Waste management solution for a zero waste office

Solution context

To tackle the Waste problem in Office buildings. Through our research we found out that there are enermous costs and CO2 emissions associated to the landfill waste (Restmüll) generated in the office buildings. According to the information provided by an office building operator and real estate developer, for an example 12000 m2office building, the disposal costs of landfill waste is 50,000€ annually. In addition to tones of CO2 emissions associated with the transport distances of the waste from the building to the treatment destination. The estimated transport distance per ton is 45km in Germany.

Solution description

Coming from the above mentioned situation, Dispo is the idea of a technology that could reduce the volume of the already generated waste down to only 10% of the original volume. As result, it will reduce the number of visits of the waste transport vehicles and aconsequently reduce the service fees and the CO2 emissions associated with the process.
Such technology already exist in the markets at bigger sizes for the waste to energy power plants, as it improves the calorific properties of waste based fuels. But till now does not exist for Kitchen or building sizes . 
Dispo will be designed in different sizes 1- Kitchen size that could treat 5 Kg/day of house/office use. 2- Building integrated size that could treat up to 1 tonn per day.
