Summary
Thailand
Area of Science:
- Environmental Science
- Waste Management
- Public Health
Background:
- Thailand faces a significant household hazardous waste (HHW) management crisis.
- Improper disposal of HHW poses risks to environmental and human health.
- Urban and rural areas are both affected by HHW challenges.
Purpose of the Study:
- To characterize and quantify household hazardous waste (HHW) at its source.
- To assess HHW generation across different local administration levels in Nakhon Nayok province, Thailand.
- To inform effective HHW management strategies.
Main Methods:
- Conducted a study on household hazardous waste (HHW) characterization and quantification.
- Analyzed HHW at the source across all local administrations in Nakhon Nayok province.
- Quantified HHW as a percentage of total household waste.
Main Results:
- Household hazardous waste (HHW) constitutes 2.53% of total household waste, approximately 2.90 tons/day.
- Paint products (20.1%), household batteries (17.4%), and unused medicines (14.1%) are major HHW components.
- HHW composition varies by administrative level, with significant contributions from automobile products, paint, and pesticides.
Conclusions:
- Despite its small proportion, HHW poses significant health and environmental risks due to toxic components.
- Effective HHW management, particularly source reduction and separation, is crucial.
- Increased focus on at-source HHW management is recommended for Thailand, even during pandemics.
