Prevention and Collection

Prevention and Collection

The circular transition starts with waste prevention, while separate collection of bio-waste requires good publicity and social acceptance. That is why it must be supported by awareness-raising campaigns targeting households and other producers, such as hotels and restaurants and green spaces managers, explaining why and how to cut down the amount of waste generated and how to sort it properly. Collection in itself is the second step. It covers the set up of a separate collection system, which includes a number of technological, organizational, regulatory as well as financial choices, depending on the local context. Initiatives like community or garden composting - the best options for closing the loop in low-density areas - are also part of this second step. A proper source collection keeps the level of impurity and contamination down as far as possible and enables the use of bio-waste as a secondary raw material. Lastly, further cleaning and sorting is required in order to achieve a high degree of purity, an absolute necessity for any valorisation option

Food demand management model

In the City of Porto, the social economy sector and the tourism sector are major producers of avoidable food waste. To provide them with better tools to reduce food waste, this model has been developed to predict food waste in the social economy and tourism sectors. The model is based on historical data on food served and provides information on expected food demand depending on a set of explanatory variables, namely the menu offered, day of the week, and others. The use of the tool will help stakeholders...read more

Smart collection system tool

The City of Porto seeks to improve its waste collection practices to separate bio-waste more effectively. To do so, it will implement a Smart Collection System tool based on a mathematical model that will integrate data from the new installed set of smart sensor containers with the transportation trucks. With this technology it will be possible to identify and locate every container. The data collected will be integrated into an Urban Services Platform. The system collects information on the quantity of waste collected, together with data on usage patterns...read more

OMSW flow optimisation tool

This software tool for municipalities can be used to model possible scenarios for separate collection of biowaste, considering the data on biowaste material flows, to develop the most optimal collection route. Factors such as type, origin and volume of the material, CO2 emissions and loading of the waste trucks, and distance travelled are optimised to plan in a way that minimises negative environmental impact and maximises logistic efficiency of the collection. Data-driven planning decisions can support...read more

Innovative sorting and treatment methods

In preparation of pilot demonstration actions for the innovative reuse of biowaste from public spaces, the City of Apeldoorn seeks to develop sorting and treating methods that maximise valorisation options. The report describes different sorting and treating methods which can be applied to make biowaste from public spaces suitable as feedstock for the production of bio-based products, or as a first step, to show the potential of the biowaste to interested businesses that are currently using biomass from other sources.

Finnish bio-waste collection and treatment systems

This report is a preparatory analysis of the current waste collection and treatment system in biowaste in Finland and more concretely in Mikkeli, with the aim to improve the collection and sorting of biowaste and to develop viable business models using the waste. It lists volumes of both municipal solid waste and high quality biowaste collected. Based on this the report lists potential business cases for the reuse, recycling and valorisation of biowaste, which will be further developed during the demonstration phase of the project.

Bio-waste collection and sorting processes

The City of Mikkeli seeks to reduce the amount of quality biowaste in their municipal solid waste, which is not reused or recovered currently, and increase the volumes of quality organic waste collected separately. The implementation plan describes how municipal solid waste composition will be studied and collection and sorting processes will be developed during the demonstration phase. The report also includes results of first initial situation municipal solid waste composition study, in terms of mass and volume distribution of different types of materials (glass, plastics, biowaste, paper, wood, etc.).

Diagnosis and characterisation of OMSW

The City of Seville aims to divert as much waste from landfill as possible and instead use the biowaste fractions of municipal solid waste (OMSW) for higher value purposes. The diagnosis and characterisation of the current situation of the flow of organic matter (biowaste + organic matter collected is still mixed with the rest fraction), responds to the need to establish a starting point to plan and apply a strategy that allows to achieve the European targets for recuperation, recycling and landfilling. The report presents a diagnosis of the quantity, quality, flows, legal aspects, and current plant treatment of OMSW.
