Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

1. Pulp and Paper Processes for
Sustainable Production
Keith Larson
2. History of Paper Making
105 A.D. Ts'ai Lun, a Chinese court
official, invented paper
mulberry bark, hemp and rags with water
Paper was first produced in Egypt
around 900 A.D.
England early in the 14th Century
To this point all paper and
books were produced by hand
3. History of Paper Making
Gutenberg Press in 1436
On September 30, 1452
Guttenberg's Bible was published
The printing press allowed
printed materials to be
produced at a greater rate
thus increasing the demand
for paper
4. History of Paper Making
First North American paper mill in
1690 near Philadelphia
America's first writing papers were
produced by collecting, separating,
and cleaning old cloth rags
The paper was made in single sheets
5. History of Paper Making
1798, Nicholas-Louis Robert of
France invented a paper making
machine that produced paper on an
endless wire screen
Further developed in England by
Brian Donkin
Not put into service until 1804
6. History of Paper Making
The Fourdrinier
1st Fourdrinier machine
in the US, 1827
7. History of Paper Making
1866
American Benjamin
Tilghman developed
the sulfite pulping
process
Dominant pulping
process until the
1930s
1879
German chemist, C. F.
Dahl, developed the
Kraft pulping
process
1930s dominant
pulping process
and still is today
Two major advancements in pulping were
developed in the late 1800s
8. Advantages of the Kraft Process
The majority of the chemicals used in
the pulping process are recoverable
for use in further pulping operations
Large amounts of energy are
produced in the recovery boilers
during the recovery process
The Kraft process can pulp pine trees
9. Pine trees are abundant throughout much
of the United States. The Kraft process
allowed the United States to become a
major producer of paper products.
However, the Kraft process has created
environmental problems
Ocala National Forest, Dec. 1998
10. The Modern Paper Making Process
The process of making paper begins far from
the paper mill itself
Clearcut in Oregon's Coast Range
11. The Modern Paper Making Process
Paper Making Process Overview [Chesterton, 2004]
13. The Modern Paper Making Process
1) Mechanical Pulping
2) Chemimechanical
3) Thermomechanical
4) Chemimechanical and
Thermomechanical Pulping (CTMP)
5) Chemical Pulping
Five Methods of pulping
14. The Modern Paper Making Process
The chemical method is the most popular
because it produces a higher quality paper
than mechanical pulping
The most popular method of pulp production
is the Kraft process, producing nearly 85%
of all pulp in the United States
This will be the focus of the pulping

23. The Problems and Solutions
The pulp and paper industry came into
its own during a period when the
environmental effects of chemical
plants were not well understood, and
discharges were not well regulated
The operation of a pulp and paper mill
creates many environmental
concerns
24. The Problems and Solutions
One of the very first
impacts of the
paper industry was
the deforestation of
large tracts of land
in the early 1900s
Today the paper
companies practice
a process of
sustainable forestry
Brush Creek, Private Land, Oregon
25. The Problems and Solutions
The Sustainable Forest Initiative program
was developed in 1994 by the American
Forest & Paper Association to ensure
forests are protected
“responsible environmental practices and
sound business practices can be
integrated to the benefit of landowners,
shareholders, customers and the people
they serve” [aboutsfi, 2004]
26. The Problems and Solutions
For every tree
harvested today, the
paper companies are
planting five seedlings
There is now more
forestland than in
1970
The Sustainable Forest
Initiative has been a
success
27. The Problems and Solutions
Many environmental concerns
surround water usage
Release of Hydrogen Sulfide (H2S)
and Sludge
Creation of Dioxins and Furans
BOD, COD, TSS
28. The Problems and Solutions
Hydrogen Sulfide
Hydrogen sulfide is a toxic gas that smells
like rotten eggs
At elevated levels, it can irritate the eyes
and respiratory system
It can be deadly at very high levels (greater
than 500,000 parts per billion)
29. The Problems and Solutions
No current Federal Limits on H2S
In January 2000, EPA issued a
Federal Register notice announcing
H2S is one of the chemicals for which
EPA is developing a health
assessment
Individual States are setting limits
30. The Problems and Solutions
Dioxins and Furans
Most toxic chemicals known to
science
The most toxic compound is 2,3,7,8-
tetrachlorodibenzo-p-dioxin or TCDD
Any process that uses chlorine can
change or generate chlorinated
dioxins and furans
White Paper bleaching uses Chlorine
32. The Problems and Solutions
Reduction of Wastewater
Reduce the demand for the high
quality bright-white paper
For “lower quality” papers use a
combination of other chemicals in the
bleach process (oxygen for example)
Do a better job of pulping the wood
33. The Problems and Solutions
Ash and smoke,
byproducts of
burning the
black liquor and
fuel in the
recovery boiler
and power
boiler, escapes
thru the smoke
stacks
34. The Problems and Solutions
Improved electrostatic precipitators
are being installed to help prevent
the release of ash and smoke into
the atmosphere
The process of concentrating the
black liquor has been improved
Use cleaner burning fuels
35. Hope for the Future
Still have a long way to go to prevent any
environmental impact
Operating a paper mill is a balancing act
Cost
Quality
Environment
Time
36. Hope for the Future
Advances Toward Sustainability
Sustainable Forest Initiative Program
Recovery of Process Chemicals
Recycling of Process Water
Reduction of Dioxin Production
Make use of by-product Residue
Tall Oil – used in paints, perfume, cosmetics
Turpentine
37. Hope for the Future
“responsible environmental practices and sound
business practices can be integrated to the
benefit of landowners, shareholders, customers
and the people they serve”
