PART 1: INTRODUCTION 1.1 Research rationale:

In the whole process, the business background will be going hand in hand with the environmental protection When the living standards of people are on the rise and their learning level is increasing gradually, human needs are not just satisfied by getting all the material gains they can earn but they also need a good environment This is the reason why they want to redirect strategies to a sustainable development Nowadays, businesses targeting the optimization of profits do not stop or care to exploit natural resources, which pose a threat to the depletion of the world’s supply and trigger negative impacts on the environment such as: Air polution, water polution, poisoned waste,etc For manufacturers who invest in waste treatment, environmental protection places a burden on producing cost and reducing competition, thus it can reduce profits For their own benefit, businesses often overlook the common benefit of society So how to accomplish to develop economically to achieve sustainable development?

At this time, the primary response for sustainable developement is cleaner production The introduction of cleaner production (CP) has played a significant role

on the sustainable development CP helps to save the energy and natural resources, it even removes the waste lines with an effeciency up to 100% Today, the controlling pollution at the end of the pipe does not seem to be an efficient solution due to its low effectiveness and high cost Instead of that, the use of vertical pipes or CP has been prevalent CP is proactive and precautionary before the waste is generated Therefore,

if the enterprise applies cleaner production, it not only benefits many businesses but also society CP is one of the most important strategies of many countries

Implementing CP technology in the industry is a way to bring benefits to the economy and at the same time contribute to reducing environmental pollution, allowing enterprises to fulfill the requirements of environmental protection The application of cleaner production will also help businesses to build a good reputation and products that can compete in the domestic and foreign markets

Hoang Van Thu Paper Joint Stock Company is located in Quan Trieu Ward, Thai Nguyen City Hoang Van Thu Paper Joint Stock Company is considered as one of the cradles of Vietnam paper industry, with a long history of development and a unit that has boldly applied cleaner production in recent years, it has brought about very good results The company has solidified its name and position in the domestic and international market and contributed to the economic development of Thai Nguyen in particular and of Vietnam in general In order to contribute to a sustainable development and promote the application of cleaner production in enterprises located

in Thai Nguyen province, I conducted research named: “Evaluation of Cleaner Production strategies efficiency in carton paper production in Hoang Van Thu Paper

Joint Stock Company, Thai Nguyen city, Thai Nguyen province”

1.2 Research’s objectives

- Understanding the current status of production and the application of cleaner

production options at Hoang Van Thu Paper JSC., Thai Nguyen

- Evaluating the effectiveness of the company's cleaner production options

- Researching to improve and propose new Cleaner Production solutions to the company

PART 2: LITERATURE REVIEW

2.1 Cleaner production review

2.1.1 The formation and development of cleaner production

Facts show that industrial processes always cause environmental pollution due

to emissions, wastewater and solid waste

Figure 1: General diagram of industrial producing process

(Source: Heinz Leueuberger, 2000)

As the environment is threatened by the increase of the industry, the ways in which industrial pollution has caused environmental degradation have changed over time:

Ignore Dilution & dispersion

Treatment of pipe end Cleaner production

Producing process

emissions Material

Prevent the generation of waste at the source by using energy and materials in the

most efficient way, it means adding a rate of raw materials to the finished product

instead of eliminating it This approach began to emerge in 1980 with different ways

of "pollution prevention", "waste minimization" Today, the term "cleaner production"

is commonly used around the world to refer to this approach In the past, our way of thinking in addressing environmental pollution still focused on the use of traditional waste treatment methods without regard to their origin Therefore, the cost of waste management is increasing but the pollution is getting heavier The industry suffered severe economic consequences and discredited the market To get rid of this deadlock,

industry is becoming more serious in reviewing the CP approach

2.1.2 The general concept of cleaner production

According to the United Nation Environment Program (UNEP, 1994), cleaner production is the continuous application of an integrated environmental precautionary strategy for production processes, products and services to reduce all bad impact on the environment and people

For production processes, cleaner production involves the preservation of raw materials, water and energy, the elimination of hazardous materials and the reduction

of the volume and toxicity of wastes into water and atmospheres

For products and strategies, CP aims to reduce all impacts on the environment over the entire life cycle of products, from raw material extraction to final disposal For services, cleaner production is the integration of environmental concerns in the design and delivery of services

In summary, cleaner production requires the use of know-how, technological innovation, and attitude change CP does not preclude development, but only requires

that sustainable development be ecologically and productively sustainable economy

2.1.3 Related concepts and terminology

Pollution Prevention: The two terms CP and pollution prevention (PP) are often used interchangeably They are only geographically different The term "PP" used in North America in CP is used in the rest of the world

Waste Minimization: The concept of waste minimization was introduced in

1988 by the US Environmental Protection Agency The WM focuses on recycling waste and other means to reduce waste by applying the 3P and 3R principles

Pollution Control: The fundamental difference between PC and CP is time PC

is a rear-end approach, much like late pipeline treatment, while cleaner production is a forward-looking approach that is predictive and preventative

2.1.4 Technical solutions for cleaner production

Cleaner production solutions do not just change equipment, they are also changes

in the operation and management of a business Cleaner production options can be divided into the following groups: Reduced waste at source, recirculation, product improvement

Internal Control is the simplest method of producing cleaner Good housekeeping does not require investment and can be done right after identifying the cause and finding solutions

Better Process Control to ensure optimum production conditions in terms of raw material consumption, production and waste generation The parameters of the production process such as temperature, time, pressure, pH, speed should be

Material Replacement is the replacement of materials used with other environmentally-friendly materials Changing materials may also be a better purchase

of quality materials to achieve better use Usually the amount of raw materials used, the quality of raw materials and products have a direct relationship with each other

Improving Equipment is to change the existing equipment to a lesser extent The improvement of the equipment may be to adjust the speed of the machine, to optimize the size of the storage area, to insulate the hot surface / Cool, or design

improves the necessary parts in the device

New production technology is the installation of more modern and efficient equipment This solution requires higher investment costs than other clean manufacturing solutions, which need to be carefully researched Nevertheless, the potential for saving and improving quality may be higher than other options

Raw materials circulation:

- On-site Re-acquisition and Re-use is the collection of "waste" and reuse for

the production process

- Creating By-products is the process of collecting (and treating) "waste streams" so that it can become a new product or be sold to other manufacturing facilities

and toxic chemicals used

In practice, in order to bring great effect to the application of CP production process to production, enterprises often apply various solutions in each production process (US EPA 1988)

2.2 The situation of the Implementation of cleaner production in the world and Vietnam

2.2.1 Implementation of CP in the world

In 1989, UNEP initiated the "Cleaner Production Program" to disseminate the concept of cleaner production and promote the application of the CP strategy in industry, especially in developing countries The first UNEP symposium on this subject was held in Canterbury (UK) Subsequent conferences were held every two years: in Paris (France, 1992); Warsaw (Poland, 1994); Oxford (UK, 1996); Phoenix (Korea, 1998), Montreal (Canada, 2000), Prague (Czech Republic, 2002) In 1998, the term cleaner production was formally used in UNEP's "International Declaration

on Cleaner Production"

In the world, most countries also have CP programs and on-site support for industrial enterprises In Asia, most countries have CP programs in various industries This is supported by the Government, the industry and the support from foreign organizations

Today, CP has been successfully applied in developing countries such as China, India, the Czech Republic, Tanzania, Mexico, etc., and is being recognized as a proactive, holistic approach in industrial environment management A cement plant in Indonesia by applying clean production has saved $ 35,000 a year Time to recover investment for clean production less than a year In China, experimental projects at 51 companies in 11 industries have shown that clean production has reduced pollution by

15 to 31 percent and is 5 times more effective than conventional methods (Cleaner

Production Program, 2012)

In general, cleaner production patterns in the fields of countries around the world are very rich in the industry and the efficiency is also very good Governments have developed a strategy for cleaner development, many of which provide for the

application of cleaner production in the industry

2.2.2 Implementation of Cleaner Production in Vietnam

The concept of cleaner production was introduced and tested in our country in

1995 through two internationally-funded projects: "Cleaner Production in the Paper Industry" and "Textile Waste Reduction" by UNEP in Bangkok and CIDA-IDRC (Canada) These two projects stop at the conceptual introduction level and identify the potential for waste minimization Subsequently, the concepts of ecological efficiency, pollution prevention, green energy were introduced into our country Although the designation is different, the nature of the concepts is quite similar with the purpose of

"improving the efficiency of materials and energy use and actively preventing the generation of waste at the source Produce them, minimize pollutants entering the environment On September 22, 1999, Minister of Science, Technology and Environment (formerly) Chu Tuan Nha signed the International Declaration on Cleaner Production, affirming the commitment of the Vietnamese Government to the sustainable development strategy

Over the past few years, CP activities in Vietnam have focused on:

- Disseminate information and raising awareness

- Demonstrating CP technology in enterprises to persuade the industry to take the

CP approach into production and business

- Training human resources and building international capacity on cleaner

production and building legal basis for CP promotion

* Implementation of Cleaner Production in Thai Nguyen industry

Examples of CP application in Thai Nguyen:

Paper production, cement production, metallurgy, fibroximang

For paper and pulp production: at ThaiNguyen Paper Export Joint Stock Company the products are yellow paper for export to Taiwan Raw materials of wood, bamboo, with a capacity of 6,500 tons per year, the company has a total staff 200 employees Implementation solutions include 29 measures (19 internal management, 1 improvement 2 changeable materials, 4 changeable equipment, 1 technology change, 2 revolutions and reuse

2.3 Implementation of CP to the paper industry in Vietnam

In recent years, the protection and management of the environment of Vietnam has been paid more attention and management and especially since the Prime Minister's Decree 64 was born, a series of businesses Viet Nam has serious environmental pollution issues to close A number of businesses, including paper mills, have to change their production facilities to improve the quality of the environment

According to the Vietnam Cleaner Production Center, only nine paper and pulp producers are participating in the CP program, saving about VND10 billion a year from raw materials, coal, FO oils and clean water , while the investment capital for

CP is only 3.3 billion VND with a short payback period of less than 1 year It is noteworthy that nine enterprises participating in CP production process have reduced the volume of wastewater more than 1,800,000 m3 / year, the amount of CO2 reduced

by 6,000 tons / year (Vietnam Cleaner Production Center 2009 "Cleaner Production Guideline in Paper and Pulp Industry"

The application of cleaner production in new industries is initially piloted in some basic production sectors The application of cleaner production in Vietnamese enterprises at the present time is also It is extremely difficult especially for the pulp and paper industry The difficulty of applying cleaner production in Vietnam's paper industry is not only the cost of technology transfer but also the supply of raw materials for production Most Vietnamese paper producers Raw materials used in pulp production are natural resources, with very few enterprises using recycled materials
