1.1 Introduction to Tire Recycling Industry
There are over 285 million tires discarded annually in the United States and 1-3 billion are currently in landfills. About 75% of the discarded tires are placed in landfills annually, and though they represent only 1% of municipal solid waste, they are not biodegradable and pose significant environmental problem. The scrap tire recycling industry in the United States has grown rapidly since 1986. For more than quarter of a century, the tire recycling industry has explored ways to use recycling tires as a raw material in manufacturing new products. These innovations have turned what might have been a waste into a specification grade recyclable industry.
Every two weeks, Americans wear almost 50 million pounds of rubber off their tires. That’s enough to make 3.25 million new tires from scratch. The Environmental Protection Agency reports 290 million scrap tires were generated in 2003. Of the 290 million, 45 million of these scrap tires were used to make automotive and truck tire re-treads. The United States has decreased the number of waste tires in storage from 700-800 million in 1994, down to 275 million tires in 2004 primarily due to state scrap management programs.
At the end of 209, the Unites States generated approximately 290 million scrap tires. In the United States of America, scrap metal processors recycle the following estimated quantities on an annual basis:
· 56 million tons of scrap iron and steel
· 1.5 million tons of scrap copper
· 2.5 million tons of scrap aluminum
· 9 million tons of scrap automobiles
· 1.3 million tons of scrap lead
· 300,000 tons of scrap zinc
· 800,000 tons of stainless steel scrap
In Maryland, you pay a fee of $.80 as recycling fee when you buy a new tire. Funds collected from the tire fee support Scrap Tire Program that is dedicated to ensuring the cleanup of illegal scrap tire stockpiles and to managing the collection, transportation and processing of the scrap tires.
Consider that the average American family owns two cars with four tires each which need to be replaced every two years. In Maryland, that adds up to almost 5.5 million new scrap tires each year requiring proper disposal. Any person who transport, collects, processes, recycles, disposes, incinerates, or utilizes scrap tires as tire derived fuel will require the appropriate license.
1.2 Pyrolysis Process
Pyrolysis is process of molecular breakdown where larger molecules are broken down into small molecules. Pyrolysis plant is an industry designed to carry out pyrolysis of waste plastic &tires. In case of plastic & tires pyrolysis, long chain polymer is broken down into smaller chains of hydrocarbon gas and pyrolysis oil. Heat and catalyst are required for the following reaction.
1.2.1. Output Products:
Fuel oil (40 to 45%):
The main oil product produced by recycling application is the fuel oil, which is wide used for industrial and commercial purposes. The oil has 40%-45% of the amount of recycled scrap tires, which will be carried with licensed tanker trucks.
Carbon black (30 to 35%):
Carbon black is the main product recycled by the pyrolysis technology. The amount of recycled carbon black is 30%-35% (depending on the type of tire) of the total amount of scrap tires recycled in the system. Carbon black is used as raw material or main ingredient in many industries and the chemical structure of carbon black strengthens, lengthens the endurance, and improves the coloring features of the materials.
Carbon black produced by pyrolysis application (CBp) is more economical compared to carbon black produced primarily from petroleum and is more price-efficient. It is to be used as an ingredient in the following industries:
* Electric cable jacketing
* Conveyor bands
* Carrier bands
* Home and doormats
* Black nylon bags
* Rubber additives
* Automotive spare parts
* Heat isolation
* Black colorant in rubber materials
* Plastic pipes
* Industrial rubber products
* Fire fighting
Steel wire (15 to 20%):
Tires contain steel wires, the amount ranging from 15% to 20% of the total tire weight. All of the steel present in the tire can be detached after the pyrolysis recycling process is completed. Valuable steel wires are pressed and sold to steel and scrap dealers.
Gas (5 to 7%):
Non-condensable gases arise during the recycling application which:
* Has a higher calorific value compared to natural gas;
* Can replace natural gas and propane when stored;
* Can be used as energy resource in gas burners, also used in pyrolysis system.
The amount of gas generated in the system is 5 to 7% of the total amount of recycled tires and considering the 9 ton scrap tire/day recycling capacity, the facility generates 1400 – 1500 m?/day gas which has an enormous energy potential when evaluated.
1.2.2. Features of Pyrolysis Recycling Plant:
* 90% waste tire recycling will be achieved (no churn left after the process).
* No chemical ingredients are used in the process (the process is completely environmental-friendly).
* During and after the process no soil, water or air pollution is observed.
* The process creates economically valuable products out of waste (all of the products are industrial raw materials that have a market value).
* The most cost-effective waste tire recycling technology in the world.
* Raw material (waste tire) is cheap and easy to provide. These are the by-products of tire production.
* Each recycled ton of tire preserves 9 tons of CO2 that is a major greenhouse gas.
* The process can be applied to all rubber based materials.
* The system creates an alternative source of energy to replace petroleum products and natura lgas.
* The system gives the opportunity to governments and local administrations to deal with the waste tire problem to a great extent.
* The system prevents the spread of diseases caused by waste tires..
* The process of Pyrolysis has duration of 4 to 12 hours, depending on the amount and type of tire (car tire, truck tire, etc.). During the process different vacuum values are applied in pre- determined temperatures and in different phases different gases are obtained and the condensed gas is stored as fuel-oil in tanks.

The materials needed for the construction of Tire recycling plant will be determined during the design process. The materials used to construct the plant must remain within the designated cost for materials and production. All materials will be acquired in accordance with the Acquisition Plan.
4. ACQUISITION PLAN
4.1 Purpose of plan
The purpose of making this acquisition plan if to obtain all required materials for the construction of scrap tire recycling plant in Maryland through various contractors in Maryland and around DC on time without any schedule or cost delays. The plant has to fulfill its deliverables as mentioned already in the report. We would be setting up the new plant at a new place so we will need to acquire all the materials needed for its building on time. It will include everything from architecture designing, construction of the facility & warehouse, getting the machinery set-up, also all other aesthetics also like water supply equipment &electrical supply and other amenities also. For acquisition of these materials we will need to use COTS & for acquiring the machinery we will need to give out contracts through selection procedure as also discussed in report.
4.2 Conditions of applicability
The whole set-up needs to be in line with all the environmental conditions & rules applicable in the area as per the government. The set-up should have enough infrastructures for its working like access through industrial roads & even if through railroads. It should have enough capability to process the minimum amount of tire recycling per working hour of the plant. The completion of the project as stated earlier in scheduling & it should be completed within time. The cost of the plant should also exceed its budget. All the waste materials during this construction have to take proper care of & waste water used should be treated & cleaned before dumping off.
4.3 Acquisition costs.
The cost of acquiring all the materials required should not exceed $250,000 as mentioned in the budgeting of this report. We reached to this figure through extensive research of the other similar project studies. The cost of acquiring the architectural designs for the plant should not exceed 150,000 as also mentioned before which we reached to through researching how much generally it costs for architectural designing of such big projects. The acquisition cost of the machine setup should also not exceed 90,000 as described in details in contracting.
4.4 Performance deliverables
The project should follow the performance deliverables as mentioned in the requirements.
4.4.1 Architectural design

4.5 Acquisition trade off’s
4.5.1 Plant performance
The plant should able to process 9 ton of recyclable tires with 5 ton of water availability & would take 25 KW amount of electricity. It will produce this much oil, shredded tire, steel wires etc. while in operation.
4.5.2 Architectural trade-off
If the architectural contractor is not able to deliver the requirements then there might a trade- off potential to so as to not encounter schedule constraints.
4.5.3 Material suppliers
If the project faces some scheduling problems then a possibility of trade-off between material supplier is possible.
The biggest possibility of trade-offs exist among the aesthetic material in the project like lighting fixtures, air conditioning, plumbing etc. if the project starts to run into budget constraints.
4.6 Acquisition risks
4.6.1 Materials availability
After the architectural design has been finished and the required materials have been determined the risk comes into the availability of the raw materials required by amount or by delivery dates.
4.6.2 Man & machinery availability
Once all the material required to start the construction has been obtained the availability of manpower required and the machines that will be needed in construction may run into risk on their availability dates.
4.6.3 Contractor relations
The acquisition team will need to contract the proper contractors around the area to get the structural supplies for the project. For the machinery which have a potential to be delivered through a foreign contractor the risk of schedule and cost may go till the issues of import/export controls have been sorted out on both sides.
4.6.4 Schedule & cost risks
It is known to everyone very well that majority of the projects run into costs & schedules overruns once the project starts. As we know that we cannot have all the material required for the whole construction in hand beforehand the construction start so it increases a possibility of risk of having cost & budget over-runs.
4.7 Source-selection procedure
4.7.1 Inviting bids
Bidding of the project will be invited by construction companies that are willing to take up this project. A bid will tell us in how much money the construction management company is willing to complete the project. The bidding process will be a closed bidding process.
