About this file
The document is a detailed waste composition analysis for Dane County, Wisconsin, based on 20 samples collected to understand the breakdown of materials in the local waste stream. The study categorizes waste into major groups including Paper (20.3%), Plastic (15.3%), Metals (3.3%), Glass (3.0%), Organics (34.0%), Construction & Demolition (6.2%), Problem Materials (3.7%), Other Waste (6.7%), and End of Sample Fines (7.2%), totaling 100% of waste composition.
Key insights from the analysis reveal significant proportions of organic materials (34.0%), with wasted food accounting for 11.9% and food scraps for 8.8%. Paper represents the second-largest category at 20.3%, with mixed paper and compostable paper being notable subcategories. Plastics constitute 15.3% of the waste, with various types of bottles and rigid containers included. The data provides standard deviation and 90% confidence limits for each material type, offering a statistically robust view of Dane County's waste stream composition that could inform recycling, waste management, and circular economy strategies.
