Waste Reduction vs Material Cost
Prevent waste through dimensional coordination and prefabrication at design stage rather than managing disposal after the fact.

Business Context
Reducing construction waste can require more accurate ordering, reusable packaging, prefabrication, material separation, or alternative products. Some waste-reduction measures appear to increase purchasing or handling costs compared with conventional procurement and disposal practices.
Real Estate & Construction TRIZ Resolution
Waste should be prevented before it becomes a disposal problem. Dimensional coordination, optimized ordering, prefabrication, reusable temporary materials, supplier take-back arrangements, and standardized components can reduce both purchased material quantities and waste-management requirements.
Applicable TRIZ Principles
Principle 2 – Taking Out eliminates unnecessary material before procurement.
Principle 10 – Prior Action designs dimensions and quantities to prevent predictable waste.
Principle 34 – Discarding and Recovering returns reusable or recyclable materials to productive use.
Expected Outcome
Reduced construction waste
Lower material consumption
Controlled procurement cost
Lower disposal requirements
Decision Indicators
Early indicators include:
Waste reduction focuses mainly on recycling after waste is generated.
Large quantities of unused material remain after construction.
Standard dimensions are poorly coordinated with purchased products.
Disposal remains cheaper than recovery because materials are mixed.
Waste-management costs rise without reducing material purchasing.
