Abstract (sommario):
In human life, waste is a problem that will inevitably become, and will never end. This waste problem is caused by high human consumptive behavior. Plastic waste is one of the waste problems that need serious attention because the problem of plastic waste has become a global environmental problem. To be able to overcome this large plastic waste, it takes speed in absorbing plastic waste and its use in the field of processing because plastic waste is waste that is very difficult to decompose. In Indonesia, public awareness and knowledge of plastic waste are still very lacking, so that the processing of plastic waste is still not optimal. RE-Plastic Gallery is a plastic educational gallery facility that applies the plastis design method. This plastis design method takes the nature of the plastic itself, namely plastis which means it is easy to form. With this plastis nature, plastis forms, plastis spaces, and plastis activities will be applied to the design of educational galleries. People's view of plastic waste will be changed through interactive exhibition activities, ranging from exhibitions on what plastic is, the impact of plastic on the environment, plastic artworks, plastic products, to research results on plastics aimed at fighting plastic waste. That way, people who initially dispose of plastic waste will hunt for plastic waste because they are aware that plastic is useful, valuable, profitable, and also fun.Keywords: educational gallery; plastic; plastis design method AbstrakDalam kehidupan manusia di dunia, permasalahan sampah merupakan permasalahan yang pasti akan dialami, dan tidak akan pernah ada habisnya. Permasalahan sampah ini disebabkan oleh tingginya perilaku konsumtif manusia. Sampah plastik merupakan salah satu masalah sampah yang perlu mendapat perhatian yang serius karena masalah sampah plastik ini sudah menjadi masalah lingkungan skala global. Untuk dapat mengatasi sampah plastik yang besar ini, dibutuhkan kecepatan dalam menyerap sampah plastik dan pemanfaatannya dalam bidang pengolahan karena sampah plastik merupakan sampah yang sangat sulit untuk terurai. Di Indonesia, kesadaran dan pengetahuan masyarakat akan sampah plastik masih sangatlah kurang, sehingga pengolahan sampah plastik ini masih belum maksimal. RE-Plastic Gallery merupakan fasilitas galeri edukasi plastik yang menerapkan metode perancangan plastis. Metode perancangan plastis ini mengambil sifat dari plastik itu sendiri yaitu plastis yang berarti mudah untuk dibentuk. Dengan sifat plastis ini, akan diterapkan bentuk yang plastis, ruang yang plastis, dan kegiatan yang plastis pada desain galeri edukasi. Pandangan masyarakat mengenai sampah plastik akan diubah melalui kegiatan pameran yang interaktif, mulai dari pameran mengenai apa itu plastik, dampak plastik ke lingkungan, karya-karya seni plastik, produk-produk plastik, hingga hasil-hasil penelitian mengenai plastik yang bertujuan untuk memerangi sampah plastik. Dengan begitu masyarakat yang pada awalnya membuang sampah plastik akan memburu sampah plastik, karena tersadarkan bahwa plastik itu sebenarnya bermanfaat, berharga, menguntungkan, dan juga menyenangkan.

Abstract (sommario):
ABSTRAK Plastik adalah suatu produk kimia yang telah dikenal dan digunakan secara luas oleh seluruh lapisan masyarakat, baik yang bermukim di pedesaan apalagi yang tinggal di kota-kota besar. Saat ini setiap hari ketergantungan terhadap plastik semakin tinggi, namun bahayanya kurang disadari oleh masyarakat. Sesungguhnya penggunaan bahan plastik dalam konsumsi makanan tidak perlu ditakutkan, asalkan kita tahu cara menggunakannya dengan benar. Bagi masyarakat awam, cara mudah untuk menghindari bahaya plastik, yaitu dengan membedakan antara plastik untuk kemasan makanan dan untuk keperluan lainnya. Karena karakteristik peruntukannya, maka bahan baku dan proses pembuatannya pun beda, sehingga masyarakat harus faham dan memerlukan pengetahuan khsusus tentang plastik. Hasil penyampaian materi tentang plastik berdampak juga positif kepada Ibu-Ibu anggota PKK di desa Bumi Raharjo dengan pemahaman yang meningkat sangat drastis tentang penggunaan plastik untuk bahan makanan. Kata kunci : Pelatihan Pengenalan Plastik, Penggunaan Plastik, Pengelolaan Plastik ABSTRACT Plastic is a chemical product that is widely known and used by all levels of society, both those who live in rural areas and those who live in big cities. Currently, every day the dependence on plastic is getting higher, but the dangers are not realized by the public. In fact, the use of plastic materials in food consumption is nothing to be afraid of, as long as we know how to use them properly. For ordinary people, an easy way to avoid the dangers of plastic is to differentiate between plastic for food packaging and for other purposes. Due to the characteristics of the designation, the raw materials and manufacturing processes are different, so people must understand and require special knowledge about plastics. The results of the delivery of material about plastics also had a positive impact on PKK members in the village of Bumi Raharjo with a drastically increased understanding of the use of plastic for food.Keywords: Plastic Recognition Training, Plastic Use, Plastic Management

Abstract (sommario):
AbstractPlastic waste needs attention because it can cause serious problems if not managed properly. Of the various types of plastics, the most widely disposed of to the environment are Polypropylene, Polyethylene Terephthalate, and High-Density Polyethylene which are usually in the form of plastic bags and bottles. This research was conducted to make bricks made of plastic as an alternative material for infrastructure that is economical, strong, and durable, which is seen based on the compressive strength value based on its type, namely PP, PET, and HDPE plastic bricks. The compressive strength testing phase is carried out three times in each type. The selling price of plastic bricks is determined by the Markup pricing method. The process of plastic brick making includes collecting plastic waste, washing, drying, chopping, melting, and printing. Based on the research results, the plastic bricks produced from the types of PET, HDPE, and PP are in the form of blocks with a size of 19 cm x 10 cm x 6.5 cm, where the PET type brick requires 5.1 kg of waste, 3.6 kg of HDPE type, and the type of PP as much as 3 kg. The compressive strength test values for PP, PET, and HDPE plastic bricks have met the compressive strength standards based on SNI 15-2094-2000, with the highest average compressive strength test values found in PP plastic bricks of 246 kg/cm², plastic bricks HDPE type 166 kg/cm², and plastic brick type PET 98.7 kg/cm². The selling price of plastic bricks without including the purchase price of plastic as raw material for making plastic bricks (Scenario I) for PP plastic bricks costs Rp1.907,00/brick, PET types Rp3.024,00/brick, and HDPE types Rp3.464,00/brick. While the selling price of plastic bricks by entering the purchase price of plastic as raw material for making plastic bricks (Scenario II) for PP plastic bricks Rp2.867,00/brick, PET type Rp4.624,00/brick, and HDPE type Rp3.944,00/brick.Keywords: Compressive Strength, Markup Pricing, Plastic Brick.

Abstract (sommario):
Designing an injection molded plastic part requires optimizing the part with respect to various stakeholders’ needs throughout its life cycle. The conditions in which a product is operating in service are often inadequately understood or specified, resulting in wrong material selection, which in turn leads to failure when the product is used. Many aspects interrelate with the initial part design and the essential rules of each should be taken into account to ensure a well-functioning plastic product. Regardless, a part design often passes sequentially from concept development to the manufacturing phase with features that unnecessarily complicate production, add costs and weaken the intended embodiment of the product. Therefore, a checklist was developed to ensure that oversights do not happen and verify that a design fulfills the requirements set for it. The commissioning company in the project was the design office Sytyte Oy. The aim of this thesis work was to investigate the effects of design decisions on the product’s feasibility and performance in service. The study focused on the underlying reasons for failures in plastic products, failure phenomena and ways of preventing them. The project started with literature research. To support the theoretical review, a small-scale survey was conducted among operators in plastic industry in Finland to strengthen the outcome of the project. The findings from the research were compiled into a checklist. The approach into the list was adopted from the FMEA method aiming to create a stripped-down version of it. The result offers a tool for anticipating and spotting possible failures by bringing up the influences that most frequently affect the part performance. It contributes to preventing delays in processing and premature failures in service. The checklist was verified by specialist consultation to receive suggestions and requirements for improvements and to ensure its reliability.

Abstract (sommario):
The growing concern for ready mix concrete industry is the disposal of returned unused concrete. In a plastic state, the concrete is a perishable product and the disposal of any unused concrete provides a set of challenges. However, little is known about the most effective parameters for recycling of returned plastic concrete without adversely affecting its properties. The present research has conducted laboratory trials to establish an optimal process for stabilizing returned plastic concretes using set-retarding admixture called “stabilizer”. Three types of cements, widely used in construction industry in Australia, are used in this research. The first is the ordinary Portland cement (OPC), while the rest are blended cements containing 25% class F fly ash and 65% slag as partial replacement of OPC.

Abstract (sommario):
Plastic scintillators provide homeland security organisations with large area, low cost gamma-ray counters at international borders. Currently these detectors connot distinguish between the sources they detect, leading to high false alarm rates during primary screening. These alarms must be followed up by time consuming secondary screening techniques using spectroscopic detectors. Here we review current PVT scintillators and present a range of techniques that optimise their characteristics. By combining these optimisations with Symetrica's spectral deconvolution and isotope identification software, PVTdetectors were given isotope identification ability. Far from being simple gamma-ray counters, these detectors were used to successfully identify a range of complex isotopes, such as Eu-152, Ra-226 and Th-232. The resulting clarity produced by these detectros was impressive, with a measured full width at half maximum of ~5% at 662keV in deconvolved Cs-137 spectrum. Detector designs are also presented here which allow PVT detectors to identify a full range of isotopes during primary screening, potentially eradicating the need for follow up examinations.

Abstract (sommario):
AbstractIn recent decades, global plastic consumption has rapidly increased. Large quantities of plastics enter the environment in various ways, often ending up in the oceans. Plastic debris is nowadays found in any aquatic ecosystems. Due to its long durability, plastics may drift around with ocean currents for decades. Nowadays, plastic debris can be found in any aquatic ecosystem. Eventually, plastics decay into smaller fragments and sink to the seafloor. Marine mammals are affected by plastics in three major ways: They confuse large pieces of plastics with food, they become entangled in fishing nets, and they ingest smaller plastic fragments together with prey items. Here we discuss causes and solutions to these problems. We use exercises to investigate plastic debris in the environment and discuss how we all can become part of the solution through our own actions.

Abstract (sommario):
AbstractRecognising the lack of local and economically accessible facilities, technologies, and public engagement in local recycling, the chapter tackles the challenge of introducing Circular Economy to cope with plastic waste in Copenhagen. The need for circular systemic innovation and holistic production models for recycling plastics led to consider how local micro entrepreneurs, SMEs, commercial resellers and citizens can collaborate for a common, sustainable goal. The chapter presents ‘Plastic In, Plastic Out’ (PIPO), a Circular system for local sourcing, recycling and production of sustainable plastic building materials and products.

Abstract (sommario):
In modern society, plastic waste has become a serious environmental issue. The inability of most hydrocarbon based plastics to naturally decompose quickly causes concern. The material piles up in landfills, waterways, and along the side of the road. One way to combat this issue is the repurposing of the material. Plastic can be converted back into oil (called pyrolysis) and refined to produce fuels. To attempt this, a custom-built steel reactor is to be filled with waste plastic, and will be heated to the plastic’s boiling point in an inert (N2) environment. The resulting vapor will be recondensed in a specially designed heat exchanger, resulting in oil, wax, and gaseous byproducts. The oil and waxes are collected in one container, and the gases are collected in a separate container. The system will require the use of thermocouples and a feedback loop to properly control temperature. The results are expected to show a correlation between plastic type and resulting byproduct composition with Grade 1 plastics producing the most gas. In addition, faster heating rates, larger plastic particle size, and higher temperatures should increase gaseous products. This may aid in the creation of commercial/industrial sized pyrolysis systems.

Abstract (sommario):
The circular economy of recycled plastics is gradually emerging. Its objective is to reduce the production of new plastics, design products with recycled plastics according to the thermoplastic characteristics of plastics, classify, wash, dry, finely shred, and then melt and remanufacture waste plastics to reshape the appearance and function of products. In this study, consumers’ acceptance, cognition, and preference for recycled plastic products were explored based on the image these products carry. A total of 11 commercially available recycled plastic products were collected, which were respectively made of propylene (PP), high/low-density polyethylene (HDPE/LDPE), and poly (ethylene glycol-co-1,4-cyclohexanedimethanol terephthalate) (PETG), and shaped by the injection moulding machine, compressor, tablet press, and 3D printing. These adjectives were used for the survey of 100 subjects for their evaluation of recycled plastic products. The consumers’ preference for the material of the recycled plastic products is in the order of HDPE/LDPE > PETG > PP. In addition, the evaluation of those using moulds in the manufacturing process is high, which can achieve a better product image and win consumer preferences. In the sample products of this study, a recycled watch strap is made of LDPE material using the injection moulding machine.

Abstract (sommario):
Last Fall, the Federal Court declared invalid and unlawful the federal government Order that classified plastic articles as toxic under the Environmental Protection Act. The government quickly appealed the decision and the Federal Court of Appeal granted a stay motion which prevents the Federal court ruling from taking effect while the appeal is ongoing. Therefore, the Single-use Plastics Prohibition Regulations remain in force. Despite an acknowledgement that Canada must fight against plastic pollution, Canadian exports of plastic waste amounted to almost 175 thousand tonnes in 2022, hardly a stellar performance. In light of developments in recent years and the Canadian government’s commitment to the management and use of plastics, the authors draw on available data to give an accounting of Canada’s trade in plastic waste over the last 20 years and point some data gaps.

Abstract (sommario):
Today, it is impossible to imagine life without plastics due to their flexible characteristics. However, the attractive characteristics of plastic in several industries are generating another global problem: waste plastic disposal. According to the “OECD Global Plastic Outlook” published in 2022, global plastic waste production increased by more than 2.25 times between 2000 and 2019 to 353.3 million tons (MMT). However, only 9% of that plastic waste is recycled.

Abstract (sommario):
Science provides convincing evidence that greenhouse gas emissions generated across the plastics life cycle are estimated to be between 3.8 and 4.5 per cent of global greenhouse gas emissions. This is set to grow with a projected increase in primary plastic production. This report presents the synthesis of an extensive literature review of the plastics life cycle. It analyses the countries’ submissions to the UNFCCC, the Paris Agreement, and the Intergovernmental Committee on plastic pollution. It also suggests measures that co-benefit addressing plastic pollution and achieving the global climate goals. This report reveals critical gaps in the current reporting practice for accounting plastics impacts on climate under the UNFCCC and the Paris Agreement and points out the role of the international legally binding instrument on plastic pollution, including in the marine environment, (the instrument) in stemming climate change. The report argues that the development and the implementation of the plastics instrument provides a unique opportunity to strengthen global efforts in addressing climate change across the plastics life cycle, complementing the broader decarbonisation activities of the UNFCCC and the Paris Agreement. To combat climate change alongside the plastics life cycle, the primary focus must be on reducing the production of plastics and focusing on low-carbon design as well as improving waste management and remediation. Additionally, the report draws attention to the lack of internationally agreed definitions used for the assessment of the impacts of plastics on climate, which would guide research, national reporting, and policy interventions in the future.

Abstract (sommario):
Plastic pollution has become one of the major concerns in the world. Plastic waste is not biodegradable, which makes it difficult to manage waste plastic pollution. Recycling and reusing waste plastic is an effective way to manage plastic pollution. Because of the huge quantity of waste plastic released into the world, industries requiring a large amount of material, like the pavement industry, can reuse some of this mammoth volume of waste plastics. Similarly, the use of reclaimed asphalt pavement (RAP) has also become common practice to ensure sustainability. The use of recycled waste plastics and RAP in HMA mix can save material costs and conserve many pavement industries’ resources. To successfully modify HMA with RAP and waste plastic, the modified HMA should exhibit similar or better performance compared to conventional HMA. In this study, recycled waste plastic, linear low-density polyethylene (LLDPE), and RAP were added to conventional HMA, separately and together. The mechanical properties of conventional and modified HMA were examined and compared. The fatigue cracking resistance was measured with the IDEAL Cracking (IDEAL CT) test, and the Hamburg Wheel Tracking (HWT) test was conducted to investigate the rutting resistance of compacted HMA samples. The IDEAL CT test results showed that the cracking resistance was similar across plastic modified HMA and conventional HMA containing virgin aggregates. However, when 20% RAP aggregates were used in the HMA mix, the fatigue cracking resistance was found to be significantly lower in plastic modified HMA compared to conventional HMA. The rutting resistance from the HWT test at 20,000 passes was found to be similar in all conventional and modified HMA.

Abstract (sommario):
DIPLANOAGAP: Distribution of Plastics in the North Atlantic Garbage Patch Ponta Delgada (Portugal) – Malaga (Spain) 17.08. – 12.09.2019 The expedition POS 536 is part of a multi-disciplinary research initiative of GEOMAR investigating the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus will be on the vertical transfer of plastic debris from the surface and near-surface waters to the deep sea and on the processes that mediate this transport. The obtained data will help to develop quantitative models that provide information about the level of plastic pollution in the different compartments of the open ocean (surface, water column, seafloor). Furthermore, the effects of plastic debris on marine organisms in the open ocean will be assessed. The cruise will provide data about the: (1) abundance of plastic debris with a minimum size of 100 μm as well as the composition of polymer types in the water column at different depths from the sea surface to the seafloor including the sediment, (2) abundance and composition of plastic debris in organic aggregates (“marine snow”), (3) in pelagic and benthic organisms (invertebrates and fish) and in fecal pellets, (4) abundance and the identity of biofoulers (bacteria, protozoans and metazoans) on the surface of plastic debris from different water depths, (5) identification of chemical compounds (“additives”) in the plastic debris and in water samples.
