The establishment of the circular economy (CE) for plastics aims to reduce material losses and dependence on virgin materials; however, this practice does not necessarily imply reduction life-cycle impacts. In study, a CE sustainability analysis framework combining assessment (LCA) flow (MFA) was developed simultaneously evaluate impacts circularity metrics implementing different strategies production plastic packaging, using poly(ethylene terephthalate) (PET) bottles as an example. included...

Polyethylene terephthalate (PET) is a common plastic resin used to produce packaging, notably bottles. Most PET bottles are produced from fossil fuel-derived feedstocks. Bio-derived and recycling-based pathways bottles, however, could offer lower greenhouse gas (GHG) emissions than the conventional route. In this paper, we use life-cycle analysis evaluate GHG emissions, fuel consumption, water consumption of producing one bottle virgin resources, recycled plastic, biomass, considering each...

Lignocellulosic biomass offers a renewable carbon source which can be anaerobically digested to produce short-chain carboxylic acids. Here, we assess fuel properties of oxygenates accessible from catalytic upgrading these acids priori for their potential serve as diesel bioblendstocks. Ethers derived C2 and C4 are identified advantaged candidates with significantly improved ignition quality (>56% cetane number increase) reduced sooting (>86% yield index reduction) when compared commercial...

Polyethylene furanoate (PEF) is a bioplastic that can potentially replace its fossil-fuel counterpart, polyethylene terephthalate (PET), to reduce greenhouse gas (GHG) emissions. A life-cycle GHG, water, and consumption analysis conducted for potential alternative fossil-based PET resin, or PEF on kg-resin basis. assumed be produced from lignocellulosic feedstock (i.e., wheat straw) via furanics conversion reactions through three different pathways. The system boundary includes...

Abstract Under the 2022 Inflation Reduction Act, tax credits of up to $3/kgH 2 are available hydrogen producers if they generate emissions at levels below 0.45 kgCO e/kgH , spurring explore how production via electrolysis using electricity generated by nuclear power may qualify for such credits. With uranium as a primary fuel plants (NPPs) and no on‐site emissions, upstream associated with supply chains largely determine carbon intensity energy. Using GREET (Greenhouse gases, Regulated...

Technoeconomic and life-cycle analyses are presented for catalytic conversion of ethanol to fungible hydrocarbon fuel blendstocks, informed by advances in catalyst process development. Whereas prior work toward this end focused on 3-step processes featuring dehydration, oligomerization, hydrogenation, the consolidated alcohol dehydration oligomerization (CADO) approach described here results 1-step wet vapor (40 wt% water) hydrocarbons water over a metal-modified zeolite catalyst. A...

Economic and environmental favorability are vital considerations for the large-scale development deployment of sustainable fuels. Here, we have conducted economic sustainability analyses pathways producing bioblendstocks optimized improved combustion mixing-controlled compression ignition (MCCI) engines. We assessed 25 production target fuels from renewable feedstocks techno-economic analysis (TEA) life cycle (LCA) to determine which bioblendstock candidates likely be viable given a slate 19...

Non-recyclable municipal solid waste (MSW) can be used as feedstock for liquid fuel production via gasification followed by Fischer-Tropsch (FT) processes. Given the heterogeneity of MSW material composition and variation in properties, its convertibility to hydrocarbon fuels could vary widely, affecting sustainability utilizing non-recyclable production. This study evaluates life cycle greenhouse gas (GHG) emissions (carbon intensities [CIs]) FT from MSW. Key issues that greatly affect CIs...

Producing a valuable chemical product through diversion of wet wastes can simultaneously resolve the problems associated with increasing and greenhouse gas emissions from conventional production processes. In this work, we investigated life-cycle emissions, water, fossil-fuel consumption for waste-derived polylactic acids (PLA) three different waste feedstocks, namely wastewater sludge, food waste, swine manure, using Greenhouse Gases, Regulated Emissions, Energy Use in Technologies (GREET)...

To reduce emissions from combustion of fossil fuels, sustainable aviation fuels (SAFs) have the potential to decarbonize sector. Redirecting wastes conventional waste management practices and using them as cost-effective feedstocks for low-carbon can both disposal fuel combustion. One approach is upgrade wet SAF precursors, such volatile fatty acids (VFAs). In this study, novel membrane-assisted arrested methanogenesis was developed convert high-strength wastewater VFAs. Based on...

Twenty-four biomass-derived compounds and mixtures, identified based on their physical properties, which could be blended into fuels to improve spark ignition engine fuel economy, were assessed for economic, technology readiness, environmental viability. These bio-blendstocks modeled produced biochemically, thermochemically, or through hybrid processes. To carry out the assessment, 17 metrics developed each bio-blendstock was determined favorable, neutral, unfavorable. Cellulosic ethanol...
