“…Just as in the production of monomers, it is also important to achieve the necessary specifications in the use of by-products. Thus, from an environmental point of view, it is certainly advantageous to consider various aspects early on in the development of a new recycling technology [45]. The selection of the best recycling routes for the respective plastic waste requires the consideration of different impact categories in the context of the life cycle assessment.…”

Plastic waste is one of the major challenges facing modern society. Against the background of climate change and finite fossil resources, the realization of a true circular economy for plastics is imperative. Mechanical recycling processes offer a short‐cut path for the recycling of clean, single material waste while they are not capable to handle mixed material or colored feeds. Complementary technologies are necessary to recover pure monomers, hydrocarbon mixtures or syngas from mixed secondary raw material to continuously close the loop in a circular plastics economy. Using the example of PET, this contribution discusses the benefit of integrating a back‐to‐monomer recycling for closing the loop aiming at a holistically approach integrating technological, ecological and economic aspects.

“…However, due to an electrically heated synthesis with high temperature sections and the complex metal catalysts, all other inputs or outputs play a minor role. Other authors [5,28,29] also conducted studies on the assessment of new technologies under consideration of apparatuses or production plants by taking up the approach described in the ILCD-Handbook in regards to the estimation of materials/masses [20] and quantify a significant proportion in various environmental impact categories.…”

For the assessment of separation technologies from an ecological and economic perspective, a case study was performed to investigate the influence of entrainment on energy and resource demand of a single apparatus and on a single production process. Taking the example of the Rectisol process, the influence of droplet entrainment on individual separation equipment as well as on the process as a whole was identified via flowsheet simulation. Based on the calculated mass and energy balances, an LCA and LCC approach was used for the quantification of the entrainment influence.

“…For example, Foeste et al and Rodrigo et al investigated cleaning technologies in the food and pharmaceutical industries. Other examples are case studies with focus on the transfer from batch to continuous production mode as presented, e.g., by Kralisch and Kreisel and Ott et al for chemical reaction technologies or Paschetag et al and Grundemann and Scholl for production technologies in the field of paints and coating.…”

The integration of innovative equipment technologies in production processes offers efficiency potentials with regards to energy and resource demand as well as investment and operating costs. For the estimation of these potentials, a sufficiently detailed database is necessary as well as the possibility to consider particular boundary conditions of the production process, infrastructure of the production site, and the overall plant design. A structured concept for the selection of suitable equipment technol-ogies and sizing rules for the design of the equipment for a desired process task are presented in this review. The combination with an appropriate modeling approach allows a holistic assessment of technically feasible solutions to quantify economic and ecological efficiency potentials of the equipment technologies. The application of this concept is demonstrated on the task of a typical heat transfer problem in the special chemicals sector.
