Circularity: Understanding the Environmental Tradeoffs of Additive Manufacturing with Waste Plastics
Publikováno v:
Recycling, Vol 9, Iss 5, p 72 (2024)
This paper examines the emissions tradeoffs of additive manufacturing (i.e., 3D printing) using plastic waste in fused granular fabrication (FGF) versus traditional fused filament fabrication (FFF) and injection molding (IM). A ‘cradle-to-gate’ l

As variable renewable energy generation in Texas increases over the next decade, flexibility and system inertia needs are likely to increase. Although natural gas peakers and combined cycle plants have met these demands in the past, grid-scale energy

This study includes thermodynamic and economic analyses of a seawater reverse osmosis (RO) plant integrated with a small-scale combined cycle natural gas (CCGT) plant ranging from 36–71 megawatts (MW). These analyses model electricity produced by t

Recent droughts and heat waves have revealed the vulnerability of some power plants to effects from higher temperature intake water for cooling. In this evaluation, we develop a methodology for predicting whether power plants are at risk of violating

This research looks at coupling desalination with renewable energy sources to create a high-value product (treated water) from two low value resources (brackish groundwater and intermittent solar energy). Desalination of brackish groundwater is alrea

This investigation studies desalination powered by wind and solar energy, including a study of a configuration using PVT solar panels. First, a water treatment was developed to estimate the power requirement for brackish groundwater reverse-osmosis (

Brackish groundwater desalination is increasingly being considered as a means to supplement drinking water in regions facing scarce freshwater supplies. Desalination is more energy intensive and expensive than traditional freshwater sources. One meth

Hydraulic fracturing, the injection of a pressurized fluid mixture of mostly water, sand and a small amount of chemicals (frac fluids), increases extraction rates and recovery of oil or gas. The technique has become increasingly popular when used in
