Study on the recycling of 100Cr6 powder by plasma spheroidization for Laser Powder Bed Fusion

open access: yesJournal of Materials Research and Technology, 2023
Additive Manufacturing (AM) of steel parts is crucial in various industries such as medical, energy and transport. Laser Powder Bed Fusion (L-PBF) is a commonly used technique for producing such parts, but it can alter the properties of the unconsumed powder.

Laser Powder Bed Fusion of Chromium Bronze Using Recycled Powder [PDF]

open access: yesMaterials, 2021
Laser powder bed fusion (LPBF) of Cu-0.5Cr was carried out using recycled powder taken out from the LPBF machine after previous printing. Various volumetric defects characterized the powder wherein particle size distribution was the same as virgin powder. Using recycled powder resulted in extra spherical pore formation after the LPBF process.

Recycling of used vegetable oils by powder adsorption

open access: yesWaste Management & Research: The Journal for a Sustainable Circular Economy, 2022
The treatment of used vegetable oil (UVO) with seven different adsorbents and through two different procedures (stirring and gravity filtration) was explored. Important differences in terms of density, turbidity, electrical resistance, free fatty acids (FFAs) content and relative fatty acid distribution were observed.

PA12 Powder Recycled from SLS for FDM [PDF]

open access: yesPolymers, 2019
In this study, Polyamide 12 (PA12) powder recycled after selective laser sintering (SLS) was made into filaments for fused deposition modelling (FDM). Compared with fresh PA12, the melt flow rate (MFR) of the recycled PA12 powder decreased by 77%, but the mechanical properties were only slightly reduced.

Recycling Technology of Cementitious Powder for Completely Recycling of Concrete Waste [PDF]

open access: yesJournal of the Korean Institute of Building Construction, 2005
Recently, there have been many studies seeking towards the utilization of cementitious powder from concrete waste as recycled cement. However, most of the studies actually have been researches about the reuse of mortar or paste, not concrete waste. In fact, either mortar or paste is quite different from a real concrete waste in terms of age and mixture.

Utilizing hydrolyzed powder recyclates as filler in polystyrene

open access: yesMaterialwissenschaft und Werkstofftechnik, 2019
AbstractIn the present study, hydrolyzed powder coating wastes were used as filler materials in polystyrene compounds, and the effect on the mechanical properties, melt flow index and density of polystyrene compounds were investigated. Epoxy/polyester, epoxy and polyurethane systems with thermoset structure were used as powder coating recyclates. After

Recycling Waste Fiberglass by Powder Grinding and Direct Molding of Powders

open access: yesPolymers
Direct molding is a compression molding process of thermoset particles without the addition of any linking agent or binder. It is suitable for recycling end-of-life fiberglass or other waste from the manufacturing of fiberglass products. In this study, for the first time, the feasibility of recycling waste fiberglass powder, collected from an industry,
