The United Nations estimates that the number of megacities with a population of more than 10 million will triple from 20 in 2003 to 61 in 2015. It is estimated that more than nine tenths of urban growth will occur in developing nations, with four fifths of urban growth occurring in Asia and Africa.

BioCycling GmbHSince 2006, it is forbidden in the European Union to process leftovers from restaurants, hospitals, canteens and food distribution chains to animal feed. BioCycling, an enterprise owned by Veolia Environment, ensures the disposal and recycling of organic waste for the production of biogas, biodiesel and fertilizers. The biogas and biodiesel produced by BioCycling are used for the production of electricity and heating energy. The fertilizers are used in agriculture.

How does it work?

BioCycling offers services for the clean collection and disposal of food waste in restaurants, schools, hospitals, distribution chains and so on. It provides airtight containers that are regularly collected to be brought to the biogas plant in Stellinger Moor in Hamburg, Germany. In the first stage, the organic waste is reduced in small pieces, packaging and other artificial materials are removed and it is heated up to 70 degrees Celsius for one hour to be sanitized. The waste is then ready to be put in a large fermentation container where the production of biogas will take up to four weeks. With a proportion of 65% of methane the produced biogas is very energy-rich. In the attendant block heat and power plant the biogas is burnt for the production of electricity and heating energy. This CO² neutral energy is directly introduced in the Hamburg electricity and distant heating distribution network. The remaining organic waste is used as fertilizer in agriculture. Out of around 20,000 tons food waste per year, the bio plant produces clean electricity and heating energy that are sufficient to cover the needs of 2,500 households.
