Recyclable construction

from Wikipedia, the free encyclopedia

In the case of recycling-friendly construction ( design for recycling ), later disposal or, better still, later recycling is considered before a product is manufactured and used . The suitability of a product for later recycling is largely determined by the designer . This suitability includes the reuse or further use of the product ( product recycling ) and / or the reuse or further use of its material components ( material recycling ). In this way, technical and moral longevity as well as the dismantling and material compatibility of the product are to be striven for in the construction process.

history

At the end of the 1970s, the concept of recycling-friendly construction was introduced by Prof. Dr. Walter Jorden coined. At the beginning of the eighties, the first engineering papers on recycling-friendly product design were published. Since then, this area has gained more and more attention and acceptance. An important development was the VDI guideline 2243 (designing recyclable technical products) from 1991. In the mid-1990s, the legislature also took up the topic. Legislative initiatives such as the Packaging Ordinance , the Electronic Scrap Ordinance and the superordinate recycling and waste law mean that more and more products are designed to be recyclable.

conditions

The goal of recycling-friendly construction is to ensure the best possible product and material recycling for the product to be created.

The basic requirement for product recycling, ie the reuse of the product, is its technical and moral longevity. This is based in particular on good reparability and regenerability. Every long-lasting, functional product must also be able to adapt to technical, technological and design developments in order to counteract “moral wear and tear”. The three requirements for the construction process are durability construction , refurbishment construction and adaptation construction .

The aim of material recycling is not to recover valuable materials with undefined properties, but in a standardized quality that enables them to be reused as a material. This means that the dismantling and material compatibility of the product must be ensured in the design process.

The dismantling of a product can be achieved through an adapted building structure and dismantling and solvability.

The material compatibility of a product is characterized by minimizing the use of materials, separation and compatibility, multiple reusability and simple disposal of the materials as well as their clear identification.

VDI guideline 2243

The VDI guideline 2243 (recycling-oriented product development) provides the designer with a set of rules that makes it easier for him to design technical products in a way that is suitable for recycling and thus contributes to more recyclable products. The original name of the VDI guideline from 1991 was Constructing recycling-friendly technical products , with the revised edition from July 2002 it was called recycling-oriented product development .
