Evaluating six economic and two environmental performance metrics for recycling of waste PET via solvent-based dissolution–precipitation processes.
Polyethylene (PE) films are one of the highest production volume plastic products, but they have very low recycling rates. A novel liquid fed pyrolysis process (LFP) is an advanced technology that can be applied to waste PE films. In this work, two environmental and six economic metrics were evaluated for LFP under different scenarios with a baseline capacity 8,400 Metric Tons (MT) products/year. The studied considered improvement such as heat integration, changing final product yields,...
The inclusion of diverse feedstock, such as herbaceous biomass is necessary to meet the rising demand for pellets in heat and power generation, biofuel production. US well positioned pioneer a uniform-format feedstock industry. This study aims develop value-added miscanthus blended with corn stover switchgrass analyze chemical, physical, mechanical properties pellets. Pure blends ratios 75:25 50:50 were considered. pellet durability index (PDI) was less than 85%, below ISO 17225-6 standard...
Many actions are underway at global, national, and local levels to increase plastics circularity. However, studies evaluating the environmental socio-economic impacts of such a transition lacking regional in United States. In this work, existing polyethylene terephthalate polyolefin supply chains Michigan were compared potential future (‘NextCycle’) scenario that looks increasing Michigan’s overall recycling rate 45%. Material flow analysis data was combined with metrics evaluate...
The motivation of this research is to evaluate the capability current turbulence models predict velocity, temperature and heat transfer rates in compressible turbulent boundary layers. challenges behind capturing both velocity variables independently are mainly due close coupling two with It a well-established fact, once Mach number exceeds 0.3, compressibility effects flow cannot be overlooked. Further, under conditions, density variations become very significant, resulting rate playing an...
A model cationic dye, m-nitrobenzylamine (NBA), was synthesized, and the diffusion adsorption behavior in polyacrylonitrile investigated by cylindrical film roll method. pKa of NBA determined spectroscopically to be 9.2 at 25 °C. The concentration dependent described chemical potential gradient model. temperature dependence coefficients above Tg, which found 65 °C from inflection point Arrhenius plot, could WLF equation, where C1g C2g are 1.64 17.09 (deg.) pH 4.2, 2.41 33.11 6.8,...
Increasing use of plastics in our everyday life has led to a global plastic waste crisis. Chemical recycling via dissolution-precipitation is promising “plastic-to-plastic” technology that enables circular economy single step. Our work compared the effects process heat integration on six economic and two environmental metrics for dissolution processes with polymer recovery three precipitation techniques. Lacking prior studies, transportation model was developed account collecting feedstock...
The sustainability of the biofuel industry depends on development a mature conversion technology national level that can take advantage economies scale: nth-plant. This study addresses logistic challenge mobilizing cellulosic feedstock supplies for sustainable bioenergy industry. A Mixed Integer Linear Programming (MILP) model was developed and updated to deliver on-spec biomass considers both desired quantity quality at biorefinery. Our supply chain analysis includes multi-modal transport...
