beauty products.
R4 – REUSE
Along with minimizing,
materials used are
repurposed and recycled
whether through
coordinating with our
suppliers or our customers,
we are dedicated to using
materials to the maximum
of their life.
R5 – RECOVER
For us, Recycling isn’t just
about taking back material
and using it again, it is
about returning material
back to nature. When
disposables are needed,
we source these materials
to be biodegradable.

This client is developing a new product for the medical industry with the goal of alleviating the
difficulty and embarrassment associated with providing a bedpan to a bed ridden patient. The
project was to develop a new product that would allow a bed ridden patient to use the toilet
comfortably, safely and easily while remaining in the hospital bed. Ultimately, this would be
done with minimal or without any assistance of a health care professional or caregiver.
Several concepts were generated and evaluated for feasibility.
Preliminary prototypes were developed and initial mechanism
explored. These devices were used to explore feasibility with
user focus groups and caregivers. The concepts are currently
under review for additional IP and FDA compliance.

DOWNHOLE MEASUREMENTS TOOL
CAPACITIVE SENSOR DESIGN FOR IN-SITU MEASUREMENT
An oilfield technology company that designs electromechanical tools to characterize an oilwell
while drilling. This project was to innovative ways to characterize weight, torque, vibration, shock
and temperature. Sixteen concepts were presented; the top four were investigated. US and
international patents were awarded for these concepts.
The desired measurement is derived by measuring strain in a drilling tool. Historically, load cell
assemblies achieved accuracies of +/-2Klbs with the limitation of gauge fatigue, measurement
drift and frequent re-zeroing a dynamic environment with +20ksi pressures and +400 °F
temperatures.
This effort evaluated non-contact sensors to improve manufacturability, performance and life
compared to current and other concept designs. A capacitive displacement sensor system was
implemented as shown. Testing showed the following significant improvements
in gain, hysteresis, mechanical cross-talk and noise. However, the thermal
cross-talk was difficult to characterize.

CRYOGENIC ELECTROMAGNETIC VALVES DESIGN
Thesis Abstract
A major limitation of Gifford-McMahon, G-M, cryocoolers is the requirement to conduction cool the
refrigeration load. Earlier attempts to use check valves to rectify oscillating pressure in an external
flow loop were unsuccessful. A G-M cryocooler was modified with Boreas style cold
electromagnetic valves to utilize oscillating pressure to drive unidirectional flow. Minimum leakage
and acceptable electrical dissipation even at 4.5 K was achieved. Preliminary analysis indicated
the G-M blow down process could be used to power the flow without degrading cooler capacity.
A paper under the same title was presented at the 11th Annual International Cryocooler Convention
in Keystone Colorado. The paper appeared in the Cryocoolers 11 publication in 2001.
