In recent years, the world has been committed to the development of environmental industries and sustainable resources, and continues to implement the strategic idea of the scientific concept of development to prevent environmental pollution and resource waste. However, the nation seems to be accustomed to the use of disposable items such as toothbrushes, toothpaste and slippers in hotels. With the rapid development of the hotel industry, a large number of disposable items have been used in the hotel industry for a long time, which has brought great pressure to the environment and does not meet the requirements of the concept of low-carbon economy and green development. Through the investigation and analysis of the use of disposable products in hotels, this paper explores the solution and feasibility of banning disposable products in hotels, aiming to contribute to the low carbon economy and low carbon consumption.

As an important slurry material for water-based drilling fluids, montmorillonite has been widely used in oil drilling because of its excellent properties such as expansibility, dispersion and suspension, slurry making, cation exchange and adsorption. However, at a certain temperature and pressure, montmorillonite will transform into illite, chlorite and other minerals, changing the properties of drilling fluids. In order to systematically summarize and sort out the current research status of montmorillonite transformation, this study focused on the research progress of montmorillonite transformation into other minerals under different temperature and pressure conditions, and summarized the transformation mechanism of montmorillonite. The montmorillonite is transformed into illite by adding K+ in the interlayer spacing and removing Si4+ by adding Al3+ to tetrahedron structure. The conversion of montmorillonite to chlorite by adding Fe2+, Mg2+ ions into the octahedron, and Si4+ in the tetrahedron is replaced by Al3+. The precipitated brucite layer is connected with the upper and lower layers.

The pricing of insurance products has always occupied a central position in the insurance business and has long been an important focus of academic research. With the development of theory, the combination of option theory and game theory provides a new analytical perspective for insurance pricing. Specifically, insurance can be viewed as a kind of option so that the strategies in option game theory can be applied to determine a reasonable premium level. In this context, this study aims to explore in depth how option game theory can be applied to the insurance pricing problem. First, this paper defines insurance as a special form of option and tries to borrow the classical option pricing model, i.e., the Black-Scholes model, to explore the insurance pricing problem in this new perspective. The Black-Scholes model is an important tool in the field of option pricing, through which a reasonable insurance pricing approach can be derived. Secondly, this paper further introduces the concept of game theory and constructs a basic framework of games in insurance pricing. In this framework, the interaction between insurance companies and policyholders is regarded as a game process, and the decision-making behavior of both parties directly affects the price formation of insurance. Game theory provides a new theoretical basis for understanding the pricing mechanism in the insurance market. Finally, this paper focuses on the potential application of American put options in insurance pricing based on option game theory.
