Energy Efficiency and Environmental Protection through Remanufacturing Prepared by RIT’s National Center for Remanufacturing and Resource Recovery Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA
The Problem: Environmental Trends Each year, 500 million cubic feet of non-recyclable waste is generated from auto recycling activities. Hundreds of millions of computers ... obsolete. *National Safety Council
One Solution: Remanufacturing The “Ultimate Form of Recycling”
What is Remanufacturing? An industrial process in which non-functional or retired products are restored to like-new or improved condition.
What is Remanufacturing? Primary components come from a used product Product is dismantled Condition of parts determined Components cleaned and restored to original or “better than new” specifications Product is reassembled and qualified
Remanufacturing vs. Recycling Example: Office Chairs Recycling: Strip worn fabric and convert to industrial padding Send metal frames to resmelting Form resmelted metal into a new product Remanufacturing: Replace fabric covers Repair and repaint metal frames Replace worn-out parts, e.g. fasteners
Life Cycle of a Product
Benefits of Remanufacturing Conserves Energy - avoids energy requirements in raw material acquisition & processing, portion of manufacturing manufacturing one new automotive starter requires more than 11 times more energy than remanufacturing a starter
Benefits of Remanufacturing Conserves raw material manufacturing one new starter requires more than 9 times more new material than a remanufactured starter manufacturing one new alternator requires more than 8 times more new material than a remanufactured alternator
Benefits of Remanufacturing Prevents pollution avoids emissions from raw material acquisition & processing, portion of manufacturing unlike recycling, metals are not resmelted (a highly air polluting process) prolongs product life and keeps products out of landfills and incinerators
Benefits of Remanufacturing Cost-effectiveness Unlike recycling, remanufacturing preserves a product’s added value – the labor, machinery and production invested to turn raw materials into a product A remanufactured product costs on average 50% less than a new product
Benefits of Remanufacturing Provides jobs Labor intensive - employs many people Jobs for low/unskilled workers Jobs for highly trained engineers
What products are remanufactured?
What Products are Remanufactured? automotive anti-lock brakes systems air conditioners alternators armatures air brakes brake cylinders ball bearings brake shoes calipers carburetors cruise control cylinder heads clutches crankshafts constant velocity drive shafts differentials drive shafts distributors electronic control modules engines engine parts fan clutches fuel injectors fuel pumps front wheel drive axles generators master cylinders oil pumps power brake unites power steering gear power window motor power steering pumps rack & pinion steering units rotors starter drives speedometers solenoids smog pumps starters stators throttle body injectors torque converters transmission parts transmissions turbochargers voltage regulators wiper motors water pumps
Some Examples of Remanufacturing
How Do They Remanufacture . . . Single-Use Cameras? Kodak’s redesigned “Fling” cameras* Snap closures for body pieces means cameras are disassembled instead of broken apart. 77 to 86% of parts are recycled or reused - cardboard was replaced by standardized, recyclable plastic. *1999 Annual Report. Health, Safety and Environment Department. Eastman Kodak Company. Available through: www.kodak.com
What is the Benefit of Remanufacturing … Single-Use Cameras? ~52 million cameras (or 3.9 million pounds of material) were remanufactured in one year - higher than the recycling rate for aluminum cans. 67% less energy is required for manufacturing process of the cameras
How Do They Remanufacture . . . Automotive Engines? Remanufactured components include: cylinder block, cylinder head, crankshaft, camshaft, & connecting rods. Wearable parts - bearings, rings, pistons and gaskets - are replaced. (Many remanufacturers offer better warranties than OEMs.)
What is the Benefit of Remanufacturing . . . Automotive Engines? Energy savings of 50% Remanufactured engines cost $800 to $2500 - versus the cost of a new car
Impact of Cleaning in New York State Cleaning is an energy-intensive process Significant amounts of hazardous wastes, solvents, and contaminated wash water are generated Cleaning is very labor-intensive Potential for competitive advantages 24,000 manufacturing companies are located in New York State, of which 4,800 are involved in remanufacturing
