Nguyen Thanh Hai – Deputy Dean of The Faculty of Supervisor Environment, Thai Nguyen University of Agriculture and Foresttry, VietNam. Abstract: Hoang Van Thu Paper Company is considered as one of the cradles of the paper industry in Vietnam, with a long history of development. The company has been asserting its name and position in the domestic and international market and contributing to the economic development of Thai Nguyen in particular and of Vietnam in general.
This thesis encompasses the way that the company has been making efforts to minimize the impact of pollutants, emission, transportation of solid waste and hazardous waste on the environment through the investment in the construction of waste water treatment systems. It also comprises the recycling of some waste as input materials for production by implementing the CP and bringing benefits to the economy, technology and environment. Moreover, the thesis also gives the 4 highest grades of proposed cleaner production solutions in the production process. Key-words: Cleaner production; water treatment; waste treatment; high performance; Number of pages: Date of submission: September 25,2018 Supervisor’s signature i ACKNOWLEAGEMENT First of all, I would like to thank the Hoang Van Thu Paper Joint Stock Company for providing me an amazing opportunity to conduct my internship in the company.
I sincerely thanks to PhD. Nguyen Thanh Hai for his advices and assistance, helping me to understand and completing my proposal and thesis. He also helped me a lot by spending precious time for checking my thesis report. I consider it is an honor to work with Ms Nguyen Thi Dung, environmental engineer of Hoang Van Thu Company who was particularly helpful in guiding me towards a qualitative methodology and inspiring me the whole period of my internship time.
She was always helpful, friendly and very kind with me. Without her guidance, I could not have accomplished this thesis. Finally, I would like to express my deep gratitude to my family and friends for providing me emotional, unceasing encouragement, as well as physical and financial support. I would like to thank all those other people who helped me in completing this report.
Because of my lack of knowledge, the mistakes are inevitable, I would be very grateful if I receive the comments and suggestions from teachers and others to contribute to the betterment of my report. Sincerely, Nguyen Van Hoa ii TABLE OF CONTENTS DOCUMENTATION PAGE WITH ABSTRACT. ii TABLE OF CONTENTS. iii LIST OF FIGURES.

45 vii 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. 1 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”.2 Research’s objectives - Understanding the current status of production and the application of cleaner production options at Hoang Van Thu Paper JSC.
- Evaluating the effectiveness of the company's cleaner production options. - Researching to improve and propose new Cleaner Production solutions to the company. 2 PART 2: LITERATURE REVIEW 2.1 Cleaner production review 2.1 The formation and development of cleaner production Facts show that industrial processes always cause environmental pollution due to emissions, wastewater and solid waste. emissions Material Producing Products Water process Energy Wastewater 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: Dilution & Treatment of Cleaner production Ignore dispersion pipe end Figure 2: The logical development of the response to pollution (Source: Heinz Leueuberger, 2000) 3 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 The general concept of cleaner production.
