Description: Green Infrastructure, Waste Water Recycling, and Organic Waste Integrated Treatment System 
The wastewater, as well as organic waste, leave the building heading to the vermifilter where earthworms and beneficial bacteria digest sewage and the residual water. The castings are then pumped to the flat roof where the laminar green roof system promotes evapotranspiration to cool the building as the plant roots symbioses with facultative bacteria to better clean the water. The water then goes to a green wall where more cooling occurs. Residual water can be reused to flush toilets or infiltrate the subsoil already. From a technical perspective, the system is very simple and easy to operate with relatively low cost compared with conventional systems. However, awareness and incentives through national, state, and municipal policy are needed to obtain scaled gains.
Expected outcome: The outcomes of the adoption of this system by communities are less pollution, less energy consumption, less global warming, and greater resilience to energy shortages in the future. It will also enhance social welfare for communities and enhance the visual attractiveness of building façades.

NWPGeographicScope: Global
Indicators of achievement: A system prototype has been implemented and analysis of effluent showed that the system can successfully process organic waste and wastewater for a 15-person building, making it independent from the city sewage infrastructure and organic waste collection as well as cooling down the interior and exterior of the building. Low maintenance and no residual sludge indicate that the system could be applied to large buildings.

Purpose: The objective of this system is to propose a new paradigm for decentralized wastewater and organic waste treatment that could be integrated into the building landscape as green roof and green wall, increasing the green infrastructure in urban areas. This system can be applied to any commercial, residential or industrial building, creating independence from the urban wastewater network and municipal organic waste collection. The crescent adoption of this system can substantially reduce air conditioning energy consumption, treat wastewater, reduce wastewater infrastructure and energy, and avoid waste water plant construction, substantially reducing organic waste transport and waste land contamination. It also reuses wastewater and rain water in green roof and green wall evapotranspiration to reduce the urban heat island effect. This system is especially useful in tropical and sub-tropical areas that have not developed wastewater treatment infrastructure in place. It requires low maintenance and allows for the reuse of water and nutrients reducing pollution of rivers, lakes and ocean. Municipal governments can also benefit from the scaled-up use of this system as there would be reduced need for wastewater infrastructure and organic waste transport. The system uses new vermifilter technology to process organic waste as well wastewater. After filtering the waste, the water goes to the green roof laminar system and then to the green wall or green façade, cooling and refreshing the building by evapotranspiration.
