Study Notes

Remanufacturing and Recycling Processes

Remanufactured products are reassembled on an assembly line using recovered and new parts.
Recycling involves disassembly to reclaim useful material streams and increase material value by removing contaminants.
Manual disassembly is primarily used for separating components.
Recycling without disassembly uses shredding to reduce material size for easier sorting based on properties like magnetism and density.
Disposal methods include landfilling and incineration, with varying energy recovery outcomes.

Design for Environment (DfE) Guidelines

Simplify design by minimizing material usage.
Maximize functionality of single parts without compromising performance.
Avoid toxic materials and heavy metals to prevent contamination.
Design products with multiple uses to enhance intrinsic value, such as packaging that also serves as storage.
Ensure compatibility of materials to ease recycling and explore using recycled materials in new products.

Corporate Examples of Sustainable Practices

Samsung Remanufactured Mobile Phones:
- Utilizes biopolymer casings and recycled paper packaging with soy-based ink.
- Features an online instruction manual and Energy Star rated charger.
Ford Smart Gauge with EcoGuide:
- Instrument cluster in hybrid vehicles to improve fuel economy through driver feedback.
- Developed collaboratively by SmartDesign, IDEO, and Ford.
Puma's Clever Little Bag:
- Designed by Yves Béhar, reducing cardboard use by 65%.
- Eliminates laminated printing and tissue paper to decrease shipping weight and space.
- Replaces polyethylene bags with a reusable bag made from recycled PET.

Fundamental DfE Principles

Design for continual recycling of industrial materials without performance loss.
Create products from natural materials that can fully return to ecological cycles.
Avoid producing toxic materials that cannot be processed safely.
Utilize clean, renewable energy sources, steering away from fossil fuels.

Green Design Awareness

Acknowledge the challenges and responsibilities of adopting green design.
Eliminate toxic wastes, heavy metals, and radiation—elements not suited for the biosphere's cycles.

Integrated Product Development Process

Planning for DfE includes setting agendas and identifying environmental impacts.
The development phases include concept formulation, system-level design, detail design, testing, and impact assessment.
Continuous improvement of DfE processes, integrating guidelines at each design phase including material selection and environmental impact evaluation.

DfE and Material Guidelines

Avoid combining incompatible materials for recycling and label all components.
Facilitate easy disassembly for recycling streams, eliminate surface treatments, and reduce packaging size and weight.
Promote the use of recycled, recyclable, and natural materials for sustainability.

Herman Miller’s Environmental Goals

Aim for zero landfill and zero hazardous waste generation by the year 2020.
