How to become and remain odour compliant in Victoria
Victoria is a beautiful state on the south-east coast of Australia. Home to over six million people and some of the country's most beautiful natural scenery, the garden state places a strong emphasis on environmental protection.
The Environmental Protection Authority of Victoria is responsible for the development of policies and the enforcement of legislation around air, water, and land pollution as well as industrial noise and waste. One of the specific areas governed by the EPA is the control of offensive odours.
To enforce regulation compliance, the Victoria EPA will issue hefty fines for non-compliance. For example, in September 2018 the City of Boroondara was fined $8,000 for odour issues related to landfill gas, and a Brooklyn meat processing company was fined over $7,000 for allowing offensive odours to leave the site. A massive $35,000 fine was also levied against a composting site in the suburbs of Melbourne.
Preventing odours from reaching neighbours is essential in Victoria. So what are some practical ways to approach this problem?
Industries that cause odours
Numerous industries produce waste or use processes or chemicals that generate odours. One of the most commonly recognised odour is hydrogen sulphide - a gas often associated with organic waste sewage and smells like rotten eggs. Other industrial causes include:
- Landfills, organic waste processors, and waste water treatment networks which are all prone to releasing H2S gas.
- Yeast manufacturing creates an offensive odour which can cause problems with nearby residents and businesses.
- Food and dairy processing produces a number of volatile organic compounds that irritate locals.
- Abattoirs and tanneries deal with onsite slaughter and processing of livestock, manure, waste products, and wastewater. All of which carry a distinct scent.
- Meat and livestock facilities primarily deal with manure, which could be spread over a large geographical area.
The list of potential odour sources in various industries is long. Even widely enjoyed smell like coffee roasters, bakeries and powder coaters may require odour control solutions, according to EPA policy.
How to handle odour complaints
Victoria EPA has a recommended flow chart for handling odour complaints from near by residents and avoiding fines. Simply follow these steps:
- Determine if the odour is coming from your site.
- Identify where on your site the odour could be coming from. Check the current status and recent history to see if the odour is present.
- Check and repair preventive measures if you already have an odour control solution in place.
- Do a risk assessment to add to new or existing odour prevention methods that need implementing.
- Reassess and ensure the odour problem has been solved.
Odour control methods
There are four main categories of odour control solutions. The one which is most applicable will depend on the industry and the specific odour problem at hand.
Chemical dosing is designed to reduce the production of H2S gas from sewage, industrial effluent, and wastewater. This solution is ideal for any industry processing organic material that generates wastewater. Different chemicals like magnesium hydroxide, ferrous chloride, and calcium nitrate are available as dosing agents. Seek expert advice to help you make the right selection for your needs.
Carbon filters reduce toxic gases, VOCs, and odours by up to 99%. These systems are used in applications where odour containing vapour streams can be routed directly to the filter. Sewer vents and industrial applications often make use of carbon filters for odour control.
Biofiltration operates similarly to carbon filters, except the filter medium is microbiological rather than activated carbon. Biofilters are good for organic odour sources. Food and dairy processing, abattoirs, and tanneries, meat and livestock, as well as landfills and compost producers all make use of biofilters with the aim of isolating and capturing the offensive vapours.
Misting and vapour systems create a boundary where sources of odour can be isolated and treated. Boundary fence treatment is used to release odour treatment agents directly into the air. As these reactants mix with odours in the air, they neutralise them, preventing offensive odours from reaching neighbours.
Developing an odour management plan
An odour management plan is the first step to identifying odours on your site and getting them under control. It's always better to have a systematic approach to improvement than to try and resolve individual problems in a piecemeal fashion as they emerge.
