Odour management
ARE DEALING WITH NEW CHALLENGES TO OPERATE IN RESIDENTIAL AREAS AS LAND CONFLICTS ARISE Alex Zamudio, Environmental Intelligence Advisor at Envirosuite
Odour complaints arise from the community
How to (re)build trust within the community
Odour impacts livability. It’s the reason for a large number of complaints made to environmental authorities and in communities, with landfills often listed as the top source. Operators with odour issues generate hundreds of complaints a month. These complaints are often supported by a range of external data, from odour diaries and sniff tests to formal air quality monitoring systems set up by investigators. Communities are increasingly impatient about slow and indecisive responses to odour complaints, so it is more important than ever that operators can minimise uncertainty, and reduce the time between a problem occurring and a solution being actioned. For operators, odour management is a complex and increasingly technology-driven process. Outside factors such as meteorological conditions play a part in management approaches and need to be modelled with internal data to make abatement and control measures effective.
As cities sprawl and communities come into closer proximity with waste sites, sustainable operations have never been more critical. Sustainable landfill operations stand on three pillars: 1. Compliance 2. Optimisation 3. Community engagement Communities are redefining their relationship with waste management sites where odour emissions and air quality impacts due to uninformed operational decisions can lead to compliance breaches. Communities, regulators and industry need to be able to trust that one another are doing the best they can for the benefit and in the best interests of everybody. That requires an open conversation and an end to negative actions. Communities lose faith in operators that are perceived to care only about money, and not about community safety or environmental concerns. Nowadays, residents contact landfill sites directly as they can easily find information of rankings and reviews on the internet. Communities now have a voice, an open opportunity to engage with a waste facility operator and the ability to suggest actions or influence operations, so they are more likely to accept the facility’s ongoing presence. They are also less likely to lodge complaints with authorities, since they can be confident of gaining a direct audience with the operator, with a high likelihood of open dialogue and positive action or redress.
New challenges in waste management as suburbia sprawls New set of challenges driving unprecedented change in the waste management sector include: • Residential populations are brought into closer proximity to previously isolated waste and industrial facilities. • Landfill site operators with legacy facilities permits are under community pressure to modernise to meet quality-of-life expectations. • External researchers are pouring pressure by using GIS, census, and satellite data to assess the suitability of locations for solid waste management. • Communities concern more on air quality issues caused by waste management centres and industrial sites.

The power of environmental intelligence in waste management Over the past five years we’ve seen a significant change in the technologies available for odour detection. Only a decade ago, odour detection and management required specialist precise equipment.
