What are the biodegradation rates of cedar vs. eucalyptus wood in outdoor trash cans left unused?

When comparing the biodegradation rates of cedar and eucalyptus wood in outdoor trash cans left unused, several factors come into play. Cedar wood, known for its natural resistance to decay, contains thujaplicins and other organic compounds that significantly slow its decomposition process. In outdoor conditions without use, untreated cedar may take 15-20 years to substantially degrade. Eucalyptus wood, while durable due to its high density and natural oils, generally biodegrades faster than cedar when exposed to moisture and microbial activity. Unused eucalyptus trash cans typically show noticeable degradation within 8-12 years in temperate climates. The biodegradation rate varies based on climate conditions, with both woods decomposing faster in humid environments where fungal and bacterial activity is heightened. Cedar's superior decay resistance makes it more suitable for long-term outdoor applications, while eucalyptus offers good durability with slightly faster return to natural cycles. Proper sealing and placement can extend the lifespan of both wood types in outdoor settings.
