Functions help you to understand what the products can do for you and which ones will help you achieve your goals.
Each solution has at least one mandatory function, which is needed to achieve the basic purpose of the solution, and several additional functions, which are features that can be added to provide additional benefits.
Average Implementation Time: less than 6 months
Sorting waste at the source can be done in different ways: Single or multi-stream. In the single stream version, people dispose recyclable materials in one commingled container, while, in a multi-stream system they have to sort them into two or more bins. According to Lakhan (2015), the single stream system has lower costs of collection, however, the value of the material collected is higher and processing costs are lower in multi-stream systems. As the graphic below shows, the revenue is higher implementing a multi-stream system.
(Lakhan, 2015) Based on data from 223 municipalities from Ontario (Canada) on a period of ten years.
Pricing: Example Pay As You Throw
A common regulation to reduce waste generation and increase recyclables is the called Pay As You Throw system (PAYT). In this scheme, households pay a fee which varies according to the amount of waste they generate. PAYT systems consist of a fixed fee or a tax and a variable element that can depend on "container sizes, the number of sacks, frequency of collection, or the weight collected" (Seyring et al., 2015: 15).
Example of PAYT System in the Veneto Region, Italy:
Example: Parma (Italy)
The city of Parma implemented a new waste management system in 2014, which included a Zero Waste strategy, door-to-door collection, and the introduction of the bio-waste collection. The table shows how the changes made by the city reduced the costs of waste management, which included a decrease of treatment costs for residual waste (due to less generation) and an increase of the income from recycling (as there were more materials and less contaminated). In addition, more jobs were created with the introduction of this system (Rosa, 2016).
Governments are setting recycling targets to increase the amount of waste recovered. In this context, the most progressive initiative is the Zero Waste strategy, whose aim is to recover and reuse all materials avoiding incineration or landfill burying. Cities in Italy (Capannori, Priula, Treviso, Parma), Spain (Argentona, Gipuzkoa), Slovenia (Ljubljana, Vrhnika) and France (Roubaix) have already started to implement Zero Waste policies (Zero Waste Europe, 2017).
Circular Economy - European Union
In 2015, the European Commission adopted the Circular Economy Package, which aim is to reduce resource consumption through better design and to increase reuse and recycling. This package includes legislative proposals on waste with new targets, action on food waste, a finance support platform, and some other regulations (European Commission, 2017).
