Introduction

Use of recycled material is increasing in response to heightened environmental awareness. In the automotive industry, bumpers are produced by reusing recovered plastics, and in the electrical and electronics industry, smartphones are manufactured using recycled aluminum. Against the backdrop of increasing use of recycled materials, each country has established a legal and regulatory system. For example, in 2021, the German government amended the German Packaging Law (VerpackG), and required that the percentage of recycled plastics in disposable PET bottles be at least 25% from January 1, 2025. On the other hand, quality control is critical when manufacturing recycled products because raw materials with various unknown origins are used. Since there is also a risk of contamination with toxic elements such as lead and mercury, it is important to confirm that products conform to RoHS/ELV and other regulations. This article introduces examples of screening analysis for toxic elements and elemental analysis by qualitative and quantitative analysis for various recycled materials, including plastics, rubbers and glasses.
