rban areas concentrate not only economic and social production, but also waste production. Waste that is often addressed at the end of a long chain of actors- manufacturers, retailers, consumers, disposers, municipal councils, collectors, recyclers. And thus waste’s final destination and the impacts of the same are made invisible. The problem of what to do with waste is externalised by actors along the chain of waste production, an externalisation aided by structures that promote it; or that are not present to encourage better waste handling.

Inspired by a semester-long research project on the sources, amounts, destinations and impacts of Wellesley College’s waste, and with memories still fresh of my confusion from all the different categorisations of waste  in the US while studying there, I decided to investigate what role design has in influencing the outcomes of waste handling in public urban spaces. I wanted to know what the qualities of a good trash can design might be, and what cities needed to be doing to get their waste options in line with their waste goals.

I observed various waste management options (reduce, reuse, recycling, garbage, compost) and their uses (or not) in public spaces in New Orleans, USA; São Paulo and Curitiba, Brazil; Cape Town, South Africa and Hà Nội, Vietnam- cities I was in as part of an educational programme. This often meant staring into trash and recycle bins, and standing with a notebook and pen in hand close to others for an hour at a time watching what people did with their waste. I also spoke with city residents and people working in waste management to find out more about the choices individuals and cities made. The insights I gained from both of these inform an analysis of how design can be used to achieve desirable waste management goals including a reduction of waste ending up in landfills; a reduction of emissions such as methane and dioxins; resource recovery and job creation; and internalisation of the impacts of current waste management practices.

I considered elements such as physical shape and size, number, placement, graphics and language employed on observed waste options. I concluded that design, besides being present, needs to be responsive to context and needs, clearly communicate, and effectively share responsibility for waste handling in order to help attain the goals of waste reduction in urban areas. But what exactly does this look like in reality and is there an ideal design for waste management?

Physical Design

Dual compartment bins in park around Hoan Kiem Lake, Hanoi. Green, organics; Yellow, inorganics

Such dual bin structures for organic and inorganic waste, coloured green and orange respectively, were in the park surrounding HoanKiem Lake in HàNội’s French Quarter. The two bins are of the same size. In a public park such as this where people participate in a variety of activities such as walking, jogging, having meals and picture taking, there is potential for a variety of wastes to be generated. The provision of two catch-all options, broadly defined, indicates that this variety of activities, and therefore of waste was taken into consideration.

Different sized bins with 'familia folha' (leaf family) mascot, bus park, Curitiba

At a bus park in Curitiba, where people would be boarding and alighting from journeys, and seats were also provided for the general public, the same consideration for a variety of wastes generated was present. In addition to anticipating a variety of waste, the design also anticipated that recyclable waste would make up the larger proportion of this. Hence the non-recyclables bin was about half the size of the recyclables bin. In both cases, physical design was responding to probable needs by using size and shape elements.
