About the National Environment Agency
Formed on 1 July 2002, the National Environment Agency (NEA) is the leading public organisation responsible for improving and sustaining a clean and green environment in Singapore. The NEA develops and spearheads environmental initiatives and programmes through its partnership with the People, Public and Private sectors. It is committed to motivating every individual to take up environmental ownership and to care for the environment as a way of life.
By protecting Singapore's environment from pollution, maintaining a high level of public health and providing timely meteorological information, the NEA endeavours to ensure sustainable development and a quality living environment for present and future generations.
Innovation Call for Pollution Monitoring Solutions
Emissions from motor vehicles and industries are the two key sources of air pollution in Singapore. As part of NEA’s continued efforts to further improve our air quality, NEA seeks technological solutions for remote real-time monitoring of emissions, in order to assess effectiveness of pollution control measures and implement new control policies/measures.
The two problem statements under this call are:
(A) Remote, real-time and low-cost sensor-based system for the monitoring of nitrogen oxides and particulate matter emissions from diesel vehicles
Diesel vehicles are a significant source of NOx and PM (particulates) emissions into the ambient air. These pollutants have negative impacts on health and environment. The studies have shown that real-world emissions of pollutants, mainly NOx and particulates, from in-use vehicles are much higher than the levels measured during the lab emission tests. Hence, solution for the low-cost, remote and real-time monitoring of NOx and PM emissions is sought to monitor real-world emissions from in-use diesel vehicles and review adequacy of existing policy measures and formulate new controls to further improve air quality.
(B) Odour monitoring and source tracing of odour incidents caused by industries.
Undesirable odours contributes to air quality concerns and affects the quality of living. Due to human’s ability to detect odorants in very small concentrations, otherwise insignificant and unhazardous air pollution sources may give rise to feedback from the public. Investigation of odour nuisance feedback aims to identify the chemicals contributing to the odours and identify the air pollution source(s) causing the odours. There is however a lack of suitable odour detection and analysis instruments for field monitoring. It is also highly challenging to trace the source of the odours from the feedback location which is potentially influenced by multiple emission sources from different types of industries. Hence, this motivates the need to develop a solution capable of continuous monitoring of odours and source tracing of odour incidents.
Interested qualifying parties are invited to submit proposals in response to either or both of the problem statements.
(A) Remote, Real-Time and Low-Cost Sensor-Based System for the Monitoring of Nitrogen Oxides (NOx) and Particulate Matter (PM) Emissions from Diesel Vehicles
NEA seeks solutions for the low-cost, remote and real-time monitoring of NOx and PM emissions from diesel vehicles on the road.
The requirements for the solution are:
(B) Odour Monitoring and Source Tracing of Odour Incidents Caused by Industries
NEA seeks scalable solutions for detecting and monitoring odours, characterising the chemicals contributing to the odours, and identifying the sources of the odours. A given solution shall be applicable for odours arising from different industrial types. The sensing devices shall be in-situ devices which can be used in a network for the near-real-time monitoring of odour source and receptor areas. The solution may also include sensing devices that can be handheld by NEA officers or mounted on vehicles for field investigation. The solution shall transmit in near-real-time the odour concentration and alert NEA of a potential odour incident, whenever the measurement exceeds a pre-set threshold. It shall also be able to identify the chemical components (which are likely to be present in very low concentrations) of the odours, as well as enable officers to trace the odours to its source.
The call is targeted at Singapore-registered companies, as well as institutes of higher learning and research institutes based in Singapore.
A technical briefing will be held on 19 Oct 2017 (Thursday), from 2.30 p.m. – 4.00 p.m. Interested parties can register for the briefing here.
