Abstract
The Acrylic Bathtubs Plant Misr II is one of the two main production sites for
acrylic baths of Ideal Standard International and is engaged in the production
of the standard baths.The annual production capacities of MisrII is approx.
410,000 baths. Total site area is 7,800 m² and the built up area by building
and structures is 7,060 m².The remaining 760 m² around and between the
buildings is used to store ready products, base materials and molds. Process
hazards are enhanced/very high due to handling, processing and storage of
considerable amounts of flammable resins and harder; the spraying of
polyester resins and the trimming (drilling, grinding and sawing).
The plant located at Industrial Zone (B4)10th of Ramadan City.
The study Aim is to:
5- Decrease the Environmental Impact of using Acetone, which mixed
with resin, and Catalyst
6- Decrease the amount of acetone used by Treatment and recovery of
used acetone, which mixed with resin and Catalyst
7- Assessment and Monitoring of Workplace and organic Hazardous
waste resulting from the production of acrylic Bathtub
8- Treatment and Recovery of Hazardous waste
1- Decrease the Environmental Impact of using Acetone, which
mixed with resin, and Catalyst
Ideal Standard International Bathtub Plant consumed about, 72940 K.G /
Year from Acetone which used as solvent to cleaning the brush after
contaminated with Resin and Catalyst, this process generated about 65520
K.G / Year because some quantitates are evaporated to air which cause harm
effect to Ambient Air , the company disposed all this waste as Liquid
64
hazardous waste by Authorized Company for transportation and treatment of
Hazardous Waste from EEAA, the cost for transportation and treatment 1700
L.E/Ton, thus the total cost for transportation and treatment before our study
= 111,384.00 L.E( 66 Ton ) , but after study the cost was = 26732.16 L.E ( 18
Ton 24% Solid waste Remaining after recovery of acetone ).
2- Decrease the amount of acetone used by Treatment and recovery of
used acetone, which mixed with resin and Catalyst
The total waste generated about 65520 K.G / Year, the company disposed all
this waste as Liquid hazardous waste by Authorized Company for
transportation and treatment of Hazardous Waste from EEAA. But after
apply our study we able to recovery about 49,795.20 K.G (76%), meaning
that the company will buy only 23,144.80 K.G which cover all yearly
Requirement from Acetone which is 72940 K.G. thus the revenue = 796,723

3- Assessment and Monitoring of Workplace and organic Hazardous
waste resulting from the production of acrylic Bathtub
Measurements of air contaminates (PM10, Pollutant gases, Heat stress, Noise
Intensity, Light Intensity and exhaust stack emissions).The results showed
that air quality in work places are within the permissible limit according to
law 4/1994 for Environment protection and its amendments by law
No.9/2009 and its executive regulation issued in 1995 and its amendments
issued in 2012 and Labor Law no. 12 /2003.
The Concentrations of Thoracic Particulate (PM10) are less than the
maximum permissible limits according to the Environmental Law no.4/199
for Environment protection and its amendments by law No.9/2009 and its executive regulation issued in 1995 and its amendments issued in 2012 and
Labor Law no. 12 /2003. ( 3 mg / m3 ) , except lamination area exceed the
maximum permissible limits according to Law No. 4/94 for Environmental
protection and its amendments by Law No. 9/2009 and its executive
regulation issued in 2012, so worker in these areas should wear filters for
dust and increase the ventilation system in these areas.
The Noise level measurements in some work places exceed the permissible
limit according to law 4/1994 for Environment protection and its
amendments by law No.9/2009 and its executive regulation issued in 1995
and its amendments issued in 2012 (90)dB. Therefore the company should
apply the safety regulations for exposure time and the workers in these
points wear ear plugs. The Heat Stress are less than the maximum
permissible limits according to the Environmental Law no. 4/1994 for
Environment protection and its amendments by law No.9/2009 and its
executive regulation issued in 1995 and its amendments issued in 2012and
Labor Law no. 12 /2003.
The light intensity complying with the work law no. 12/2003
The concentration of gases and vapors are less than the maximum
permissible limits according to the Environmental Law no. 4/1994 for
Environment protection and its amendments by law No.9/2009 and its
executive regulation issued in 1995 and its amendments issued in 2012and
labor law no. 12 /2003. The Exhaust Stack emissions are less than the
maximum permissible limits according to the Environmental law no.
4/1994 for Environment protection and its amendments by law No.9/2009
and its executive regulation issued in 1995 and its amendments issued in
2012and labor law no. 12 /2003.

About the management of hazardous and nonhazardous waste the company
comply with Environmental law 4 to year 1994 which integrated by law 9
to year 2009.
4- Treatment and Recovery of Hazardous waste
In the present study the different samples of waste resin from different
patches were collected in closed Standard Waste Can to prevent the
vaporization of wasted acetone which lead to lose of the liquid layer and the
amount of pure acetone obtained will decrease .The shift time in spraying
area is 8 h and the waste acetone which mixed with resin and catalyst is
changed after 5h because the acetone lose its function but we found that to
obtain a good result for recovery of large amount of pure acetone , the
workers need to change the waste acetone with new acetone after 3h of work.
Then the liquid layer was distilled on water bath to obtain the pure acetone to
reuse it. The recovered acetone was (76.7%) from the total amount of used
acetone during the industry process. The remaining solid waste (23.3%) is
under investigation. This experiment was repeated at different seasonal time
from winter to summer and the result obtained show that the approximately
amount of recovered acetone was (76.7%) from the total amount of used
acetone.
