The bins will be used to manage organic waste generated by the hospital's kitchen. The initiative is implemented by Swisscontact within the Zero Waste project financed by the Swedish International Development Agency (Sida). It has the support of the local city government, the municipality of La Paz and the Departmental Health Service (Sedes).
The compost bins of the company Ecofractal hold 700 litres and will transform kitchen waste (including citrus fruits, processed food and eggshells) into biofertilised soil by means of micro-organism accelerators. This technique will generate biofertiliser to be harvested in just one month. Also, the creation of harmful CO2 and leachates – contaminated water – will be avoided since, thanks to this process, the food remains do not rot, nor do they generate bad smells. Therefore, this system does not cause the presence of potential carriers of disease such as flies or mice.
The Hospital de Clínicas has a waste treatment plant that transforms pathogenic waste which could cause diseases into normal waste. In this way, the waste treatment initiative contributes to improving the integrated waste management in this hospital, says Marco Martínez, Director of prevention and Environmental Control of the municipal secretary of Environmental Management and Renewable Energies.
The municipality of La Paz is currently working on training in composting, vegetable gardens, and in schools. In the latter training, kids learn to separate organic and inorganic solid waste through the educational programmes "Sustainable Schools" and "Barrios de Verdad de Mil Colores".
It is estimates that the compost bins will produce around 230 kilograms of biofertiliser every month:
