Problem
Gases released from landfills or dumpyards such as H2S, NH3, TVOCs, CH4, CO, etc. are hazardous to human health. They may affect the nervous system and cause irritation to our sensory systems. In addition to the adverse health effects, these gases also cause inconvenience to the nearby locality due to their foul smell. These gases need to be monitored to inhibit their diffusion in residential areas. Reak-time monitoring is necessary for taking precautionary steps against the uncontrolled spread of odour due to dynamic weather conditions.

Concept
Neighbourhoods near landfills find it difficult to cope with the odour caused by waste dumping. A system is needed to bring the foul smell within controlled limits to overcome the nuisance. Data-driven odour analysis is possible by installing real-time odour monitoring systems in and around a landfill. With the help of meteorological data, landfill’s odour nuisance in the neighbourhood can be estimated by applying relevant predictive analytics. This helps to take preventive steps by initiating odour suppression on priority.

Target Parameters
Hydrogen Sulfide (H2S)
Ammonia (NH3)
Total Volatile Organic Compounds (TVOC)
Methane (CH4)
Methyl Mercaptan
Wind Speed & Direction

Proposed Solution
Oizom Odosense, installed around a Municipal Solid Waste (MSW) landfill, dumpyards and Waste-to-energy (WtE) plants monitors odour diffusion in real-time. Odour sources are predicted through composition analysis by monitoring gaseous concentrations. Using Odosense and meteorological data, Oizom cloud application is able to perform odour impact analysis by odour plume dispersion modelling. By setting a relevant Odour Index, Oizom makes the data actionable by triggering smart-notifications. It also predicts odour emission hot-spots using reverse modelling capabilities. The solution helps in automating/initiating odour neutralizers at the targeted site to seize odourful gas emission, thus mitigating the odour nuisance.

Impact
By implementing this solution, efficient and timely odour-treatment is possible which drastically reduces problem-to-solution time. Odour dispersion modelling helps in predicting the impact on the neighbourhood and take necessary actions. Odour analysis and hot-spot prediction lead to a better Solid Waste Management (SWM).
