In todays modern era, the development of industry and commerce is extremely potent, producing lots of factories, and shops ranging from large scale to micro scale. An example of the district that is known to develop in this field is East Cengkareng located in west of Jakarta.This district, this area is packed with activities, from commerce and production, ranging from big to medium to micro business. On the other hand, this district also packed by middle rank to lower rank residential, proven from the concentrated small housing despite its high-density population. The consequences of highly concentrated activities in commerce and industry is a less developed facilities and categorized as a district with the highest Environmental and health problem in Jakarta. Through observation, data collection, and interviews, the advice, and aspirations of the residents are collected and reorganized based on third place theory and nest concept producing Creation and Re-Creation Building in East Cengkareng as a building designed entirely based on the needs of the residents around to talk, relax, relieve stress, and yet remain productive. This third place encourage people to recycle and remake trash actively. Through this activity, people can increase their life’s qualities and develop their potential, socially or skillfully. This building itself is made from many kinds of trashes such as waste plastic bottles, paper scraps, wood pieces, and others that are recycled and remade into a functional and comfortable building; in other words, this building is a ‘masterpiece’ on its own built with trashes. Keywords: architecture; east cengkareng; facilities; papercraft, third place AbstrakDi era modern ini, perkembangan industri dan niaga sangatlah pesat, menghasilkan banyak pabrik-pabrik and toko-toko dari yang berskala besar hingga mikro. Salah satu contoh wilayah yang berkembang dalam bidang ini adalah Cengkareng Timur yang terletak di Jakarta. Wilayah ini memiliki aktivitas yang sangat padat, mulai dari perdagangan, produksi, mulai dari usaha besar, menengah hingga usaha mikro. Dilain sisi, wilayah ini juga padat akan pemukiman menengah dan kebawah, terlihat dari padatnya bangunan dan penduduk. Sebagai akibat dari tingginya fokus dan aktivitas masyarakat di bidang industri dan niaga, wilayah ini kekurangan fasilitas sosial dan terkategori sebagai wilayah dengan Indeks Kerawanan Lingkungan dan Kesehatan (IKLK) tertinggi se DKI-Jakarta. Melalui observasi, pengumpulan data, dan wawancara, data-data dan kebutuhan serta aspirasi masyarakat dikumpulkan dan dikelola menurut teori third place dan nest concept, sehingga menghasilkan Wadah Kreasi dan Rekreasi di Cengkareng Timur yang didesain sepenuhnya berdasarkan kebutuhan masyarakat Cengkareng Timur untuk bercengkrama, bersantai, melepas penat, dan mengisi waktu luang, namun tetap produktif. Third place ini mengajak masyarakat untuk turut aktif dalam mengolah sampah terutama sampah kertas. Melalui aktivitas ini seseorang/masyarakat dapat meningkatkan kualitas hidup dan potensi dirinya, secara sosial, maupun keterampilan. Bangunan ini sendiri dibuat dari berbagai macam sampah seperti botol bekas, kertas sisa, kayu bekas dan lain-lain yang diolah Kembali dan dibentuk menjadi sebuah bangunan yang fungsional dan nyaman, dengan kata lain bangunan ini adalah ‘mahakarya’ yang terbuat dari sampah.

<p>Plastic waste presents a real global challenge and a threat to health, environment and the global economy. While awareness of the devastating effects of plastic waste on the environment has increased, the production of plastic products is still on the rise. As a result, many countries do not prioritise waste plastic recycling or the export of plastic wastes to other countries for recycling. However, the products from recycled waste plastics are considered to be of low quality and uneconomical to produce on large scale, thus making individuals and corporations giving preference using plastics from virgin materials rather than producing products from recycled plastics. These is therefore a need to develop an effective process through the use of technology to upcycle plastic waste locally to produce products of higher value from waste plastic. The current research sought to investigate the potential of distributed upcycling to change the production and consumption of plastic products in future. To this end, the study sought to prepare high value design application for upcycling and investigated how they could be implemented through large-scale 3D printing in urban environments. To achieve this, the researcher collected plastic waste materials from Wellington in New Zealand to be used in the study experiments. The plastic waste materials were first cleaned, sorted and cut into small pieces using a granulator before being taken through thermal processes to dry them out and set the right temperatures to ensure consistency of the plastic waste extrusion before being taken through the extrusion process. 3D Printing was used to design and make various final products from the recycled plastic waste. Experimentation with different formulations of waste plastic led to production of a high-quality filament successfully achieving the study objectives. As such, upcycling plastic waste using 3D Printing technology provides a locally viable solution to making useful products in large scale as a model for future development.</p>

Dumping of waste plastic, which are non-biodegradable causes serious environmental problems. Not only do they take up huge amount of space in dumping landfills but also being a non-renewable resource, it faces depletion. Hence, it is very essential wherever possible to reduce these waste plastics means of recycling. In addition, the increasing trends of plastics in varied applications drives for more solutions for reuse of waste plastics. The existing recycling machines, which are currently in operation, are expensive and are operational only for large-scale industries. In addition, shredder and extrusion work separately but on this study shredder and extrusion are integrated to perform the given task simultaneously including mold. All section of the machine operates based on timing. This present work hence focuses on designing a plastic recycle machine for small-scale applications by incorporating an extrusion hopper mechanism. Various machines parts and assembly of hopper, shredder, extruder, heating-coil, molder, and frame are designed and analyzed using CATIA, ANSIS and FESTO. Detail analysis of the machine becomes an efficiency of 80%, having a capacity of delivering up to 20.4 kg of finished plastic blocks per hour. The working capacity of the machine ware almost three full cycle per minutes which gave the production rate of 180 products per hour


The amount of plastic waste in India is reaching a gigantic scale. Wastes from household, industries and medical facilities contribute towards this. As the plastic waste is a cause of various environmental and health hazards, its proper management that leads to an effective reuse or disposal is a concern for the Government and civic bodies. Waste plastic, when added to hot aggregates, forms a fine coat of plastic over the aggregates and such aggregates, when mixed with the binder is found to give a mix that has higher strength and resistance towards the deteriorative actions of water. Thus, (the bituminous Roads using waste plastic in the wearing course) also called as plastic roads are now gaining popularity in India. With the Indian Road Congress bringing out a code of specifications on plastic roads (IRC SP: 98 -2013), many agencies are coming forward to implement plastic roads in India as it is a sustainable method and also need of the hour. However, for a large scale implementation, the performance and longevity of these roads need to be evaluated comprehensively. This paper presents the various properties of bituminous mix with 8% waste plastic when compared with normal bituminous mix with the help of a comparative case study. In Pune, Maharashtra, India ten city roads which were overlaid with normal bituminous mix and ten roads which were overlaid by bitumen mixed with shredded waste plastic were studied for their performance over duration of two years from the time of laying of the overlays. Laboratory experiments and on- field tests were carried out to evaluate their functional and performance characteristics after they were opened to traffic. The results report an improved performance of plastic roads over the conventional ones.
