Determination of the function of the panel furniture carbon footprint verification function
Lin Liping 1 Huang Shengyou 2 Li Junchang 3 650224; 3. The present situation of Vietnam Forestry University, Hanoi, Vietnam 156200), pointed out that the unreasonable setting of functional units is one of the main reasons why the verification results cannot be widely accepted by society. A convenient accounting method for introducing “standard products” as functional units in panel furniture was proposed. The carbon footprint of standard products represented the carbon emission level of a certain product, and the possibility of achieving friendship between products of different types and different companies was achieved. t sex.
Calculating and analyzing the carbon footprint has always been an effective way to evaluate the carbon emissions of furniture products. 1. If a furniture company wants to maintain healthy development. it cannot focus on benefits but must instead focus on a business model that emphasizes harmonious development of people and the environment. The verification of the carbon footprint of furniture products that has been carried out has generally had poor results. It has not played a role in reducing the use of literacy in enterprises and even the entire furniture industry.
1 The carbon footprint of furniture 4 Difficulty of the current investigation The current verification is basically in accordance with the internationally accepted product carbon footprint accounting standard, and has not yet established a convenient and applicable verification system for furniture products. The existing carbon footprint verification issues for furniture products mainly include the following: long evaluation cycle and high cost. Product carbon footprint verification is based on process analysis. Life cycle assessment involves a lot of tedious data collection and analysis of these data. so the evaluation cycle is long and costly. Furniture products have many types of materials and complicated processes, The same production line often produces dozens of products at the same time, which also brings great difficulties for data collection and carbon footprint allocation.
Emissions data for a single product cannot represent the company’s main product. Furniture companies have a large number of product models. The material, function, shape, and size of each product are extremely different. Under such circumstances, the carbon footprint verification result of one product cannot measure the carbon emission level of all products of the company. .
There is no comparable data on the emissions of products from different companies. The purpose of the selected functional units is to compare the carbon emission data of the products. To compare the carbon footprints, the two products must be based on the same function. However, the current verification of furniture products is not based on the same functional units. For example, some companies check a bedside table, some check a wardrobe or a desk, and some check the weight of a specific unit, making the final result incomparable. Even if you check the nightstand giant too, there are giant drawers with two drawers, some without drawers. but also with different functions.
As the results of the verification are not comparable, consumers are not able to know whether a product has the characteristics of low carbon, and the verification results of the carbon footprint verification cannot explain its own position in the industry, apart from bringing low carbon production to employees. The concept of the evening I, only willing to make a hollow slogan for product marketing.
2 Problems identified by the current panel furniture carbon footprint verification function unit 2.1 General requirements for functional units The carbon footprint assessment methods for products are mostly whether they can represent the emission levels of a class of products, and the impact of carbon emissions per model is weakened in the same series. The main material types of the products are relatively stable and the production process is close. In a certain period of time, the technical level of a company will maintain a certain degree of stability, so the processing technology of the same kind of material products will be similar. The close proximity of materials and processes allows us to select a representative product as a functional unit for verification in a product or a system, and the results of the verification to some extent represent the carbon emission levels of this type of product.
The volume of a single product is not large. In the furniture business, there are dozens of orders for a product, and as many as three or two hundred items are not large in quantity. There are unstable and uncertain data samples in the inspection. In this case, reducing the verification of product models, lengthening inspection time, and obtaining first-hand data from multiple production orders will increase the reliability of the verification results.
The product production cycle is longer and the production of different products is interleaved. Furniture companies have many production processes and complex processing conditions. In the case of large assembly line production, different products are processed at the same time. It is difficult for public energy (power, heat, water, etc.) and public materials (paint, tools, office supplies, etc.) All processes that are accurately assigned to a single product increase the uncertainty of the accounting results. As the mixed production of the main material and the processing technology are basically the same, if these different products are converted into a certain number of standard products according to certain rules, and the standard product is used as the functional unit for accounting, the whole accounting process will be more simplified.
2.3 The deficiencies of currently used functional units are insufficient for verification of single products. In mature carbon footprint verification standards, setting a product as a functional unit is the most common choice. However, the furniture production line is mostly multi-product mixed production. The equipment is also intermittent work. The actual working time of the single piece of furniture and the consumption of public materials can not obtain accurate data, making the reliability of the results lower. On the other hand, different companies choose products with different functions for accounting, and the results obtained are not comparable and lose the significance of verification.
The lack of unit quality verification. For the lack of verification of single product, some furniture companies, with reference to some weight or. Volume units of the product, set the unit weight of furniture products for the functional unit. For example, Guangdong Jiangmen Jianwei Furniture Decoration Co., Ltd. calculated that the company’s wooden furniture had a carbon footprint of 1857 grams per 1 kg of product at commercial-commercial stage. However, weight has no substantive significance for the function of a cow's furniture. Consumers purchase and use the furniture's storage function, sitting and lying function, etc. Even if the unit's carbon footprint is credible, It is impossible to compare the low carbon levels of the two products. 3 The introduction of “standard products” for the verification of carbon footprint of furniture 3.1 The verification of “standard products” for the carbon footprint of panel furniture The functional unit for verification of “standard products” is a convenient method for evaluating the carbon footprint of the panel furniture industry. There is a large number of products in a piece of furniture and it is not possible to account for all products. We can imagine that there are several "standard products" that represent several different types of products within the company, and these products are also representative of the entire furniture market. By accounting for these "standard products", companies and consumers can easily compare the carbon emissions between different companies' products.
As an example of the carbon footprint of mattresses by the Jinbeiyi Group, as the main materials of the company's various mattresses are relatively uniform and the production process is close, all products are converted into a typical one with a certain calculation method. The basic function of the mattress, the size of 1500x2000x230, as a functional unit of carbon footprint verification, the value of the carbon footprint of each functional unit product is 46.98 kg, the verification results can represent the company's emissions levels of all mattress products. If another mattress company conducts the verification in the same way, then we can visually compare the differences in carbon footprints between the two companies that have the same function of the mattress.
Standard product settings should meet the following principles: Standard product typical. The standard product process, material types, and composition ratios of various materials should be representative of the product series to which they belong, and the ratio of carbon emission sources should be similar to that of most products of the same family.
The number of standard products is as small as possible. A product cannot represent all categories of products across the company. A standard product can be selected as a functional unit from each product or series of products, but the number of standard products should be as small as possible.
The conversion of each product to a standard product should be reasonably accurate.
Since the verification result of the standard product can represent a class of products, any one of the products in this category should have a certain correspondence with the standard product. How to reasonably convert various products into standard products of a number of units is the key to this representative establishment. In general, the conversion model should be based on the number of sources within the product and the contribution of each source to the product's carbon footprint. At present, there is no consistent conversion method that needs to be studied in 1 step.
3.2 Cases of Panel Suite Furniture Carbon Footprint Verification Function Units The melamine panel furniture occupies a large share in the market. In this case, a melamine panel with a size of 550x420x450 and a front panel was selected from a panel-style furniture company in Kunming. Standard product, the functional unit of verification. This product is based on particleboard, melamine-impregnated paper veneer, with two drawers. Cabinet furniture is a typical opening of the plate furniture, other tables, a few of the Arab-Israeli as a deformation of the cabinet. The bedside table is a must-have for every suite of furniture, and the headboards of different companies are more consistent in size and function than before.
After accounting, the value of the carbon footprint of the bedside table in the commercial-commercial stage is 12.36 kg. This value can reflect to a certain extent the carbon emission level of the furniture produced by this company. If other companies use similar products as functional units for verification, they can be easily compared. We can even imagine that even if not every company produces such a bedside table, it can be stipulated that products with the same size and function, even a virtual standard product, will be accounted for. The result of the comparison is that each company's low-carbon production is very competitive. The one at a glance.
4 Conclusion The current carbon footprint verification of furniture products does not take full account of the characteristics of furniture products such as materials, production processes, sales models, and huge investment but did not get the necessary marketing promotion effect: one of the main reasons is the functional units. Do not:. formula. Production: 繁, : 算全部; Product's heavy workload is not conducive to a clear comparison of the product's carbon footprint differences. At the same time, the main materials of the same type or the same series of panel furniture products are the same, the production processes are similar, and the product carbon footprint has a certain corresponding relationship. The use of a standard product as a functional unit of accounting not only simplifies the verification work, but also facilitates the comparison of the carbon emission levels between the company's internal products and the products of different companies.
