Carbon footprint verification is crucial for the sustainable development of companies, as it not only helps businesses evaluate their carbon footprint but also promotes reduced energy consumption, improved efficiency, and a positive market image. Amid the global trend toward carbon neutrality, carbon footprint verification has become essential in implementing Environment, Social, and Governance (ESG) policies for companies and organizations. Honway focuses on physical polishing technologies and has rich experience in super-hard abrasives and rare-earth raw materials, dedicated to providing low-pollution polishing solutions to meet customers’ needs for environmental sustainability and high performance.

This chapter introduces ESG (Environmental, Social, and Governance) as an essential evaluation framework for sustainable corporate development. ESG helps companies enhance their sustainable competitiveness by focusing on environmental protection, social responsibility, and corporate governance. By analyzing the differences between CSR and SDGs, a deeper understanding is gained of how companies assess projects and directions. Through the implementation of ESG, companies can not only meet compliance requirements and improve their reputation but also build stronger resilience and trust, creating long-term value for stakeholders. Against a backdrop of increasing global focus on sustainable development, ESG has become an essential indicator for successful and responsible corporate operations.

As technology advances, the application of various metals across industries has become increasingly diversified. Metallographic material science analysis (commonly known as metallography) has become crucial. Effective metallographic research can significantly enhance product quality and reduce process costs. In this article, we’ll guide you through the complete metallographic research process and share some key points. Among them, grinding and polishing are vital steps in achieving good metallographic results!

In the field of polishing, different metals require specific processing steps and tool selections. This chapter focuses on stainless steel, where the primary goals are to enhance its appearance, smooth the surface, and improve corrosion resistance. Through mirror polishing, imperfections and irregularities on stainless steel surfaces can be removed, resulting in a smooth and glossy finish. This not only improves aesthetics but also enhances the material’s cleanliness and resistance to contamination.
Proper polishing techniques can prevent surface scratches and damage while protecting the stainless steel’s oxide layer, which is crucial for maintaining its corrosion resistance. However, improper handling may cause surface damage, leading to localized corrosion or poor appearance.
The latter part of this chapter includes an experiment on mechanical polishing of stainless steel, providing insights into tool selection, the polishing process, and potential challenges. Readers will gain a deeper understanding of stainless steel’s properties and be able to choose appropriate polishing methods and tools to enhance polishing quality and efficiency.

This chapter introduces zinc metal, highlighting its properties such as malleability, wear resistance, and corrosion resistance. Common issues in polishing, such as scratches and pitting, can affect the difficulty and cost of processing. In the latter part of the chapter, mechanical polishing experiments on zinc are discussed, covering tool selection, processing methods, and problems encountered. This provides readers with a deeper understanding of zinc’s characteristics and how to choose the right polishing tools and techniques to improve polishing quality and efficiency.
