The wastes which infiltrate into the environment are created from unexpended materials and products. The environment can manage a great amount of waste, but this process requires time. Nature always attempts to achieve the balance . However, degradation of some materials in nature takes about 1000 years, which is a very long period of time in terms of the length of a human life, also in view of the rising trend of wastes generation. The need for appropriate waste management is steadily rising, as does the production of wastes and our living standards. Incorrect waste management has a negative impact on all components of the environment. Waste management, their processing and recycling additionally contribute to human health protection and preservation of a healthy environment. Another benefit is in the form of raw materials extraction, the global supplies of which are constantly reducing. One of the possible ways of effective waste management is improving environmental awareness but the science brings different ways of solution, for example in connection with waste management and simulation of wastes flow. The paper presents one of this ways by help with the creation of centralized collection point of wastes using a universal model which is usable for different countries with the problem of wastes and waste management.

The paper presents the general function, the division and the description of the main jig parts. It gives account of the basics and principles of a measuring jig structure using CAD applications. The main part delves into design of individual measurement jig options for measuring deformations of thin-walled robotic and conveyor components. Tension and stress analyses for each option have been performed. Subsequent to stress analysis, a suitable option was selected, with a description of its main parts, the production process and the necessary production equipment. Finally, the jig produced for the purpose of measuring deformation of thin-walled robotic and conveyor components is presented.
