Coral reefs - stunning, critical habitats for an enormous array of prized fish and other species - have survived five major extinction events over the last 250 million years.

Biological treatment, composting, in particular, is a relatively simple, durable and inexpensive alternative for stabilizing and reducing biodegradable waste. Co-composting of different waste sources allows to enhance the compost nutrient value.

Urban water and wastewater management are relatively under-studied subjects in India. The Indian urban space has been understood in an undifferentiated manner, which ignores the specificities deriving from the stage of urban development, the sources of water, as also the diverse nature of aquifers characterizing urban settlements.

The emerging field of sewage chemical-information mining is taking advantage of a readily available yet underappreciated resource: the untreated waste flowing under our feet and the biosolids remaining after treatment. It turns out that sewage and sewage sludge hold a wealth of data on chemical consumption and exposure, and potentially even the health status of whole communities.
