Webinar Floriade Dialogue 11th Edition, Friday 5 February 2021
CET: 10.00-11.30 hours

This Floriade Dialogue edition is all about ‘Analysing and understanding the value of Urban and Regional Waste’. We will discuss the importance of data in Sustainable Resource Management and City Material Flow Mapping. Understanding the City and Regional Material Flows means understanding the value, economic benefits and incentives for growing green cities.

Waste with benefits

As our cities grow and our production and consumption is in full swing, utilising waste will be a key factor for sustainability and even prosperity. It may sound illogical, but we actually are throwing away valuable resources ‘en masse’! Last year the Japanese government recycled gold from over six million devices to help make over 5,000 Olympic medals for the Tokyo Olympic Games. If we recycle aluminium, it will only use 5% of the energy used to make aluminium from new materials and each ton of recycled paper can save 17 mature trees. Bottomline: “waste has an important potential economic and ecological benefit…”

Circular urban metabolism

Knowing waste has a value has political consequences worldwide and requires higher priority through clear objectives. The gradual progression anticipated by the EU means that recycling will grow to at least 65% and landfilling decrease to less than 10% of municipal waste by 2035. In order to set priorities in growth of recycling we need to know which waste to tackle first! To answer this question we need a new urban framework for understanding the main flows (e.g., materials and energy) that enter in city that are used or stored, and then leave the city. This insight is gained via a model that describes and quantifies the main flows and the sum of processes that occur in cities, resulting in growth, production of energy, and elimination of waste called: “circular urban metabolism”.

The bright future of waste

The goal is to encourage urban planners and decision makers to study, design, and manage sustainable cities and their mass flows. This will unite and enforce research fields to change urban planning and design and manage cities’ complex waste flows. This Floriade Dialogue Webinar will discuss the way we will reach objectives on urban waste recycling, decrease landfill and address stakeholders responsibility. The dialogue will focus on urban mass flow analysis, the effect on policy measures and economic instruments that will get waste on a bright and valuable future agenda.
