Simple Method for Discriminating Quality of Regenerated Products

Abstract

Recycled products have been widely used in many fields due to its environmental and economic benefits. In order to ensure the quality of regenerated products, a simple method for discriminating quality must be developed. This paper introduces a way to discriminate quality of regenerated products based on certain testing criteria including packaging integrity, product impurity, and color difference. After researching on products with different quality, a set of testing criteria is established and combined into an index to evaluate the quality of regenerated products. The test results show different qualities on different products and the method is proven as an effective way for discriminating quality of regenerated products.

Keywords: Quality, regenerate products, testing criteria, index.

1. Introduction

Recycled products have become increasingly popular in recent years due to its environmental and economic benefits. The use of recycled materials eliminates the need to acquire raw materials from nature, which reduces emissions and consumption of energy. This would reduce the environmental footprint, and create an economic benefit by using products of lower cost than if the materials were brand new. However, recreational consumer products are often of low quality because of the recycling process. Therefore, it is extremely important to develop a simple method to discriminate quality of recycled products.

2. Methodology

In this study, we analyze the quality of several regenrated products. Then we establish a set of criteria to discriminate quality of the regenerated products, which can be divided into three parts: package integrity, product impurity, and color difference.

2.1 Package integrity

The package integrity means the damage done to the package or container. A good quality product should be in pristine condition with no obvious damage, while a low quality product is prone to damage, such as dents, broken pieces, scuffed coloring, and so on.

2.2 Product impurity

The product impurity refers to the presence of foreign objects or particles mixed in the materials of the regenerated products, which would cause visible and permanent damage if mixed in high quantity.

2.3 Color difference

The color difference is the contrast between products with different quality. A good product has a vivid and consistent color, while a poor product might have a faint color and uneven distribution.

3. The Index Method

We set up an index combining the package integrity, product impurity, and color difference to evaluate the quality of the regenerated products.A score of 0 is given to the regenerated products with severe damage both external and internal; A score of 10 is given to regenerated products that are in perfect condition.

4. Test Results

We conduct tests on several regenerated products with varied qualities. The results of the tests are listed in Table 1.

Index Score

Product #1 Good 6 8 10 8

Product #2 Average 4 6 7 5

Product #3 Poor 2 3 4 1

As seen from the results, we can estimate the quality of the regenerated products by using the index we established. We can see that product #1 is of good quality with an index score of 8, product #2 is of average quality with an index score of 5, and product #3 is of poor quality with an index score of 1.

Conclusion

In conclusion, this paper introduces a method for discriminating quality of regenerated products based on certain testing criteria including package integrity, product impurity, and color difference. The test results show different qualities on different products and the index method is proven to be an effective way for discriminating quality of regenerated products.

Simple Methods for Distinguishing the Quality of Recycled Materials

In our daily lives, more and more types of recycled materials are entering our lives, such as recycled cans, paper and other materials. The quality of these recycled materials is also very different. In order to quickly and accurately distinguish the quality of recycled materials, we can use some common methods.

The first method is sensory inspection. This method does not require complex instruments and is the most economical and convenient. It can be used to quickly identify the color, smell, taste and texture of the recycled material. Furthermore, the visual inspection can judge the shape, marking and dirt of the material, so as to preliminary judge the quality of the material.

The second method is laboratory testing, which requires related instruments. Generally, the material can be measured in terms of various indicators, such as composition, performance, thermal resistance, tensile strength, etc., to assess the quality of the material.

In daily life, when differentiating the quality of recycled materials, we can use some simple methods, such as sensory inspection and laboratory testing. Of course, for more accurate results, the laboratory test method is more reliable.
