GREEN MANUFACTURING • “We borrow the Earth from our descendants” • Depletion of resources • Polluting the environment
GREEN MANUFACTURING • Enables economic progress • Minimize pollution and waste • Conserve resources
GREEN MANUFACTURING • Manufacturing methods that support and sustain a renewable way of producing products and/or services that do no harm to you nor the environment.
POLLUTANTS • • Careless disposal of waste Newly identified toxins "Big Company problem". . . right? Toxic hazards present in everyday household products - Food - Synthetic fragrance
POLLUTANTS • "Many times, because of extensive use, we assume a product is safe. But any chemical ingredient warrants a closer look, no matter how long it's been on the market. We need to ask ourselves whether we should be careful of using such ingredients on a daily basis, and if necessary, we should explore other options for our customers. ”
CHOICES • Use natural raw ingredients, including organics • Do not use hazardous chemical conditioners, chemical anti-bacterials or chemical preservatives • Use botanically-derived, colour, spices etc • Cold manufacturing process for soap
DEPLETION OF RESOURCES & INCREASING POLLUTION • As much fresh water has been withdrawn in the last 30 years as in the last three centuries. • Globally, there is a 160 billion cubic meter overdraft of groundwater per year. • The rate of increase in atmospheric carbon dioxide between 1970 and 2000 is nearly double that between 1960 and 1970 (1. 5 ppm vs. 0. 88 ppm per year).
DEPLETION OF RESOURCES & INCREASING POLLUTION • Carbon emissions have increased by more than 1. 5 times since 1970. • The U. S. , EU and Japan are by far the world’s biggest producers of solid waste, with the U. S. at about 14 times that of Japan and the EU combined. • Solid waste strategies: In Japan, it’s "Minimize at source"; In Europe, it’s "Producer responsibility"; In the U. S. , it’s "There’s always more space
WASTE GENERATION • Manufacturing generates maximum wastes
NATURAL RESOURCES • Natural resources are vital to - Economic activity - Personal satisfaction - Health • Need to be preserved for future generation • balancing environmental and business needs
COST & GREEN PRACTICES • Gap remains between societal benefits and private business benefits. But that gap may be narrowing • Examples - Compact fluorescent lightbulbs, - Software distribution via the Internet, - Hybrid electric vehicles - More efficient refrigeration
IS IT WIN • What's good for the environment is good for business ? • Regulation can confer specific and narrow benefits on some firms at the expense of others. • Example : Montreal Protocol Wiped out the market for commodity CFCs Benefited Dupont and ICI
SUSTAINABILITY • Using regulatory actions to secure production cost advantages • Sugar Industry : bagasse & mud paste • Molasses to Alcohol - What remains after taking out alcohol - Highly toxic - Discharged on land or in to river
SUSTAINABILITY • Metalworking fluids (emulsions of oil, water and stabilizing agents) - 12 percent of metals manufacturing costs - Limited reuse & high cost of disposal -Environment friendly vegetable oil substitutes -Microfiltration techniques to extend the useful life of these fluids virtually indefinitely
SUSTAINABILITY • Public and industry awareness campaigns • Adding business value can drive environmental solutions to "self-assemble“ • Corporate involvement
GLOBAL MARKET • Overseas environmental regulations • Growing consumer demand for a new generation of environmentally friendly products • Green products and production techniques are a competitive weapon • Example (1) European directorate for the environment said it would eliminate brominated flame retardants used in electronics
GLOBAL MARKET • Siemens could not find a replacement • Sony Corp. produced a viable alternative • Example (2) -New clean air emissions limits for automobiles -Honda and Toyota produced new engines to meet and exceed requirements.
