Recycling Cost - Tennessee Environmental Conference
Ricky King Director of Safety & Environmental Affairs Lodge Manufacturing Company Sustainable: using a resource so that the resource is not depleted or permanently damaged . Foundries are some of the oldest recyclers. Foundry scrap can include a general mix of iron scrap metal that can include a wide variety of cast, plate & structural materials such as I-Beam, rebar, old cannons, lampposts, scrap locomotives, track …etc., etc. However, Lodge now uses a very clean metal mix in melting consisting of domestic pig iron, bushling steel from Tennessee stamping operations and our own returned gates, risers and off quality castings. If you ever wear out your Lodge cast iron skillet, we will gladly remelt it. Ancient Castings 9000 B.C.-Earliest metal objects of wrought native copper are produced in the Near East. 3000-2500 B.C.-Small objects are cast via lost wax investment casting process in the Near East. 3200 B.C. A copper frog, the oldest known casting in existence, is cast in Mesopotamia. 3000 B.C. Weapons and cult objects made of copper of this age recovered from middle east and India. AFS Birmingham 2000 B.C. Iron is discovered. 800-700 B.C. First Chinese production of cast iron. 645 B.C. Earliest known sand molding (Chinese). 500 B.C. First steel products were made in India 233 B.C. Cast iron plowshares are poured in China. 500 A.D. Cast crucible steel is first produced in India but the process is lost until 1750 when Benjamin Huntsman reinvents it in England. Industrialmetalcasting.com In 1620, the Pilgrims formed the first colony in the New World at Plymouth. In 1643, samples of ‘bog iron’ from Saugus mines were taken to England to search for financing. 1,000 pounds were advanced by various investors and the “Company of Undertakers for the Iron Works” was formed. The Saugus Iron Works in Lynn, MA was the first established in America. It is the site of the first integrated ironworks in North America, founded by John Winthrop the Younger and in operation between 1646 – 1668 Joseph Lodge was born in 1848 near Philadelphia, PA. Left an orphan while still a boy, he went to Wilmington, Delaware where he learned the machinist trade. He later went to Cuba as a railroad engineer and was captured with his crew during one of the “Cuban Rebellions” until freed by the Spaniards. Cuba’s Ten Years War for Independence was from 1868-1878. After Cuba, Mr. Lodge went to South America and secured a job as an engineer in the Peru Navy. After a trip around the Horn, he was appointed chief engineer on the flag ship. The “Huascar”, somewhere off the coast of Chile in the late 1870’s (painting by Peruvian artist Saldivar) Following a stint in the Peruvian Navy, Mr. Lodge became a Division Superintendent of the Railroad building in the Andes. In 1876, Mr. Lodge returned to the U.S. for a leave. He received news that a flood had washed the railroad away and he decided to remain in the U.S. In 1876, Joseph Lodge went to work for Southern States Coal, Iron & Land Co. in South Pittsburg, TN as manager for their saw mill, then master mechanic and later general superintendent of the blast furnaces. When Southern States was absorbed by Tennessee Coal, Iron & Railroad Co. in 1881, Joseph Lodge remained as President. While with Tennessee Coal, Mr. Lodge located and opened the coal mines in Whitwell, TN. In 1892 Joseph Lodge organized the Shuster Foundry in South Pittsburg for the manufacturing of soil pipe which was sold to the Central Foundry Company in 1899. While at Shuster, Joseph Lodge started Blacklock Foundry in 1896 naming it after the manager, friend and minister, Harry Blacklock. Following the sale of Shuster in 1899, Joseph Lodge became President of Central Coal & Iron Company. While at Central Coal & Iron, Mr. Lodge located and opened up coal mines in Kellerman, Al. Also while at Central, Mr. Lodge built furnaces at Holt, Al. In 1906 Mr. Lodge became the General Manager of Woodward Iron Co, in Woodward, Al. Mr. Lodge returned to South Pittsburg when the Blacklock foundry burned in 1910 and relocated it three months later to its current location. At that time he organized the Lodge Manufacturing Company. Mr. Lodge was 62 years old. Lodge Sugar Kettle Lodge hand pour and floor molding In 1950, Lodge became more automated. 50’s & 60’s 50’s & 60’s 50’s & 60’s Cupola, early 90’s Lodge changed from a Cupola to Electric Induction Melting in 1992 with the environmental improvement being the deciding factor. This choice resulted in winning the1994 Governor’s Award. Lodge became a Tennessee Pollution Prevention Partner in 2003. We will replace our two 4 ton per hour induction furnaces with two 10 per hour induction furnaces in October 2013. We will add a new sand system and a 250C Disamatic Molding Machine in June 2014. Building construction started in January of this year. Sand + clay + water = molding sand Compress sand into hollow mold Pour in molten iron Allow iron to cool Break the sand and metal apart Reuse sand for other molds Clean and grind iron castings Remelt gates, risers and off quality castings Season with food grade cooking oil Sear, fry or braise on the stove, bake in the oven or blacken on the grill We reuse molding sand by adding new sand, clay and water to return it to a good molding condition. As sand becomes too fine for use or is somehow considered to be unusable, it is put in our foundry sand landfill and held for beneficial use under the TDEC Beneficial Use Policy. This policy was the result of Industry & Government working together with help from the University of Tennessee Center for Industrial Services and the American Foundry Society. Non-toxic foundry sand can be beneficially used under the 1996 State of TN Division of Solid Waste Beneficial Use Policy. EPA Interim Research 2010 The reuse of foundry sand can conserve virgin resources, and reduce energy use and greenhouse gas emissions. 212 billion BTUs = The annual electricity for more than 5,500 homes 20,000 tons of CO2 = Removing 3,469 cars from the road. Metal concentrations in the samples were very similar to and often less than metal levels in native U.S. soils. The risk assessment demonstrated the beneficial reuse of foundry sand from foundries does not pose a threat to human health or the environment. There are two Stormwater Retention Ponds that were built by Lodge personnel for stormwater control. One was later expanded and a Weeping Willow was planted. Ponds help recharge the water table. A larger pond was later added as a Watershed Retention Pond at the property edge. These ponds collect sediment and reduce the amount that would eventually go to the Tennessee River. A simple smart choice to control run-off and also included a UTCIS consultation. Lily pads were started with one plant pulled out of a small Mississippi pond. Cattails line the sides of the ponds and shallow ditches to the ponds and were started with cattail seed provided by a supervisor. Fish appeared either from coming in on bird’s legs or Mother Nature rained fish eggs. Ponds are cleaned out every couple of years and the fertilized material is put on the landfill surface to facilitate grass growth. A recyclable foam was being used to separate skillets in packing. Although recyclable, most would not know what to do with it and they would trash it. The foam was not biodegradable. Lodge replaces the foam with paper to increase recycle potential. This simple change saved $12,267 the 1st year. Require a review of the Material Safety Data Sheet (MSDS) on every new chemical before it comes into your location. A hazard determination must be made on each chemical in your operation. It is simpler to keep it out of your facility than to deal with it later. This includes samples. Vendors must understand that they will need to dispose of any left over chemicals not used. Tennessee School Plant Management Association: The Truth about Bulb Crushing vs Intact Recycling 1/17/2011 www.tspma.com/news/2011/01/17/truthabout-bulb-crushing-vs-intact-recycling Regulations: Packaging regulations per the UW law Generators may simply place their intact spent fluorescent tubes back in the original box, (provided it is in good condition). Tape the box closed and label the box with one of the following phrases, “Universal Waste lamps” , “Used Lamps”, or “Waste Lamps”. The lamps are now ready to ship to the recycler. Recycling Cost The cost to properly recycle an intact 4ft. lamp using the State Contract is .16 cents each. Cost to properly recycle 1000 4ft. Lamps: $160.00 Regulations in Tennessee Prohibited from diluting or treating universal waste, except by crushing for volume reduction purposes in compliance with the Permit-by-rule requirement of Rule 1200-01- 11-.07(1) (c) 1(iv) or as otherwise provided in Rule 1200-01-11-.12. Prohibited from mixing in any hazardous or non hazardous waste with the crushed Lamps. No filters, tools, solid waste, etc., shall be placed in the container of crushed lamps. Detailed records regarding this operation must be kept and made available for review for At least three (3) years, including, but not limited to, the technology employed for the crushing unit. The handler immediately transfers any material recovered from a spill or leak to a container and has available equipment necessary to comply with this container that meets the requirements of Rule 1200 01-11-.03(4) (e), requirements. The handler ensures that the area in which the lamps are crushed is well-ventilated and monitored to ensure compliance with applicable Occupational Safety and Health Administration (OSHA) exposure levels for mercury. Employee Training A handler of universal waste lamps must train all employees who handle or have responsibility for managing them in a lamp crusher. The training must address proper handling and emergency procedures, including transfer of mercury from containment devices to appropriate containers. The crushed lamps are stored in closed, non-leaking containers that are in good condition (e.g., no severe rusting, apparent structural defects or deterioration), suitable to prevent releases during storage, handling and transportation. Labeling/Marking A handler of universal waste lamps and crushing device must label or mark the universal waste lamps or containers as specified below: 1. Universal waste lamps (Le., each lamp), or a container in which the lamps or crushed lamps are contained, must be labeled or marked clearly with anyone of the following phrases: "Universal Waste Lamp(s)", or "Waste Lamp(s)", or "Used Mercury Lamp(s), 2. Placing "Crushed ", as appropriate, first on the label. Average Start up Cost to Crush Lamps in Compliance Avg. DTC Cost Mercury Air Monitor (Jerome) Bag filters (2) Approved 55 gal. Metal drum Employee Training (per employee) Total Start up Cost $3500 $5000 $ 114 $ 65 $ 250 *$8929 Note:*This is the cost before the first lamp is crushed. Additional Cost and Recycling Cost HEPA Bag Filters $57 Ea. (changed twice per drum) 2 for $114 HEPA Cartridge (required to change after 10 Drums) $136 $136 Ea. Disposal of Filters *estimated avg. cost $350 (as hazardous waste) Recycling Cost (Avg. per drum) $365 Total Additional Cost $829 ( Approximately1000 4ft tubes) Please Note: CFL’s and HID lamps Cannot be run through a Drum Top Crusher Regulations: Packaging regulations per the UW law Generators may simply place their intact spent fluorescent tubes back in the original box, (provided it is in good condition). Tape the box closed and label the box with one of the following phrases, “Universal Waste lamps” , “Used Lamps”, or “Waste Lamps”. The lamps are now ready to ship to the recycler. Recycling Cost The cost to properly recycle an intact 4ft. lamp using the State Contract is .16 cents each. Cost to properly recycle 1000 4ft. Lamps: $160.00 VENDORS PROVIDE TOTES FOR MIXED PAPER AND WILL PICK UP ON A SCHEDULE OR CALL IN. CARDBOARD CAN BE BALED AND SOLD. RECYCLERS CAN PROVIDE A BALER AS PART OF AN AGREEMENT. Labor will be spent to handle cardboard and mixed paper regardless of what you do with it. Labor used to haul to the dumpster or to the baler will be about the same. Locating a baler closer to the source would reduce labor time and cost. Labor used to make money is preferable to labor used to spend money. Prices may vary, but landfill costs and hauling will be saved regardless. 2012 Cardboard/Mixed Paper Recycling: Income: Disposal saved: Hauls @$95 saved: Baler Rental: Balance 2012: $ 4,019 for 109 tons $ 3,006 at $27.50/Ton $1,235 for 13 hauls 0 $ 8,260 SAVED (2011: $9,735 SAVED) Lodge sells recyclable used oil to a local oil recycler who picks up on site. This oil is cleaned and recycled for sale as a clean oil. In 2012, 1,375 gallons of used oil were sold for $485 and saved us $1,375 in disposal cost. The majority of our oily waste is absorbent socks for soybean oil. We recently contracted Generation Green Recycling to provide absorbents, collection drums and pickup service. The oil contained in the absorbent media is to be drained out and refined. The absorbents are and brought back to reuse. Choose Century Gothic Font for your printing whenever possible. This will reduce the amount of printer ink usage by extending the life of your ink cartridge. We donate our cartridges to a local school. Lodge stopped purchasing disposable Styrofoam coffee cups at the end of 2012. This saved about $100 a year on average, but eliminated 3500 coffee cups a year from our waste. Use Programmable Thermostats Replace HID Lights with fluorescent Replace older florescent lights with higher efficient lights. Use motion sensors in low use areas. Cut off equipment when not needed. Use monitoring in selected high use areas.
