AbstractGlobal plastic waste generation is about 300 million metric tons annually and poses crucial health and environmental problems. Africa is the second most polluted continent in the world, with over 500 shipping containers of waste being imported every month. The US Environmental Protection Agency (EPA) report suggests that about 75% of this plastic waste ends up in landfills. However, landfills management is associated with high environmental costs and loss of energy. In addition, landfill leachates end up in water bodies, are very detrimental to human health, and poison marine ecosystems. Therefore, it is imperative to explore eco-friendly techniques to transform plastic waste into valuable products in a sustainable environment. The trade-offs of using plastic waste for road construction and as a component in cementitious composites are discussed. The challenges and benefits of producing liquid fuels from plastic waste are also addressed. The recycling of plastic waste to liquid end-products was found to be a sustainable way of helping the environment with beneficial economic impact.

In response to international trends regarding the reduction in plastic waste (or plastic pollution), this work used the official statistics that were recently released, focusing on regulatory actions restricting the use of plastic products and/or the increase in recycling in Taiwan. In addition, the impacts of the COVID-19 pandemic on plastic waste generation and plastic products’ recycling were also addressed in the present study. The results showed that the plastic compositions in the garbage slightly increased in recent years, suggesting that the effect of restrictions on the use of plastic products in Taiwan was not significant, even though the regulatory measures have been implemented since 2002. However, chlorine contents in the garbage were significantly increased in 2020. The increase could be attributed to the fact that kitchen waste (containing salt), household waste containing disinfectant (e.g., chlorine dioxide, sodium hypochlorite) or PVC-made products were generated more during the COVID-19 pandemic. Furthermore, the data also indicated that the monthly quantities of recycled plastic containers and other plastic products had no significant change since January 2020, especially in the outbreak period from May 2021 to July 2021.

Konsep pengelolaan sampah telah lama berubah dari pemusnahan atau pembuangan menjadi pemanfaatan. Namun konsep ini belum diikuti dengan langkah nyata oleh pemerintah. Kepedulian terhadap kelestarian lingkungan telah mendorong beberapa kelompok masyarakat, lembaga atau institusi untuk bergerak aktif dalam pemanfaatan sampah. Universitas Andalas sebagai lembaga pendidikan tinggi terkemuka di Pulau Sumatera sudah saatnya mengambil peran aktif dalam melakukan pengelolaan sampah yang berwawasan lingkungan. Timbulan sampah yang cukup besar yaitu 28 m3/hari pada tahun 2012, yang diproyeksikan akan menjadi 34 m3/hari atau 9 ton/hari pada tahun 2017, menawarkan potensi cukup besar untuk dimanfaatkan. Pada tahun proyeksi 2017 dari total timbulan sampah, 26,6 % (2,4 ton/h) adalah sampah makanan, 9,8 % (0,9 ton/h) adalah sampah penyapuan taman/jalan, 30,0 % (2,7 ton/h) adalah sampah plastik, 25,3 % (2,3 ton/h) adalah sampah kertas, 1,5 % (0,1 ton/h) adalah sampah kaleng, logam dan besi dan 6,9 % (0,6 ton/h) adalah sampah lain-lain (tekstil, karet, kayu, kaca dll). Dari total sampah makanan dan penyapuan halaman/jalan, 33,7 % berpotensi untuk menghasilkan kompos sekitar 1,2 ton/hari, 2,1 % (0,2 ton/h) dapat dimanfaatkan untuk proses biogas dan sisanya 0,5 % (0,05 ton/h) ditimbun di TPA. Sampah plastik dan kertas sebesar 55,3 % dapat dimanfaatkan kembali atau dijual ke PT. Semen Padang sebagai tambahan bahan bakar unit kiln. Dari 1,5 % sampah kaleng, logam dan besi, 1,3 % dapat dimanfaatkan kembali atau dijual ke pihak ketiga sedangkan sisanya yang hanya sebesar 0,02 ton/h dibuang ke TPA Air Dingin. Selanjutnya, sisa timbulan sampah sebesar 6,9 % yang berupa sampah tekstil, karet, kayu, kaca dan lain-lain dapat dimanfaatkan sebagai bahan bakar alternatif pada kiln PT. Semen Padang. Jika konsep ini dapat dilaksanakan, maka Universitas Andalas dianggap mampu melakukan pemanfaatan sampah hingga 99,3 %. Kata kunci: Pemanfaatan sampah, kelestarian lingkungan, pengelolaan sampah yang berwawasan lingkunganABSTRACTManagement of solid waste has been changed from dumping to utilization. However, this concept is not fully applied yet by the government. Environmental sustainability awareness has been stimulating some community groups and institutions to actively involve in waste utilization. Andalas University as a leading higher education institution in Sumatera Island must give active contributions in solid waste management for environmental sustainability. Solid waste generation of 28 m3/day, which is projected to be 34 m3/day or 9 ton/day in 2017, offers huge enough potency for utilization. From the total solid waste generation in 2017, 26.6 % (2.4 ton/day) is food waste, 9.8 % (0.9 ton/day) is garden/road waste, 30.0 % (2.7 ton/day) is plastic waste, 25.3 % (2.3 ton/day) is paper waste, 1.5 % (0.1 ton/day) can, metal and iron waste and 6.9 % (0.6 ton/day) is micellaneous waste (textile, rubber, wood, glass etc). 33.7 % of food waste and garden/road waste may be recycled to compost around 1.2 ton/day, 2.1 % (0.2 ton/day) may be utilized for biogas and the rest 0.5 % (0.05 ton/day) is sent to TPA Air Dingin. Plastic waste and paper wich is 55.5 %, may be used for additional fuel for kiln unit of PT. Semen Padang. From 1.5 % can, metal and iron waste, 1.3 % may be reused or sold to third party while the reset (only 0.02 ton/day) must be disposed to TPA Air Dingin. Furthermore, the rest of waste generation account for 6.9 % composed of textile, rubber, kayu, kaca dll may be used as alternative fuel for kiln PT.Semen Padang. If this concept is practiced, then the Andalas University is considered capable of utilizing their waste up to 99.3 %.Keyword: Utilization solid waste, environmental sustainability, management of solid waste

Plastic waste affects environmental quality and ecosystem health. In 2010, an estimated 5 to 13 million metric tons (Mt) of plastic waste entered the ocean from both developing countries with insufficient solid waste infrastructure and high-income countries with very high waste generation. We demonstrate that, in 2016, the United States generated the largest amount of plastic waste of any country in the world (42.0 Mt). Between 0.14 and 0.41 Mt of this waste was illegally dumped in the United States, and 0.15 to 0.99 Mt was inadequately managed in countries that imported materials collected in the United States for recycling. Accounting for these contributions, the amount of plastic waste generated in the United States estimated to enter the coastal environment in 2016 was up to five times larger than that estimated for 2010, rendering the United States’ contribution among the highest in the world.
