The problems we as citizens mostly face is litter and waste in public spaces. This can have a negative impact not only on the perception of our surroundings but on our physical and mental health.  

There is also a deeper issue that needs to be addressed in the near future. Our planet has a limited supply of resources and landfilling and incinerating our waste even if it generates energy is not a sustainable option. We need to focus on recycling and zero waste policies too, as they will dictate the future health of our cities.

We believe in change and our solution focuses on the close connection between citizens and technology. This is why our solution is composed of several parts: a set of sensors on every public bin and a mobile application providing multiple functionalities.

The new sensors paired together with the app will innovate the way waste is managed in the city of Aarhus by improving the way trash levels are monitored, and thus the way bins are emptied, and informing and encouraging more people to recycle and stop littering. 

The data provided by the sensors can lead to the estimation of the most efficient container collection routes in the city. This in turn will increase fuel efficiency for collection services vehicles.  

The application can provide statistical analysis based on weather patterns, crowdedness, days of the week, internet and local municipalities resources, events, and holidays, using the sensors from the trash bins, to predict trash accumulation and establish local waste patterns.

The sensors will be composed of both optical and motion sensors and will make use of the already existing and evolving network of LoRaWAN sensors in Aarhus. 

These aforementioned patterns will provide authorities with relevant data, and citizens with information about pollution rates, places to recycle, and infographics on how to properly recycle and dispose of your litter.

One of the main functionalities of the app is that it can provide and update the locations of existing regular and recycling containers, while also showing the volume levels for the smart bins.

Because one of our other focuses is educating the population about the importance of keeping a clean environment, we can offer citizens recommendations about waste management from both government and scientific sources. This will include advice on reducing waste generation and efficiency in collection and recycling. Non-invasive notifications can remind users about their role during peak hours and before weekend nights. 

Incentives are an important factor in the user experience. We can reward users for continuous use, especially in the future when Pant-like systems can emerge for regular packaging. Incentives could also be offered for the cleanest parts of the city, in order to encourage all neighborhoods to partake in keeping the city clean.

To summarize our idea, we want to use the existing infrastructure in Aarhus, while adding new sensors to the bins, analyze the data in order to improve waste management and collection, and have an app that will both help and encourage users to be more environmentally friendly. In time this can lead to a significant decrease in waste production in public areas and neighborhoods, and will also have a positive impact on recycling practices and resource utilization.
