Embodiment 1

[0084] Reference attached figure 1 , the environmental and economic evaluation method of the straw cement composite board provided by the embodiment of the present application, which includes the following steps:

[0085] 101. Collect inventory data for the entire life cycle of straw cement composite panels;

[0086] Specifically, according to the basic technical framework of life cycle assessment proposed in IS014040-2006 and GB / T24040-2008, resource input data and pollutant output data in the entire life cycle of straw cement composite panels are collected.

[0087] Among them, the straw cement composite board is made of straw-based plant fiber as a reinforcing material, and cement is used as a cementitious material. In this embodiment, 1m 3 It is described as a functional unit, and the data in the subsequent examples are all based on 1m 3 Calculated and explained for functional units; production 1m 3 Straw cement composite board needs 0.54t of straw as raw material, assu...

Embodiment 2

[0107] On the basis of Example 1, the environmental and economic evaluation method of the straw cement composite board provided by the embodiment of the present application may also include after step 104

[0108] 105. Perform a sensitivity analysis on the preset environmental impact type, and obtain the factors that contribute to the preset environmental impact type in the entire life cycle of the straw cement composite board to reach the preset amount;

[0109] Specifically, because in the product life cycle evaluation, various factors have different influences on the evaluation results, so this embodiment refers to the attached Figure 4 , in the whole life cycle of the straw cement composite board, the main impacts on the natural environment are the greenhouse effect and the acidification effect, and then it is necessary to conduct a sensitivity analysis on the greenhouse effect and the acidification effect, that is, the preset environmental impact types are the greenhouse ...

Embodiment 3

[0114] Further, on the basis of Example 1, the environmental and economic evaluation method of the straw cement composite board provided by the embodiment of the present application also includes after step 104

[0115] 107. Construct a life cycle cost model, and calculate the cost and total cost of straw cement composite panels in each stage of the entire life cycle;

[0116] Specifically, in order to guide production and reduce costs according to the cost of input in the entire life cycle of the straw cement composite board and the cost of processing pollutant output, step 107 in this embodiment specifically includes the following steps:

[0117] 201. Construct resource input matrix A i×j and pollutant output matrix B k×j ,

[0118] Specifically, construct the resource input matrix A according to formula (3) i×j and the pollutant output matrix B k×j ,

[0119]

[0120] In the formula:

[0121] i and k are the types of resources and pollutants; j is the different lif...

Abstract

The invention discloses an environmental and economic evaluation method for a straw cement composite board, and belongs to the technical field of waste crop resource utilization. The environmental and economic evaluation method for the straw cement composite board comprises the following steps: collecting list data of the whole life cycle of the straw cement composite board; performing environmental influence classification according to the list data; calculating an environmental influence potential value according to the environmental influence classification; and normalizing the environmental influence potential value to carry out environmental influence evaluation. According to the invention, the contribution of the straw cement composite board to the environmental influence in each stage of the whole life cycle, namely the influence on the external environment, can be qualitatively, quantitatively, intuitively and effectively displayed, so that the whole production process of the straw cement composite board can be effectively guided, the influence of the straw cement composite board on the environment in the whole life cycle is pointedly reduced, on the premise that agricultural waste is effectively utilized, emission of harmful pollutants is reduced, and environmental pollution is prevented.

Description

technical field [0001] This application relates to the technical field of resource utilization of waste crops, in particular to an environmental and economical evaluation method for a straw cement composite board. Background technique [0002] In my country, the output of crop stalks is very abundant. The open-air burning of straws has seriously deteriorated the environment and aggravated air pollution. Designers then use agricultural waste such as straws to make cement-based composite panels with excellent heat insulation and sound insulation, which can achieve energy saving and environmental protection. The development of the crop straw board industry can not only alleviate the current shortage of timber supply in our country, but also alleviate the environmental pressure. [0003] However, during the entire life cycle of sheet metal production, a large amount of resources and energy will be consumed, and certain substances will be emitted, which will have an impact on the ...
