About this file
The document is a comprehensive waste composition analysis for Dane County, Wisconsin, based on 20 samples collected to characterize the breakdown of waste materials. The study categorizes waste into major segments including Paper (20.3%), Plastic (15.3%), Metals (3.3%), Glass (3.0%), Organics (34.0%), Construction & Demolition (6.2%), Problem Materials (3.7%), and Other Waste (6.7%), totaling 100% of waste composition.
Key insights from the analysis reveal significant proportions of organic waste (34.0%), with wasted food (11.9%) and food scraps (8.8%) being prominent components. Paper waste represents a substantial portion at 20.3%, with mixed paper (4.9%) and compostable paper (7.5%) being notable subcategories. Plastic comprises 15.3% of the waste stream, with various types of plastic containers and films represented. The study provides detailed percentage breakdowns for each waste category, including standard deviation and 90% confidence limits, which can inform waste management strategies, recycling efforts, and resource allocation for Dane County's waste management initiatives.
