Transforming Plastic Waste into Porous Carbon for Capturing Carbon Dioxide: A Review

Plastic waste generation has increased dramatically every day. Indiscriminate disposal of plastic wastes can lead to several negative impacts on the environment, such as a significant increase in greenhouse gas emissions and water pollution. Therefore, it is wise to think of other alternatives to reduce plastic wastes without affecting the environment, including converting them into valuable products using effective methods such as pyrolysis. Products from the pyrolysis process encompassing of liquid, gas, and solid residues (char) can be turned into beneficial products, as the liquid product can be used as a commercial fuel and char can function as an excellent adsorbent. The char produced from plastic wastes could be modified to enhance carbon dioxide (CO2) adsorption performance. Therefore, this review attempts to compile relevant knowledge on the potential of adsorbents derived from waste plastic to capture CO2. This review was performed in accordance with PRISMA guidelines. The plastic-waste-derived activated carbon, as an adsorbent, could provide a promising method to solve the two environmental issues (CO2 emission and solid management) simultaneously. In addition, the future perspective on char derived from waste plastics is highlighted.

Carbon dioxide (CO2 )gases that dominated by anthropogenic activities causevarious negative impacts on the environment and surroundings due to increasing itsconcentrations in the atmosphere. There are some techniques to mitigate againstthe increase of CO2 which one is the utilization of phytoplankton cultured in a photobioreactor (FBR) as an natural absorber. In this study, the influence of input gas CO2flowrate on Chlorella sp at multiple tubular air lift photobioractor (FBR) was measuredin milk factory field. The CO2 flowrate continuesly was controled by 2 l/min and 1.5 l/mduring experiment. Result showed that Chlorella sp. have a good adapted ability of CO210-15% vol industrial emition. The experiment result stated that reactor capability atFBR-1 was lower than FBR-2. The reactor capability at FBR-1 and FBR 2 were 0,78 ±0,25 and 0,92 ± 0,36 g/l. media/day.

Carbon Dioxide Co2

A household unit of an existing apartment in which residents lived was selected, and the indoor air quality in each space of the unit was measured for analysis. Analysis of the measurement data indicated that the concentration of carbon dioxide (CO2) constantly increased beyond 1000 ppm when a resident stayed indoors for an hour or more. Specifically, the concentration of CO2 increased when the resident was asleep to a level wherein negative impacts on health were observed. Moreover, the inflow of particulate matter (PM) was mainly caused by natural ventilation from the outside rather than the behavior of indoor residents, which generated an insignificant amount of PM. This study proposes a new ventilation system for solving the above-described problems. According to the system, when a window is closed, the window cavity created between a new frame and the existing frame is utilized as an air path for ventilation. The application of this system ensures a stable amount of ventilation through forced ventilation and prevents the inflow of external PM. Moreover, this system was designed to recover indoor heat through the window cavity and facilitate the pre-heating of outdoor air through heat collection based on solar radiation during the day.

Industrial Demand

High accumulation of generated plastic waste is a growing concern. Alternatively, scientific efforts are underway to drive industrial demand to replace these products with superior quality, adequate biodegradable resources. Cyanobacteria are a versatile group of phototrophic prokaryotes capable of producing polyhydroxyalkanoates (PHAs) using sunlight and carbon dioxide (CO2) as a form of carbon and energy reserve. PHAs are appealing alternatives for traditional chemical plastics because these have to resemble characteristics, biocompatibility, and complete biodegradability. In this sense, this chapter aims to address the potential of cyanobacteria as a biodegradable alternative solution.

Recycle Plastic

In 2008, the estimate amount of landfill waste in Indonesia reached 38.5 million tons every year with the largest compositions are organic waste (58%), plastic waste (14%), paper waste (9%) and wood waste (4%). Among waste compositions, only plastic waste takes the longest time of decomposition, about 100-500 years. This is because the characteristic of plastic is unravel which can lead to pollution of land, water and air. To overcome these problems, many people try to find solutions for plastic wastes such as burn, bury and recycle plastic wastes. But, all these ways still have negative impacts for the environment and the safety of the workers who do the combustion process. Therefore, it is a conversion machine that can convert plastic wastes into fuel with pyrolisis system, it burn plastic wastes in vacuum condition. This machine has several advantages, which have a high calorific value of the fuel (equivalent calorific value premium), and this machine can reduce a lot of plastic wastes, reached 92 kilos/ 8 hour every day for 2 kilos reactor capacity, and it’s also safety for environment because the plastic wastes are burnt in the reactor with 900 °C heat. So, the process and the oil are not produces dioxine gas. The innovations of this conversion of plastic waste machine are, it has a continuous pipe that can put 0.3 kg of plastic waste within 1.5 minutes while the machine is operating.Keywords: plastic waste, conversion machine, pyrolysis, liquid fuel

Kebakaran dapat terjadi dimana saja salah satunya dapat terjadi di alat transportasi air yakni kapal. Kebakaran selalu menyebabkan hal-hal yang tidak diinginkan baik kerugian material maupun ancaman keselamatan jiwa manusia. Seiring dari kejadian tersebut musibah kecelakaan kapal yang disebabkan oleh bahaya kebakaran sangatlah mungkin terjadi. Salah satu yang dapat mencegah kejadian kebakaran pada kapal haruslah dapat mendeteksi dini kebakaran tersebut. Untuk mendeteksi dini terjadinya kebakaran dikapal maka dirancanglah sebuah alat proteksi kebakaran otomatisberbasis adruino. Dimana Arduino merupakan board yang memiliki sebuah mikrokontroller sebagai otak kendali sistem. Sistem otomatisasi atau controller tidak akan terlepas dengan apa yang disebut dengan ‘sensor’. Sensor adalah sebuah alat untuk mendeteksi atau mengukut sesuatu yang digunakan untuk mengubah variasi mekanis, magnetis, panas, sinar dan kimia menjadi tegangan dan arus listrik. sistem yang dirancang ini dilengkapi dengan beberapa sensor diantaranya adalah sensor apiUV-Tron R2868, sensor asap MQ-2 dan kemudian sensor suhuDS18B20. Mikrokontroller sebagai pengendali akan merespon input yang berupa sensor tersebut ketika data yang dibaca oleh sensor mendeteksikebakaran diantaranya mendeteksi adanya asap, kemudian api dan suhu. Sebagai output dari sistem berupa racun api (fire extinguisher)dimana kandungan yang ada pada racun api tersebut berupa Dry Chemical Powder dan Carbon Dioxide (CO2) yang fungsinya digunakan untuk memadamkan api serta dilengkapi buzzer sebagai alarm peringatan jika terjadi kebakaran.
