The regulatory framework of nano-enabled products should be based on properties of the nano-emissions during the product life-cycle rather than the properties of raw materials used in the product synthesis.

Environmentally Responsible Manufacturing

In the product design process，according to the environmentally responsible manufacturing principle to carry out remanufacturing engineering design，to achieve the purpose of reducing the amount of raw materials, energy conservation and protect the environment, remanufacture is a systemic engineering to consider the product life cycle, which can prolong the life of the product, optimize product design, achieve minimum cost of product life-cycle and maximum efficiency and minimum environmental pollution ultimately.

The Impact

Based on the methods of product life cycle assessment, it is proposed to assess the environmental friendliness of the chemical plant. The LCA method represents the very systematic approach to assessing the environmental impact of production, carried out as a whole over its life cycle from the extraction and processing of raw materials to the use of individual components. It is used to systematically assess the impact of each stage of the production life cycle on the environment. Life cycle inventory analysis includes the collection of data required for the study, as well as the inventory of input (energy, water, raw materials and materials) and output (emissions into the environment, emissions, solid waste disposal, eastern water flows). a system that is a set of single processes interconnected by the flows of semi-finished products used in one or more given functions, with other productive systems and elementary flows with the environment (emissions into the atmosphere, discharges into water). Life cycle assessment (LCA) is a method that should be used to quantify the products and services of the environment carried out during its life cycle (ISO 14040 (2006)). There are several procedures approved by this methodology to support the calculation of the impact on emergencies. The methodology includes commercial software tools that are used directly or indirectly [1]. One of the goals of the LCA is to analyze the development of the production process at the station of emergency facilities. According to ISO 14040 (2006), the product life cycle assessment structure includes: 1) determining the level and scope to limit the study and select a functional unit; 2) analysis of input and output reserves of energy and materials that are important for the study of the research system; 3) life cycle impact assessment (LCIA) to classify environmental impacts; 4) phase interpretation, to test the overall popularity of the conclusion. The LCA can manage information to analyze and support the project and production decision-making process.

Geometric Tolerances

Tolerance information plays a critical role in many steps of the product life cycle. It is especially important due to the advances in Internet technologies and increasing integration requirements from industry. In this paper, geometric tolerances information in manufacturing process (IMP) is studied, and the layered conformance level of geometric tolerances is established according to ASME Y14.5-1994, STEP and DMIS. An EXPRESS-G data model of geometric tolerance information in IMP is established. The XML language is used to represent and program the geometric tolerances information in IMP.
