along with the rapid development of commercial concrete industry and the continuous growth of concrete demand, the commercial concrete production has brought large energy consumption and mineral resource consumption; cement calcination and direct/indirect energy consumption within the boundary of ready-mixed concrete system have become the main source of concrete greenhouse gas. This paper mainly settles key problems such as boundary definition, data collection, calculation model, data acceptance/rejection and data calculation method concerned with concrete carbon emission calculation, establishes the national uniform concrete carbon emission calculation method and emission factor within the same cultural boundary, and provides theoretical and data calculation basis for determining the reference value and grade of concrete carbon emission. As for other products, the carbon emission of unit product may also be calculated by reference to this paper; therefore, inherent carbon emission data of buildings are accumulated, providing quantized data support for taking measures to reduce the carbon emission intensity.

Because of its antibacterial properties, wormwood can be used in the production of nanobiomaterials. In this paper, each stage of the production process of wormwood viscose fiber and flax fiber was determined. The carbon emission of each stage of the production process of 1 ton wormwood viscose fiber and flax fiber was analyzed by GaBi software, and the environmental impact of the production process was evaluated by using the CML2001 method provided by the software. The results showed that a total of 1690.04 kg of carbon dioxide was emitted in the production of 1 ton of wormwood viscose fiber, 60% in the preparation stage, 36.36% in the acid bath stage and 3.64% in the treatment stage. A total of 1541.41 kg of carbon dioxide was emitted in the production of 1 ton of flax fiber, with the pretreatment stage accounting for 39.95% of the total amount, the alkali cooking stage accounting for 50.06% of the total amount, and the pickling stage accounting for 9.99% of the total amount. The results can provide support for the production of antibacterial nanofibers.

Ceramic Density

In this paper authors overviewed the most important stages of ceramics production process which give significant influence on final properties of product. Often density and porosity on the all producing stages determines exploitation ceramics properties. A calculation method for fractions ratio selection which provides optimal density is suggested here. Also, density changes during operations of grinding, forming, thermal treatment and sintering a row of specimens are researched and analysed. The data received allow to predict semi products size behaviour while producing and get definite final part with dimension required.

Gas Emissions

At present, the massive emissions of carbon dioxide and nitrogen oxides and other greenhouse gases caused by human activities have caused more and more serious negative effects on global climate change. In order to cope with global warming and achieve sustainable development, achieve “carbon neutrality” as soon as possible. In the refrigeration industry, it is necessary to reduce greenhouse gas emissions related to refrigerants, including the production, use, and recycling of refrigerants. This paper has carried out the calculation of greenhouse gas emissions during the refrigerant preparation process, and compared and analyzed the emission reductions of refrigerant recycling and reuse; the research based on the energy consumption of the refrigerant production process uses the greenhouse gas emission inventory analysis method to Taking refrigerant R134a as an example, the carbon emission accounting boundary of the production process is set, the emission source is determined, the emission is calculated based on the emission factor method, and the emission inventory is established; the carbon offset effect of the recycling and reuse of the refrigerant is analyzed. The research results show that if the entire refrigerant industry fully recycles waste refrigerants, it can reduce carbon emissions by about 29.7% compared to just producing new refrigerants.

Production Prices

Business (company) is an organization that provides a variety of goods or services for sale with the aim of obtaining profits. Accounting calculations on companies are needed at the production price and selling price at a company. In this case then direct this research in the calculation of production prices and selling prices. The data needed in this study can be obtained through documentation and field research. The data obtained in this analysis uses the Descriptive Quantitative method, based on the analysis shows that the calculation of production costs and selling prices using the calculation method carried out by the UD with the calculation of production costs using the variable costing method is lower than the calculations made by the company. Because the variable costing method calculates the variable costs associated with the production process and selling prices while the calculation method applied by the company lists all costs including variable overhead costs and fixed overhead costs. So that there is a difference in production costs and selling prices according to company methods and variable costing methods.
