Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA Prepared by RITs National Center for Remanufacturing and Resource Recovery
Hundreds of millions of computers... obsolete. *National Safety Council Each year, 500 million cubic feet of non-recyclable waste is generated from auto recycling activities. The Problem: Environmental Trends
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
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 Remanufacturing vs. Recycling
Life Cycle of a Product
Conserves Energy - avoids energy requirements in raw material acquisition & processing, portion of manufacturing n manufacturing one new automotive starter requires more than 11 times more energy than remanufacturing a starter Benefits of Remanufacturing
n manufacturing one new starter requires more than 9 times more new material than a remanufactured starter n manufacturing one new alternator requires more than 8 times more new material than a remanufactured alternator Benefits of Remanufacturing Conserves raw material
– 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 Prevents pollution
Benefits of Remanufacturing Cost-effectiveness n Unlike recycling, remanufacturing preserves a products added value – the labor, machinery and production invested to turn raw materials into a product n A remanufactured product costs on average 50% less than a new product
Benefits of Remanufacturing Provides jobs n Labor intensive - employs many people n Jobs for low/unskilled workers n Jobs for highly trained engineers
What products are remanufactured?
What Products are Remanufactured? n anti-lock brakes systems n air conditioners n alternators n armatures n air brakes n brake cylinders n ball bearings n brake shoes n calipers n carburetors n cruise control n cylinder heads n clutches n crankshafts n constant velocity drive shafts n differentials n drive shafts n distributors n electronic control modules n engines n engine parts n fan clutches n fuel injectors n fuel pumps n front wheel drive axles n generators n master cylinders n oil pumps n power brake unites n power steering gear n power window motor n power steering pumps n rack & pinion steering units n rotors n starter drives n speedometers n solenoids n smog pumps n starters n stators n throttle body injectors n torque converters n transmission parts n transmissions n turbochargers n voltage regulators n wiper motors n water pumps automotive
Some Examples of Remanufacturing
How Do They Remanufacture... Kodaks redesigned Fling cameras* n Snap closures for body pieces means cameras are disassembled instead of broken apart. n 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: Single-Use Cameras?
What is the Benefit of Remanufacturing … n ~52 million cameras (or 3.9 million pounds of material) were remanufactured in one year - higher than the recycling rate for aluminum cans. n 67% less energy is required for manufacturing process of the cameras Single-Use Cameras?
How Do They Remanufacture... n Remanufactured components include: cylinder block, cylinder head, crankshaft, camshaft, & connecting rods. n Wearable parts - bearings, rings, pistons and gaskets - are replaced. n (Many remanufacturers offer better warranties than OEMs.) Automotive Engines?
What is the Benefit of Remanufacturing... n Energy savings of 50% n Remanufactured engines cost $800 to $ versus the cost of a new car Automotive Engines?
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
Clean technologies Vision: Develop cost-effective technologies that promote transformation of conventional factories to eco-efficient, safe factories. - little or no hazardous material - highly resource efficient: raw materials, energy, water - safe for workers, the public and the environment
Approach: Integrated approach to process development, transfer & evaluation –technical – economic – energy efficiency – resource efficiency – environment, health & safety Clean technologies
Automotive Parts Cleaning Project Objective: Identify, evaluate, and transfer cleaning technologies that are – cost-effective – environmentally sound – energy efficient Worked with 23 partner companies in New York State Constructed Surface Cleaning Evaluation Facility Generated significant savings in energy and operating costs for several companies
Project Results – Arc Remanufacturing Replaced mid-pressure spray washer with high-pressure spray washer Reduced electricity consumption by 1,200 KWH/year Extended cleaning bath lives from 3 weeks to 6 weeks Eliminated precleaning and rework processes, saving labor Saved $105,000/yr from an installed equipment cost of $67,000 Generated 8-month payback period on investment from just one part type
Project Results – D&W Diesel Installed washwater filtration system Reduced electricity consumption by 12,600 KWH/year Reduced consumption of natural gas by 79,000 cubic feet/yr Extended cleaning bath lives from 4 weeks to 3 months Saved $5,300/yr from an installed equipment cost of $7,200 Generated 16-month payback period on investment
Expert System Project Objective: Create a computerized tool to efficiently develop customized cleaning system improvement recommendations Worked with partner companies in New York State to test- drive coded system and implement results 4 industries evaluated: –Transmission rebuilders –Aircraft engine rebuilders –Machine tool manufacturing –Locomotive turbocharger remanufacturers
