Overview

EMASESA, as the public entity responsible for water and waste mater infrastructure and management in Seville, will undertake circular renovation of old water and sewage pipelines by recycling concrete, road surface, filling, and soil. The pilot focuses on water network infrastructures and the materials are concrete pipes, road surface, soil and filling material. 

Implementation

• The CDW quality and technical properties of the dug up pipes in the demonstration sites will be analysed and compared to required specifications
• If it meets the quality standards, the CDW will be used to replace primary raw materials and/or to improve soil quality in nearby municipal sites.
• The piloted material management approach will be incorporated into green procurement criteria that can be used in other similar public works 
• EMASESA will work to engage construction stakeholders to mainstream the use of circular considerations in public contracts, and will also publish a practical guide for quality classification and handling of CDW according to the waste hierarchy.

• Quality assessment for CDW

Overview

Digital tools have been developed to optimise the use of Seville’s five clean points for collection of CDW from citizens and small producers. Data will be shown through a web portal, with one interface for citizens to instruct them to the clean point best suited to receive their CDW, and one interface for city managers to understand the quantity of CDW at each clean point and plan for future scenarios of city growth to open new clean points. 

Implementation

• Data collected on the stocks and flows of CDW through the cities’ clean points will be used to continuously optimise their management.
• The collected CDW will be treated by FERMOVERT if need be, to ensure its safety and quality for further future uses.
• LIPASAM, the waste management company of Seville, plans to analyse the composition of the CDW collected in Clean Points, in order to evaluate the potential uses of the material recovered and be able to take decisions with the aim of recuperating costs for the clean points management and CDW treatment.
• An awareness campaign will aim to introduce these tools to the public and encourage proper handling of CDW, in order to avoid the common practice of illegal dumping of CDW.

Overview

IDENER has developed digital tools to integrate available data on environmental, economic and social development in Seville municipality in order to facilitate data-driven decision-making and better understanding of the impacts of policies and initiatives on citizen wellbeing, and to ensure the city is on the right track towards the sustainable development goals

Implementation

• Citizens will be able to access information about their waste generation, and how city initiatives are impacting a series of sustainability and wellbeing indicators
• Based on the experiences in CityLoops demonstrations and the data visualised through the city simulation platform, best practice guidelines for construction and demolition waste management will be developed
• The guidelines are expected to feed into a new Waste Management Plan for the city of Seville

Overview

A selective bio-waste collection route will be demonstrated within CityLoops in a city neighbourhood by LIPASAM, the municipal waste management company of Seville. This project aims to improve both the quantity and purity of the bio-waste collected by the city

Implementation

• A set of bio-waste collection containers will be installed, for exclusive access to neighbourhood citizens and commercial establishments, with an information and awareness raising campaign to accompany this.
• A software tool designed to optimise the logistics of bio-waste collection is also being developed and will be tested in the demonstration neighbourhood. 
• Alongside the demonstration action a further (mainly digital) awareness raising campaign will be launched across the whole city aimed at encouraging people, mainly large generators such as Horeca bodies (HOtels, REstaurants, and CAtering) to reduce food waste.
• If the demonstration action is successful, recommendations will be developed for upscaling across the city.

Overview

The methane production capacity of the bio-waste collected from demo action 1, will be tested through a process of co-digestion with sewage sludge in a wastewater treatment plant (WWTP). This is being tested as an alternative to the current collection and transportation of bio-waste for composting. 

Implementation

• The aim of this action is to reduce the distance travelled by the bio-waste (and consequent fuel consumption and CO₂ emissions), and increase the energy self-sufficiency of the WWTP
• Following this action, feasibility studies will likely be carried out to evaluate the use of bio-waste, as source of biogas to be used as fuel for the fleet of municipal vehicles, urban buses and heavy-duty vehicles for waste collection, among others
