This manuscript provides an overview of the legislative requirements for use mechanical recycled plastics in articles placed on EU market, as seen from perspective a recycler. The first part reviews main principles included overarching legislation Registration, Evaluation, Authorisation and Restrictions Chemicals (REACH) to what extent these are applicable recyclers plastics. interactions betwe...

In light of the circular economy gaining momentum, plastics recycling is regarded as a key solution to keep materials in loop. Continuous efforts are needed achieve packaging waste targets set by European Union. Hence, this work evaluates potential Icelandic value chain for enhanced rates. addition identifying main challenges and opportunities, feasibility study was conducted on expansion depos...

At present, the only place in the world where experiments utilizing low-energy antiprotons can be performed is the AD at CERN. The MUSASHI trap, as part of the ASACUSA collaboration, enables access to antiproton energies of a few hundreds of eV. Whilst the MUSASHI trap enables cutting-edge research, the available beam quality and luminosity is not sufficient for collision experiments on the lev...

Abstract Expanded polystyrene (EPS) is a synthetic plastic used in various industrial and commercial applications. EPS popular for its unique physical properties, specifically insulating capabilities low density. These properties become problematic at the end of useful life as cannot be recycled with other conventional plastics. Though possible, recycling often practically or economically prohi...

The linear economic model behind contemporary product lifecycle representations contradicts planetary boundaries and the idea of sustainability. At same time, Circular Economy (CE) driven models lack consideration profound technological insights. Based on observations in research application projects different industries, a quantitative qualitative literature analysis is applied to identify bot...

This paper discusses the closed-loop supply chain which is composed of a manufacturer, a retailer and the third-party recycler, the market dominated by manufacturer. Consumer conveys different preference for new products and remanufactured products. From this base, we segment markets and determine the market demand of different products. Then, we set up a closed-loop supply chain with the third...

To provide the maximum possible cooling rate for the Recycler Electron Cooling (REC) [1], the cooling section has to be immersed into a high-quality longitudinal magnetic field. Namely, the solenoidal field of 50150 G should have an integral of the transverse component below 1 G⋅cm over the whole 20-m cooling section [2]. The transverse field components are measured by a dedicated compassbased ...

A broadband RF system has been built for the new Fermilab Recycler Ring. It is designed to both bunch and capture beam during transfers and create multiple, moveable RF barrier buckets for azimuthal control of the stored antiproton beam. Beam will be bunched and captured using bursts of four RF cycles at 2.5 MHz. To maximize bucket area, the multiple barrier buckets will be generated by pairs o...

The Fermilab Electron Cooling project involves interacting a 4.3 MeV, 0.5 A DC electron beam with 8.9 GeV/c antiprotons in the FNAL Recycler Ring. This interaction occurs through a 20-meter long cooling section consisting of 10 solenoid modules. This cooling process would lead to an increase in the Tevatron collider luminosity needed to support RunIIb parameters. There are several important eng...
