The environmental impact associated with olefin production is generally determined by feedstock and energy supply as well as the production technology. In the present study, the environmental effects of the utilization of conventional and alternative feedstock are assessed in the form of a cradle-to-gate life cycle assessment performed in GaBi LCA software. The assessment focused on global warming potential, fossil resource depletion and acidification potential of olefin production in Germany. Investigated raw materials included fossil resources in crude oil and shale gas, renewable resources in wood and maize-based biogas as well as secondary resources in municipal solid waste and flue gas-based carbon dioxide. Life cycle inventory data for olefin production are obtained by process simulation using Aspen Plus. Technologically, syngas-based olefin production is characterized by a lower product carbon recovery compared to direct cracker-based olefin production. By integrating upstream impacts, renewable-based production is observed to lead to negative effective greenhouse gas emissions and low resource demand, but showed significant acidification potential from agricultural feedstock production. Due to the avoidance of waste incineration, olefin production via waste gasification is associated with significant benefits in terms of greenhouse gas emissions, despite the substitution of waste-based electricity generation with other energy sources. The utilization of carbon dioxide from flue gas displayed the highest electricity demand by means of hydrogen generation.

This article presents a concept to support the transformation from a linear 'one-way cradle to grave manufacturing model' toward a circular carbon economy. The development of new and sustainable value chains through the utilization of coal and waste as alternative raw materials for the chemical industry via a coupling of the energy, chemical and waste management sectors offers a viable and future-oriented perspective for closing the carbon cycle. Further benefits also include a lowering of the carbon footprint and increasing resource efficiency and conservation of primary carbon resources. In addition, technological innovations and developments that are necessary to support a successful sector coupling will be identified. To illustrate our concept, a case analysis of domestic coal and waste as alternative feedstock to imported crude oil for chemical production in Germany will be presented.

A technology overview of coal gasification technologies provided insights into different types of gasification processes as well as a comparative evaluation of their advantages and disadvantages. Similarly, a review of FT technologies enabled a comparative technology overview of commercial FT reactors and associated processes, their advantages and disadvantages. Using a case study approach, the suitability of identified commercial gasification and FT technologies are evaluated based on their applicability for the conversion of high ash-containing Vietnamese anthracite with high melting temperature to produce FT-diesel. Evaluation results indicated that the Fixed Bed Dry Ash (FBDA) gasification technology in combination with the medium-temperature Fischer Tropsch (MTFT) synthesis would be the most advantageous technologies for the production of FT-diesel from Vietnamese anthracite.

The utilized approach facilitates a prospective comparative assessment of feedstock recycling, conventional and PTX-based production routes under uniform system frameworks, accounting for differences in production characteristics (e.g. product yields and utility demands) with minimized allocation assumptions. An evaluation of the global warming potential shows that under assumptions resembling the current production system (Framework Status Quo), feedstock recycling pathways lead to a reduction in greenhouse gas emissions, with gasification exhibiting higher emission reduction than pyrolysis. Under the assumption that limited renewable energy is available for system emission reduction (Framework Energy Integration), a higher greenhouse gas reduction is observed for feedstock recycling compared to PTX-based chemical production pathways.}, language = {en} } @misc{LeeSeidlHuangetal., author = {Lee, Roh Pin and Seidl, Ludwig Georg and Huang, Qiu-liang and Meyer, Bernd}, title = {An analysis of waste gasification and its contribution to China's transition towards carbon neutrality and zero waste cities}, series = {Journal of Fuel Chemistry and Technology}, volume = {49}, journal = {Journal of Fuel Chemistry and Technology}, number = {8}, issn = {1872-5813}, doi = {10.1016/S1872-5813(21)60093-2}, pages = {1057 -- 1076}, abstract = {Waste gasification has the potential to contribute to China's transition towards carbon neutrality and zero waste cities via the recirculation of waste as secondary carbon feedstock for the production of chemicals with lower/and or zero carbon footprint, green hydrogen with zero carbon footprint and CO2-neutral synthetic liquid fuels.
