Waste Audit Manual

This manual provides a practical, step-by-step methodology for conducting industrial waste audits to support waste minimisation and improved environmental management. It explains the stages of audit planning, pre-assessment, process mapping, material balance analysis, waste and emission identification, evaluation of waste reduction opportunities, economic assessment, implementation of action plans, and performance monitoring. The manual also describes data collection methods, audit organisation, and reporting procedures, and includes detailed industrial case studies from the brewing, leather tanning, and printed circuit board manufacturing sectors to demonstrate the application of waste audit techniques and material balance methods in identifying practical opportunities for reducing waste generation and improving process efficiency.
