Reusing polymeric materials poses a global challenge. Polymer recycling is thus becoming an important issue in the current economy.

Fast-Track Notifications – simplifying waste shipments of in-out material for recycling

Europe is an open market with open borders for goods and people, but not for wastes. As soon as waste is a notifiable waste very complex procedures need to be followed resulting in the loss of a lot of time and money.

mtm plastics GmbH and mtm compact GmbH, which have been owned by the Borealis Group since 2016, have been recycling plastic waste since 1994. Today, mtm is among Europe’s technology leaders after changes in ownership and several phases of modernisation.

A System Model of the Recycling of Critical Raw Materials from Wastes and By-Products in Austria

The development of the high-technology industry plays an important role for the economic growth particularly in industrialized countries. This industry has a big demand on raw materials which are considered critical due to their economic importance and their associated supply risk (e.g., REE, gallium, germanium, PGE and tantalum). Subsumed under the collective term critical raw materials (CRMs), 14 of these materials were first defined by the Resource Initiative of the European Commission in 2010 and have been updated to 20 in 2014, since the supply with CRMs is crucial for European economies. In consequence the Austrian economic location, being part of the European economic area with a developing high-technology industry also depends in CRMs. Therefore also the Austrian Ministry for Transport, Innovation and Technology defined a specific list of materials that are critical or potentially critical for the country and the future manufacture of technological products as well.

Resource Recovery from Waste Using the Input Flexibility of Waste Gasification Technology

Nowadays, gasification of waste or biomass is becoming the great interest all over the world. Especially, gasification of municipal solid waste (MSW) has been well-researched in Japan. The development of MSW gasification technology was started in the 1970s in Japan because of oil crisis. Several technologies have been researched and developed. The Direct Melting System (DMS), which is the gasification and melting technology developed by Nippon Steel & Sumikin Engineering Co., Ltd., is one of the developed waste gasification technologies in this era. This technology was introduced for commercial use in Kamaishi City, Japan in 1979. As well as this waste technology, other gasification technologies have been developed for commercial use and installed.

Future Development of Waste Management in China According to the 13th Five-Year Plan

Municipal solid waste (MSW) known as trash or garbage consists of food waste, paper, cardboard, plastics, PET, glass, textiles, metals, wood and leather, nappies, slug, ash, etc. are arising from human and animal activities. The rapid development and urbanization of China have resulted in an increasing volume of MSW. So the problem of MSW management has become a major social problem, but one the other hand, because of their intrinsic properties, MSW are often reusable and may be considered a resource for energy recovery. The delivering quantity of household waste averages 179 million tons in China, and the amount of untreated MSW over the years has reached 7 billion tons.

How to Optimize Recycling Rates Using Waste Incineration
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
The improvement of recycling and reuse of waste is becoming more and more important and it is generally preferred compared to waste incineration. In fact, the incineration of waste is often considered the last alternative when recycling of a certain waste fraction is technically not possible or there is simply no market for the corresponding fraction of the waste. But instead of considering waste incineration as being contradictory to recycling, it may also be considered as an alternative way to achieve higher recycling rates. The main goal of waste to energy is the use of the chemical energy contained in the carbon and drogen, and transfer this into thermal energy. But all other elements contained in the waste will of course also be found in the various residue streams leaving the plant. For these residue streams there are possibilities for further treatment, enabling Separation of certain elements, improvement of the quality of a residue stream to allow re-use on the market or even potential for the preparation of a new product.

Disposal of Carbon Fiber Reinforced Polymers – Problems During Recycling and Impacts on Waste Incineration
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Carbon fiber reinforced polymers (CFRPs) are becoming increasingly more ubiquitous in our daily lives. CFRPs are composite materials, consisting of carbon fibers with high mechanical capabilities and a formative polymer matrix. The production process of carbon fibers is complex and energy intensive, thus making CFRPs more expensive than comparable metal materials. The advantage of CFRPs lies in their weight; metal materials of the same properties weight up to five times as much. This makes CFRPs especially valuable in areas, where weight and cost directly correlate, but high mechanical properties are still essential.
