While environmental impact is not an inherent aspect of Lean methodology, implementing Lean best practices can effectively contribute to “greening” an organization by reducing environmental waste.

The U.S. Environmental Protection Agency notes that environmental benefits often occur as a byproduct of efforts to minimize or eliminate waste in production facilities. The following five R’s can serve as guidelines for developing a Lean, green enterprise, similar to the well-known three R’s in environmental initiatives.

Recover

In a manufacturing setting, examine processes to identify opportunities for recovering and reusing scrap and waste. This principle can also apply on an individual level, such as utilizing unwanted printouts as scratch paper. Additionally, energy recovery is important; some organizations have successfully converted steam output from machines into electrical power.

Recycle

This concept is widely recognized. After an item has served its purpose, consider if it can be repurposed. At a minimum, participate in local recycling programs.

Redesign

Evaluate whether products and processes can be engineered to consume less energy, last longer, require less maintenance, and be more environmentally friendly throughout their lifecycle.

Reduce

Focusing on minimizing the energy and materials used in production is crucial for any manufacturing organization. Additionally, organizations should assess ways to decrease the resources consumed by a product during its lifetime and the materials needed for disposal.

Remanufacture

Increasingly, businesses are creating new products from old ones. This may involve utilizing still-functioning parts from outdated machines to assemble new equipment or breaking down products to generate entirely new items.
