The Application of Theory
Integration of scales – mass-produced plus locally  
made parts
An important but little explored aspect of sustainable product design 
is a reassessment of our scales of production so that products can 
be made, repaired and reused within an industrial ecology of cyclic 
resource use at the local or regional level. Where appropriate, products 
and parts could be made using locally available resources, but there 
would remain many components that would be more appropriately 
manufactured in high quantities. For example, light sockets, bulbs 
and electronic parts would be difficult to manufacture at the local 
level and it would be inappropriate to do so. It is important to retain 
standardization of these types of components for safety reasons and 
to ensure compatibility. Sustainable product design must, therefore, 
combine and integrate scales – using locally and regionally produced 
parts from regional materials in combination with mass-produced parts. 
If the mass-produced parts are designed so that they are not specific 
to a particular product, they can be recovered and more easily reused 
in other applications. A standard, mass-produced lamp socket can be 
used in a variety of lighting designs; similarly, a length of threaded rod, 
electrical cable or a keypad has many possible design applications. On 
the other hand, a specialized moulding produced for one particular 
product application might be difficult to reuse. 
The Lumière Floor Lamp, Figure 9.12, is a simple design that illustrates 
this integration of scales. It utilizes a number of off-the-shelf, mass-
produced components, including a lamp socket, a mini fluorescent 
lamp, cable, a floor switch, threaded rod and fasteners, together 
with locally produced and found components – reused hardwood 
components for the cross
-arms and base, a sheet of locally made 
paper as the shade and a large pebble for the base weight. Packaging 
and shipping of components is reduced to a minimum. Fabrication of 
several parts and product assembly is done locally and the basic design 
can be modified and adapted to suit local requirements. In addition, the 
design is such that its construction is explicit and easily comprehended 
– this facilitates repair and disassembly for replacement or recovery 
of parts. Reuse is encouraged by the fact that all mass-produced 
components are standard, off-the-shelf parts. Another design that 
combines a mass-produced part with a locally made base is shown in 
Figure 9.13, G-Clamp Nutcracker.
