The paper describes the basic problems regarding the possibility of using waste plastics and tire rubber waste as raw materials for the preparation of liquid energy carriers for transport (WtL processes) or directly to energy use in a WtE. Simultaneous measurements were performed at Thermal Analyzer STA 449 F3 Jupiter's (Netzsch). The study was conducted for waste samples of different density polyethylene, polyethylene terephthalate and rubber from waste tires. Gasification process of subjecting the sample was recorded TG and DSC curve, observing changes in mass, temperature and enthalpy. These studies were carried out in order to pre-determine the kinetics of thermal decomposition. The study, conducted in an atmosphere of argon/nitrogen (non-oxidizing atmosphere), both in terms of the changes of enthalpy and mass are summarized in the respective charts.
Sustainable economic and industrial growth requires safe, sustainable resources of energy. For the future rearrangement of a sustainable economy to biological raw materials, completely new approaches in research and development, production, and economy are necessary. The biofuels produced from the renewable resources could help to minimize the fossil fuel burning and CO2 production. Biofuels produced from biomass such as plants or organic waste could help to reduce both the world's dependence on oil and CO2 production. These biofuels have the potential to cut CO2 emission because the plants they are made from use CO2 as they grow. Biofuels and bio products produced from plant biomass would mitigate global warming. The 'first-generation' biofuels appear unsustainable because of the potential stress that their production places on food commodities. For organic chemicals and materials these needs to follow a biorefinery model under environmentally sustainable conditions. Where these operate at present, their product range is largely limited to simple materials (i.e. cellulose, ethanol, and biofuels). Second generation biorefineries need to build on the need for sustainable chemical products through modern and proven green chemical technologies such as bioprocessing including pyrolysis, Fisher Tropsch, and other catalytic processes in order to make more complex molecules and materials on which a future sustainable society will be based. The article presents the basic processes of converting liquid and gaseous biofuels and second-generation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
