Feedstock recycling is one of the alternatives available for consideration, and Feedstock Recycling of Plastic Wastes looks at the conversion of plastic wastes into valuable chemicals useful as fuels or raw materials. Looking at both scientific and technical aspects of the recycling developments, this book describes the alternatives available.
Feedstock recycling—current state of the art. Feedstock recycling, also known as chemical recycling or tertiary recycling, aims to convert waste polymer into original monomers or other valuable chemicals. These products are useful as feedstock for a variety of downstream industrial processes or as transportation fuels.

Cefic definition: Feedstock recycling, also known as chemical recycling, aims to convert plastic waste into chemicals. It is a process where the chemical structure of the polymer is changed and converted into chemical building blocks including monomers that are then used again as a raw material in chemical
12 Feedstock recycling (pyrolysis and gasification) produce molecules that cannot be directly converted into polymers and need to be used as feedstock in a refining-conversion-polymerisation process. 13 Fuel production is the equivalent to energy recovery and does not contribute to creating a circular economy for plastics.
recycling costs. The alternative to separated polymer streams is to treat shredder residue containing PU with the rest of non metallic materials either directly or after refinement depending on the user. A number of feedstock recycling technologies like traditional gasification, pyrolysis and new thermal or feedstock
Feedstock recycling, also known as "chemical recycling," is the process of breaking down collected plastics into monomers and other basic chemical elements ("depolymerization"). This is an attractive option for plastic products that are difficult to recycle mechanically due to low quality, composite nature or low economic value.
Solvolysis Mechanical recycling Introduction We are eagerly anticipating the 6th International Sympo-sium on Feedstock Recycling of Polymeric Materials (ISFR), which will be held this year in Toledo, Spain, from the 5 to 7 October. More than a decade has past since the ﬁrst ISFR meeting in Sendai, Japan, in 1999 (Table 1).
Mechanical recycling is primarily a method of treating single polymer waste. The waste is converted into pellets or granules for extrusion into new products. This allows the addition of virgin polymer materials, pigments and stabilisers. Feedstock recycling is a relatively new recycling technology, which can be used to treat mixed polymer waste.
"Feedstock Recycling", a broader form of "Chemical Recycling" must be seen as an important part of the solution, it is one of the most profitable and flexible recycling solution on the market, seen from both input material (feedstock) and end products.
feedstock for recycling, highlighting waste as a feedstock for the production of fuels and chemicals. In his presentation, Dr. Abdullah focused on several organic waste streams: food waste, residuals from wastewater treatment, and manure from …

Polystyrene waste becomes valuable feedstock. Ineos Styrolution has reported the final results of the research project ResolVe. ResolVe was granted a funding from the German Federal Ministry of Education and Research (BMBF) to explore the recycling of polystyrene. The project proves the feasibility of post-consumer waste becoming a valuable ...

Feedstock recycling is one of the newer methods to recycle plastics. Sometimes also referred to as chemical recycling, feedstock recycling can be defined as attempting to recover the basic raw materials (monomers) from the plastic. These raw materials can then be reused in various chemical and industrial processes.
Feedstock recycling is a growing field in Japan, but is challenging due to the mismatch with current domestic recycling systems. However, advances in research and technical development show the potential to achieve an advanced recycling-based society. In Japan, mono- ...
Feedstock recycling is seen to be complementary to conventional mechanical recycling as it is able to treat mixed or unsorted PVC waste and recover valuable materials. However, a study showed that feedstock recycling (or at least the two that was considered) incurred higher costs than landfilling, primarily due to the low value of the recovered ...
Feedstock Recycling of Waste December 5, 2017. 3 ITC Implementation of a Circular Economy for Carbon Containing Materials Replacement of fossil carbon feedstocks by recycled materials A variety of recycling processes have been developed in the past for: Mechanical/material recycling

Feedstock recycling of scrap polymers by thermal and chemical methods is well known and environmentally accepted. The paper presents the results of thermodynamic analysis of the conversion of polyolefins in a fuel-like mixture of hydrocarbons using thermal cracking in a new type of tubular reactor with molten metal.
The first International Symposium on Feedstock Recycling of Polymeric Materials (ISFR) was hosted in 1999 in Sendai, Japan. Since then, the ISFR has been held five times in different places in ...

Feedstock recycling of polyolefins through thermal-cracking has been performed in the UK through a facility initially built by BP and in Germany by BASF. However, the latter plant was closed in 1999 (Aguado et al. 2007). Chemical recycling of PET has been more successful, as de-polymerization under milder conditions is possible.
Recycling and Recovery of Polyurethanes Austria (elastomeric foam) and Germany (RIM, SS), UK (Flexible slab stock). The role of petrochemical type feedstock recycling has been diminished to non existence. Cost effective recycling techniques for other feedstocks, such as the use of plastics in iron blast furnaces to
As feedstock recycling and pyrolysis is not incineration there are no toxic or environmentally harmful emissions. Pyrolysis recycling of mixed plastics thus has great potential for heterogenous plastic waste that cannot be economically separated. This book provides an overview of the science and technology of pyrolysis of waste plastics.
