Odour Management for Organic Waste Facilities

Odour Management for Organic Waste Facilities

Going beyond the theoretical, this one-day workshop will delve into odour management for each phase of organic residual processors from planning to operation (composting, anaerobic digestion, landfill and transfer stations). Presented by senior odour expert with over 20 years of practice in the assessment, measurement and prevention of odours

Community Odor Monitoring

The objectives of Community Odor Monitoring Projects are to involve the community in assessing odor impacts, determine the odor impacts on nearby residents and provide feedback to operators, stakeholders and community members. A well-executed Community Odor Monitoring Projects helps identify sources of odor pollution and assess the performance of implemented solutions. It also improved factual information and enable proactive response of plant operator to the neighbors’ concerns.

Odor Monitoring for Composting Order of Approval

Lenz Enterprises has an Order of Approval from the Puget Sound Clean Air Agency. This approval required installation of an odor monitoring system that measures and reports results in odor units (OU)/cubic meter. Lenz installed an Odotech monitoring system, which has electronic noses (e-noses) positioned near the odor sources — one located on the back wall of the ASP zones and the other on the northwest corner of the organics receiving building. Sensor data is automatically logged by the Odotech system and Lenz uses this information to develop reports for the agency.

How to Measure Odors

Odors are normally quantified by dynamic dilution olfactometric analysis. Olfactometric analysis consists of determining the olfactory perception threshold of a gaseous sample. The olfactory perception threshold is defined as the number of dilutions at which 50% of a jury perceives the odor while 50% do not. This does not involve the determination of the quality of the odor. By definition, the olfactory perception threshold is equivalent to 1 odor unit per cubic meter of air: "1 o.u./m3". The number of dilutions of the odor sample required to obtain 1 o.u./m3 indicates the odor concentration of the sample in odor units per cubic meter of air [o.u./m3].
