The work carried out focuses on the importance and characteristics of bioplastics, which is why the bibliographic sources consulted recall that the plastic manufactured from biopolymers has been increasing due to its practicality and in supporting the reduction of pollution of solid waste worldwide. Viable alternatives are currently being sought to replace packaging and coatings made from non-renewable raw materials, as these cause millions of tons of waste each year, damaging the environment. The production process of biodegradable plastics has a certain resemblance to the production of conventional plastics, it consists of a mixer of raw materials with additional components, for a subsequent blowing and sealing, passing through a quality control. One of the problems with conventional plastics is that they are manufactured from raw materials obtained from non-renewable resources, which each day becomes scarcer and therefore more expensive. Also the problem of persistence in the medium for very long times, which cause them to occupy space in sanitary landfills, which are causing problems in the country due to lack of space.

Recycling is the inclusion of wastes that can be recycled into the production process by transforming them into secondary raw materials after various physical and/or chemical processes. The natural resources are not infinite. Of course it will run out one day. For this reason, the recycling process has gained a serious dimension for countries due to both economic and environmental factors. Although the recycling process of thermoplastic materials is known and frequently used by the science and industry community, the recycling of rubber materials has remained in the background. However, with the increase in the number of automobiles around the world, the increasing amount of solid waste tires puts the society in trouble both economically and environmentally. In this research, there are data on the introduction of automobile tires, which are a very serious waste throughout the country, to the economy.

The development of polymers obtained from renewable raw materials is important because it is known that the fossil sources will be depleted in the future. Due to this fact, the possibilities for the synthesis of polyurethanes based on renewable resources increases. This work analyzes the properties of polyurethane materials obtained from the renewable resources. Polyurethane elastomers were prepared by a two stage process in solution, which involved the synthesis of the pre-polymer and synthesis of the polyurethane elastomer. As a polyol component, poly (propylene glycol) was used. Isophorone-diisocyanate and hexamethylene diisocyanate were employed as isocyanate components. For some samples, petrochemically obtained chain extender, butanediol, was replaced by biobased product isosorbide. Characterization of polyurethane materials was carried out by infrared spectroscopy with Fourier transformation, thermogravimetric analysis and differential scanning calorimetry. The properties of synthesized polyurethane materials were improved by adding the nanoparticles in various proportions.

Background: To produce homeopathic medicines, pharmacies need raw materials (mother tinctures and diluted-agitated solutions, named “matrices”), provided by insumes suppliers. The “matrices” are ultra high dilutions and can not be tested against Analysis Reports. Aims: to propose alternatives to the matrices Analysis Report; to contribute to the quality of homeopathic medicines and treatment. Method: search of information present in the documentation provided from 2 national and 3 European suppliers in order to develop criteria. Discussion: the needed concepts for compliance with the orders throughout their production process were presented. The control of information involved in the process allows to trace the production of matrices, providing an indication of the quality with which they were obtained. Each supplier gives different approach to issuing a document, calling it Certificate of Conformity Protocol Preparation, Manufacturing Certificate or Quality Certificate. Summarizing, it is a supplier's declaration, which involves the quality control of raw materials, packaging materials and of the process used, but not a report that enables customers to repeat the analysis. A model was proposed for a Certificate of Quality, with the minimum information needed to indicate to the pharmacies that there is a control of the process. This certificate shall contain statements about the process. Conclusion: Quality Certificate seems to be the best document to ensure the pharmacy that the matrix obtained presents characteristics compatible with the preparation of a quality homeopathic medicine.
