INGENIEUR Sustainable Product Design By Ir. Dr Oh Seong Por, Director Samsung SDI Energy Malaysia Sdn Bhd I n the recent century, human activities which involve mass production of products, high consumption of energy and other resources with the intention to bring betterment to mankind have unprecedentedly changed the ecosystem. It is an undeniable fact that every product manufactured has an impact on the environment although the product may provide convenience to mankind. The impact may be big or small, immediate or after lapse of time. Sometimes the impact can only be understood over some period of application. A good example is the plastic bag. When it was first introduced, consumers found it very useful and a convenient way to carry materials even till today. However recently, it has been established that disposed plastic bags contribute contamination which is harmful to the environment and living creatures, triggering a ban or reduction in the usage of plastic bags in many places. Traditionally many environmental problems caused by products have been addressed by the end-pipeline strategies. These business strategies are normally to produce fast and sell many as long as there is demand and find ways later to handle the waste. Even if product usage may affect the environment, it is normally sacrificed for function and profit. In the long term, this frequently turns out to be inefficient since the strategy mostly provides a temporary remedy once the product has been created and not a long-term solution to the issue. This has decreased product sustainability, and if left unchecked, may endanger the ecosystem. The product impact can be controlled more effectively at the design stage. This brings about the importance of sustainable product design, which product developers or manufacturers should apply. As said by Brundtland (1987), “Humanity has the ability to make development sustainable — to ensure that it meets the needs of the present without compromising the ability of the future generations to meet their own needs.” 6 56 VOL VOL 79 55 JULY-SEPTEMBER JUNE 2013 2019 What is Sustainable Product Design? Sustainable Product Design is a product design approach to fulfil needs and acquire reasonable profit to maintain business, with greater emphasis on preventing or minimising impact to the planet through:- i. Conserving energy and water as well as protecting air quality ii. Optimising material usage with no over consumption and no waste iii. Selecting materials that are recyclable and non-hazardous. iv. Protecting a supply chain that is renewable and able to sustain resources. The design should be able to address the environmental impacts of a product throughout the complete life-cycle without unduly sacrificing intended requirements such as function and quality. This definition is best illustrated in pictorial form in Figure 1. What is Sustainable Product Life-Cycle? Sustainable Product Life-Cycle is a process sequence of product development starting from identifying need (or problem) to creating solution, translating solution into design, producing products and distributing to buyers with consideration for product disposal function. It covers the entire cycle, managing product from creation for use until beyond usage. In short, it is the management of waste and impact to the environment along the entire flow, from cradle to grave as demonstrated in Figure 2. The disposal function is integrated in the product design to ensure that at the end of the product cycle and when it is scrap, there is no harmful effect to the environment. Some of the common product disposal functions are:
