What a resource-efficiency assessment looks at
Programmes like SAVE send engineers into factories to find where energy, water and materials are wasted, then help the factory fix the biggest items first.
Typical areas
| Area | Typical measures |
|---|---|
| Steam and heat | Recover waste heat from engines and boilers, return condensate, insulate pipes |
| Water | Reuse rinse water, meter each process, cut water per kilogram of fabric |
| Electricity | Efficient motors and lighting, compressed-air leak repair |
| Chemicals | Restricted substances lists and better dosing |
| People | Training staff to keep the savings going |
Published examples from PUMA's supply chain
| Factory | Measure | Result |
|---|---|---|
| Shenzhou International, Ningbo (China) | Six-step environmental improvement plan | 7.7% less energy, about 10% less CO2, 13% less water |
| Square Fashion Limited (Bangladesh) | Waste-heat recovery boiler (5.7 tonnes of steam per hour) on gas-engine exhaust | More than 2 million m³ of natural gas and 4,354 tonnes CO2e saved per year |
These later results come from PUMA's own reporting on supplier programmes such as Clean by Design (with the Apparel Impact Institute in China) and the IFC-led Partnership for Cleaner Textiles in Bangladesh, which continued the kind of work SAVE started.
