Today, renewable bioenergy is regarded as one of the ways to supply energy at the expense of fossil fuels. The possibility of obtaining energy from organic materials through bio-electrochemical systems has attracted considerable interest. Green waste consists of organic plant-based materials generated from grass clippings, broken branches, fallen trees, and others, whose utilization is currently not very effective. In this study, we constructed a depot based on bio-electrochemical systems for the utilization of green waste with cogeneration of energy. The facility demonstrated good performance in terms of both the degradation of organic matter and the energy produced.

Microbial fuel cells (MFCs) have significant potential for sustainable energy production and waste management, but despite this, they are still not widely commercialized due to several main reasons, such as relatively low power generation, technical challenges, scalability, and others. In the present study, we tested the possibilities for storage and utilization of energy from our developed green waste composter with cogeneration of energy. The composter consists of 24 stacked solid phase microbial fuel cells. The generated energy was increased through a voltage boost converter and used for charging batteries, power banks, and low-energy consumption devices. The composter demonstrated stable operation, and the obtained results regarding the storage and utilization of the energy generated by it are promising for its commercialization.

The article presents the process of blowing out PET bottles. PET is processed for various applications due to its very good physical properties. In the packaging industry it is used for the production of PET bottles. The concepts of Blow molding is a process used to produce hollow objects from thermoplastic. The basic blow molding process has two fundamental phases. The first phase of the device’s operation consists in heating preforms. The second phase consists in the mechanical extension of the preforms on the axes and on the extension by means of pre-blowing and then blowing the preforms. The discussion was prepared on the basis of the collected literature data.

The current report aims to provide insight into the different innovative solutions in waste processing. It outlines that the new technologies for solving the waste issue should be consistent with the current requirements for saving resources and minimizing the waste going to landfills. First, the paper discusses that one of the most serious challenges of the modern world is linked to the daily disposal of hundreds tonnes of waste. They are not only a national, but a global problem, the uncontrolled disposal and accumulation can cause serious pollution of the environment and lead to worsening health. That is why the issue of their effective management is of utmost importance. The report gives special attention to the global problem with waste collection and disposal that imposes an urgent need for innovations. Next, different innovative solutions in waste processing are also analyzed in the paper. A new, better model of waste management needs to be created and innovative methods (instruments) for disposal and treatment of municipal solid waste are needed. The author identifies that scientific progress allows for the implementation of new waste management technologies such as radio-frequency identification (RFID), GPS systems, underground waste treatment facilities, multistage waste recycling system, etc. Finally, on the basis of the analysis, recommendations for waste management on a global level are outlined. A conclusion is made that when choosing a new and effective waste management technology, the ecological (safety and ecological risks) and economic (efficiency, capital and operational expenses) factors should be considered.
