The Lean and Environment Toolkit offers practical strategies and techniques to Lean implementers about how to improve Lean results—waste elimination, quality enhancement, and delivery of value to customers—while achieving environmental performance goals. The toolkit also provides tools to help your organization get better environmental performance from Lean efforts on the shop floor.
The “Lean” methods discussed in this Toolkit are organizational improvement methods pioneered in the Toyota Production System. Lean production and Lean manufacturing refer to a customer-focused business model and collection of methods that focuses on the elimination of waste (non-value added activity) while delivering quality products on time and at a low cost. The toolkit assumes that you are familiar with Lean methods and their implementation. For those who want to learn more about Lean methods discussed in the toolkit, see Appendix A.
Lean works well when it focuses on identifying and eliminating non-value added activity. Environmental improvement efforts that have potential to distract Lean efforts from this prime focus will likely not get much traction. By contrast, this toolkit contains strategies and techniques that can seamlessly enable Lean practitioners to easily identify environmental wastes and improvement opportunities alongside the myriad other wastes and improvement opportunities uncovered by Lean. To accomplish this, the toolkit aims to answer the following questions:
What is environmental waste? Environmental waste is an unnecessary or excess use of resources or a substance released to the air, water, or land that could harm human health or the environment. Environmental wastes can occur when companies use resources to provide products or services to customers, and/or when customers use and dispose of products. Chapter 2 defines and provides examples of environmental waste.
Why should I identify environmental waste in my processes? Environmental wastes do not add value to the customer. Environmental wastes can also directly affect production flow, time, quality, and cost—making them ripe targets for Lean initiatives. In many cases, the costs associated with pollution and wasted energy, water, and raw materials can be significant. This chapter (Chapter 1) discusses the business case for eliminating environmental waste.
How will I know when I see environmental waste? Some environmental wastes are easy to see. Containers of solid and hazardous waste are visual indications of environmental waste. Health and environmental risks posed by certain chemicals or materials can be more difficult to see, although they can represent costly non-value added aspects of a process or product. Chapter 2 provides examples of environmental wastes and describes organizational strategies that will make it easier to know when you see them.
Where should I look for environmental wastes? Environmental wastes can be found in almost any process. Processes requiring environmental permits—such as painting, metal finishing, and hazardous waste management processes—are often a good place to look for environmental improvement opportunities. If your organization has an environmental management system (EMS), your EHS personnel may have already identified key environmental impacts associated with each of the organization’s processes. Chapter 3 discusses how value stream mapping (VSM) tools and techniques can be used to help Lean practitioners see environmental wastes in processes. Chapter 4 discusses how to identify and address environmental wastes during kaizen rapid improvement events.
How do I measure the environmental impacts of a process? Measurement of key environmental wastes associated with a process can pinpoint those wastes that are most important to track over time. For example, chemical use and hazardous waste generation may be important to measure for one process, while water use may be most important to measure for another process. Chapter 3 discusses techniques for integrating environmental metrics into value stream maps. Appendix B includes information on environmental metrics that are often used by companies and facilities.
Where can I find environmentally preferable alternatives to my current process? EHS professionals in your organization may have ideas and information regarding environmentally preferable processes, equipment, and materials. In addition, numerous organizations, including EPA, have developed technical assistance resources and programs to assist organizations to improve the environmental and operational performance of processes. Chapter 4 discusses several useful resources and technical assistance networks. There are also Pollution Prevention Resources in Appendix D.
Explicit consideration of environmental goals and opportunities during Lean implementation can create significant value for an organization—helping to deliver quality products and services that customers want, when they want them. Research sponsored by EPA and others shows that environmental performance benefits typically ride the coattails of Lean efforts, yet these efforts may overlook other opportunities to reduce wastes and non-value added activity. Adding environmental considerations to Lean efforts can increase value, accelerate Lean implementation, decrease material costs, and reduce liability and the risk of compliance violations.
Below are three key reasons why business leaders, Lean practitioners, and environmental, health, and safety (EHS) managers have pursued efforts to coordinate Lean and environmental management activities.
Learning to see and eliminate waste is a cornerstone of Lean initiatives. There is one type of waste, however, that often goes unaddressed (or under addressed) by Lean initiatives—environmental waste. When grouped together, environmental wastes can result in huge costs to business. These costs include raw material and disposal costs, as well as costs for compliance management activities and pollution control equipment.
Lean’s focus on eliminating non-value added activity is excellent at driving down the volume of material, water, energy, chemical usage, and wastes, producing important competitiveness and environmental benefits. The environmental risk and full lifecycle impacts that materials and chemicals pose to human health and the environment, however, are rarely considered during Lean implementation. Learning to see environmental wastes during Lean efforts can open significant business improvement opportunities, further strengthen Lean results, and improve environmental performance.
Environmental wastes are often a sign of inefficient production, and they frequently indicate opportunities for saving cost and time. The chemicals and hazardous materials used in a process often demand costly support activities, such as regulatory compliance management and reporting activities, use of personal protective equipment, and the investment, operation, and maintenance of pollution control equipment. These activities do not add value to the customer, and they can create unnecessary risks to worker health and safety.
Chemical substitution, process changes, and other strategies can reduce the need for such non-value added activities. For these reasons, learning to see and eliminate environmental wastes can greatly improve the time, quality, and cost results of Lean initiatives.
Explicit coordination of Lean and environmental initiatives can lead to compelling organizational and environmental improvement results. For example, Lean thinking can be applied to various environmental management processes, such as chemical and waste management. Companies have found that as much as 40 percent of their chemical supplies were going unused and directly becoming hazardous waste as they expired on the shelf or became obsolete. Using Lean principles to improve chemical and waste management processes can have big pay-offs for environmental performance and bottom-line results.
Proactive Lean and environment coordination can also anticipate and ease environmental constraints to leaning “monument” processes, thereby enabling large performance gains. Monuments are production processes or process steps that have large equipment and/or other physical or environmental regulatory constraints that make them very difficult or costly to move, which can complicate Lean efforts. Typical monuments include painting and metal finishing processes.
Making changes to monument processes can require approval or permits from environmental regulatory agencies, as well as special work practices or control measures, all of which can be difficult to accomplish within rapid timeframes. EHS personnel can help to identify environmentally friendly process alternatives, and ensure that process changes can be made as quickly as possible.
Most customers who purchase products do not want to buy environmental wastes, impacts or risk. Companies that can deliver products and services with fewer environmental impacts have the potential to capture significant competitive advantage, provided that there are not sacrifices in time, quality, or cost. In many markets products with superior environmental performance can attract new customers.
Explicit consideration of environmental waste in Lean initiatives can also improve the work environment for employees. Similar to ergonomic concerns, eliminating environmental hazards can reduce potential worker exposure to toxic substances and create a clean, safe workplace.
In addition, employees want to do the right thing. When employees take pride in their work because they believe it has broader benefits to their community and the world, there can be a substantial positive effect on organizational morale. This can empower employees and further enhance productivity.
This toolkit provides practical strategies, tools, and techniques for incorporating environmental considerations into already existing Lean initiatives in an effort to improve Lean results and add value to your organization.
There are three key reasons why business leaders, Lean practitioners, and EHS managers pursue efforts to coordinate Lean and environmental management activities.
- Learning to see and eliminate hidden environmental wastes during Lean implementation can lead to more efficient production by improving the time, quality, and cost results of Lean initiatives. Chemical substitution, process changes, and other strategies can reduce the need for non-value added activities—such as regulatory compliance management and investment in pollution control equipment—that might otherwise be overlooked by Lean alone.
- Coordination of Lean and environmental management can facilitate more process improvement and make it easier to apply Lean to processes with environmental regulatory constraints. EHS personnel can assist Lean implementation by anticipating and addressing environmental constraints such as the need to obtain permits, and by identifying environmentally friendly process alternatives.
- A significant competitive advantage can be attained by providing customers with products and services with less environmental impacts, and by improving the work environment for employees.
