HOW SHOULD WE THINK? Lee Woodman CCDN 271
Tutor: Kath Foster
“We cannot solve our problems with the same thinking we used when we created them” Albert Einstein.
This earth we all live on has finite resources, and as we are all only too well aware we are using those resources at an alarming rate. The industrialization of the modern age has seen an exponential rise in consumption of new, better, faster products, food, services and lifestyles. Our mastery and consequent dependence on technology has become necessary to maintaining this consumption. My inquiry will look at the most basic assumption behind these phenomena; can we rely on technology to reverse this downward spiral into oblivion of our species? Or, should we stop, and consider the method of thought needed to extricate ourselves from this dilemma? This essay will explore different modes of thought that might help us to reverse this trend and attempt to compare the common elements running through them to give the reader some direction. It should be mentioned at this point that I want to avoid any hollow rhetoric about the environment that saturates our vision at the present. We are in danger of becoming sensitized to the ‘greenwashing’ (put forward by the product industry predominantly) in order to only profit further from the environment by appearing to be concerned about it. Industry globally is growing at tremendous rates, which has implications in all directions. From the start of human history to the year 1900 the world produced six billion dollars of output, now the worldwide economy grows by that amount every two years.1 Technology promised us a lighter, faster way of doing things, but as John Thackara explains in his book In the Bubble, ‘speed’ costs us greatly and we are also much heavier than ever before.2For example, we print much more paper than ever before, even though email and electronic 1 2

transactions promised us an end to the paper trail. Many electronic devices are disposed of after a few years or even months, and computers are one of the most wasteful devices to manufacture. The amount of waste matter generated in the production of one laptop is four thousand times greater in weight than the object itself. And it takes between fifteen and nineteen tons of energy and material to produce one desktop computer. 3 It requires 1.7kg of high grade materials to produce a single 32mb memory chip,4 and these chips are being manufactured at ever increasing rates. 5We only need to think of the consumption of these products in our own individual circle to understand this problem is vast in its scale. ‘Lightness’ is the first term I want to address in context to the amount of resources we all use and discard in first world countries. Thackara points out one solution especially when it comes to products or tools and that is to ‘use, not own’.6 By using without buying we are purchasing a service, not the product. One example he gives is power tools as the average consumer power tool is used for ten minutes in its entire life. 7 Given that it takes hundreds of times its own weight to manufacture, it makes no sense to own something like this.8 All we need is to be able to hire one when we need it. A service based industry would lighten our footprint argues Thackara and writes; “focus on services, not on things, and refrain from flooding the world with pointless devices”. ‘Speed’ is another term that demands attention in technological advances and I believe it is an important subject in context to our modern life and the environment. No doubt most of us have heard of the emerging trends that buck the ‘fast’ slogan; slow design, slow food, and slow cities even. It’s not just the speed argues Thackara; it’s the continual acceleration that is unsustainable.9 As much as we like to arrive at our destination as quickly as 3

possible, our speed addiction is not cheap. For example, the average car uses five litres of fuel at eighty kilometres per hour, but needs four times that amount to go only twice as fast.

quotes an environmentalist named
Wolfgang Sachs saying; “the more speed outdoes natural time scales, the more environmental resources have to be extended. Gains in eco-efficiency will never cancel out the basic law which governs the physics of speed”. 11 Our lives are lived at an ever increasing pace, which seems to have the effect of less time not more. Consequently our quality of life suffers and this has implications on many areas not the least of which is our health. While this topic is quite distant from design and designers, it is useful to understand overarching drawbacks that have crept in to modern life without being foreseen. With that in mind it is time to return to practical ideas and solutions to some of the issues raised earlier regarding product manufacturing processes. An Example in thinking different about our predicament is put forward in a book entitled Cradle to Cradle. This book is authored by William (Bill) McDonough, an architect with passion for designing with intention, who in 1996 received the Presidential award for sustainable development, (the highest environmental honour given by the United States), and Michael Braungart; a chemist and the founder of the Environmental Protection Encouragement Agency (EPEA) in Hamburg Germany. 12 Together these two formed a company advising clients on sustainable practices and systems. It is the knowledge and ideas put forward in this book that I will use as examples of how to think about today’s manufacture and design. Cradle to Cradle suggests a system that is a closed loop; it has no waste and can re-use any raw materials involved, and furthermore proposes a concept to produce the energy needed in that process. The thought of ‘no waste’ is foreign to most of us, we consume and throw away vast quantities of organic matter (food), packaging and as mentioned earlier, hardware (TV’s, computers, electronics etc) that mostly end up in landfill somewhere. This is a cradle to grave model and is a one-way traffic mentality where all our waste 10
Thackara, p. 31 ibid, p. 31 12 William McDonough, Michael Braungart, (2002), Cradle to Cradle: Remaking the way we make things, New York: North Point press. 11
goes away. The truth, the authors point out, is that there really is no ‘away’. Waste goes somewhere and stays there, to decompose or not, and as such is lost forever in this grave. Raw materials fall into two categories; Biological materials and technical materials (metals used in industry). Biological materials are literally food for the planet; they are nutrients that are supposed to be returned to the biological cycle to be consumed by microorganisms and other animals.13 This replenishes the earth’s system and helps retain the cyclic nutrient flow needed for healthy biodiversity. Packaging for example (which makes up about half of all solid waste) could be designed to compost down and return to the earth as nutrients. As the book points out, “there is no need for shampoo bottles, toothpaste tubes, yogurt and ice cream containers to last decades (or centuries) longer than the product that came inside them”. 14 It makes no sense to landfill this material. Imagine being able to throw this type of waste on the garden, knowing you are helping to return biological nutrients to the earth? Technical materials are valuable metals which require damaging and costly processes to extract from the earth’s crust. As mentioned, these metals then get used to produce vast quantities of appliances, devices and automobiles. Again a lot of these products end up in landfill. They are not designed to be repaired and reused once broken and are even designed in most cases to last only a certain time, in industrial terms this is called ‘planned obsolescence’. 15 Once these metals are landfilled they are lost forever to us, unless we dig them out again. (This may not be such a bizarre thought in the future!) Well, you might say, what about recycling? Today we recycle as much as possible and that is good news but there are some significant problems to understand. As Cradle to Cradle points out, recycling is sometimes more harmful to the environment than we would have considered, for two reasons at least. Firstly, most products that get recycled were not designed to be recycled; they must be wrestled into their new form with new chemical additives and more energy and waste to achieve a result. Most plastics 13
Thackara, p.105 ibid, p. 105 15 ibid, p. 98 14
become less usable when recycled. When melted down and combined, the polymers within the plastic shorten which reduces the flexibility and clarity of the plastic. This reduces the use of the product and can result in a more toxic material due to more additives needed for countering this. 16 This is what McDonough and Braungart call downcycling rather than recycling. As they point out, the material is still destined for landfill; it is only stalled by a life-cycle or two on the way. 17 This ‘downcycling’ problem applies to many products that are commonly recycled such as paper and aluminium cans. Secondly, precious metals are mostly lost when recycled as they are melted down along with all the other materials to produce an inferior downgraded material not usable again for its original purpose.18 For example, automobiles when crushed down and recycled lose the high-carbon, high tensile steel and copper used in the original process.19 The metal is melted down along with the paint and plastic coatings on the body which produces an inferior quality steel. New high-quality steel can be added to strengthen the material but it will never be used to make cars again. Meanwhile we have permanently lost the precious metals such as copper, manganese and chromium that would be otherwise useful in their unmixed original state.20 Cradle to Cradle suggests an alternative idea to reverse this loss of valuable technical nutrients which begins with manufacturers producing items with the explicit intention of retaining those specific materials. This requires the designer to design this into the process at the beginning, not trying to squeeze a product into this form after production. Furthermore, these products could then be considered more of a ‘service’ rather than ‘owned’ by consumers. For example, cars, televisions, carpets, computers and refrigerators; all product that use valuable technical nutrients, could be considered a ‘service’ to be used.21 When the time comes to replace or upgrade the product the company responsible would supply a new model for use and retrieve the old product for breaking down and recover the raw materials. The consumer could use the 16

product as long as needed and upgrade as often as they desired. 22 Just as the biological cycle returns its nutrients to the earth, so too the industrial cycle can return its nutrients to the manufacturer in a closed loop scenario where there is ultimately no waste. It is the fundamental idea in this book that it is important for everyone involved in the process to be better off, both the consumer and the manufacturer. Contrary to popular mindset good environmental practice can be better for industry as well. The authors of Cradle to Cradle also envisage manufacturing buildings and processes to create energy and nutrients, much like natural processes. The analogy provided here is a cherry tree, which produces an abundance of blossom, much more than is needed for its own growth and reproduction. Only a very small percentage of blossoms that falls to the ground ever grow to be another cherry tree. But this excess is not ‘waste’ as it falls to the ground to decompose and in doing so nourishes and replenishes the soil and microorganisms around it. Nature works on abundance and excess and most importantly interdependence. 23 The cherry tree helps all the area around it and contributes to the biological cycle with its abundance, and this idea can be applied to our own manufacturing processes. Industrial processes at present place emphasis on fewer emissions, less toxic waste, and less use of precious materials. What if these processes actually gave back to nature as well as taking from it? If we can build factories whose product and by-product replenish and nourish the natural biological cycle and re-use technical nutrients, we could encourage industry and economic growth. 24 Rather than working on a model of ‘guilt’ and ‘reduction’ and ‘less’, we can take our cue from nature and produce more and celebrate short product life spans and encourage consumption. 25

In conclusion, our current processes and habits are working against nature not with it. We have been ushered down a path that no one planned or designed and it is getting uncomfortable. However, there are ways out that do not rely on constraint, regulation and suffocation of industry. We need to think differently about processes and products by acknowledging natural cycles of nutrients. As designers we need to incorporate these ideas at the initial design stage to avoid downcycling. Imagine celebrating growth and consumption knowing that in doing so we were feeding our environment and maintaining valuable technical nutrients? If we aspire to design services and clever processes rather than products; and celebrate life with a slower less weighty existence we will be doing more than just living ‘sustainably’, we would be thriving!
