Carbon Dioxide Co2

Bio-based materials gained momentum in recent years due to their origin from raw materials capable of self-regeneration, locally available and theoretically biodegradable, as well as for their natural ability to store carbon dioxide (CO2) within the biomass. In a circular economy and within the perspective of the diffusion of information, this reasoned catalogue compares their technical and environmental properties together with their availability within the European territory. The aim is to support stakeholders towards a conscious choice of products and, during the process innovation phase, to help them choose the raw materials for the composition of new building materials/components to be included in a “circular” market.

<p>ABSTRAK<br /><br />Kenaf merupakan tanaman penghasil serat alam yang memiliki banyak produk diversifikasi dengan nilai ekonomi tinggi dan ramah lingkungan. Kontribusi kenaf terhadap lingkungan juga dikenal melalui kemampuannya yang tinggi dalam menyerap karbondioksida. Karbondioksida (CO2) adalah gas penyumbang efek rumah kaca utama yang sebagiannya dihasilkan secara antropogenik. Penyimpanan karbon oleh tanaman menjadi salah satu langkah paling penting dalam mitigasi gas rumah kaca. Tingginya absorbsi karbondioksida oleh kenaf dipengaruhi oleh laju fotosintesis yang tinggi, meskipun kenaf termasuk dalam tumbuhan C3. Laju fotosintesis kenaf didukung oleh aktivitas RuBP karboksilase, konduktansi stomata, dan hasil biomasa tanaman yang tinggi. Laju fotosintesis kenaf mencapai 3-8 kali lebih tinggi dibandingkan pohon dan tanaman C3 lainnya. Berdasarkan biomasa yang dihasilkan, kenaf siap panen umur 4-5 bulan menyimpan 2,9-12,1 ton C/ha atau menyerap 21-89 ton CO2/ha/tahun tergantung pada manajemen agronomi dan kondisi lingkungannya. Dengan luas lahan kenaf di Indonesia saat ini kurang lebih 3000 ha, maka serapan CO2 per tahun mencapai 63-267 ribu ton. Selain sebagai penyimpan karbon dalam waktu lama, beberapa produk diversifikasi kenaf seperti interior dan komponen mobil, peredam suara, serta pulp dan kertas juga turut berkontribusi mengurangi emisi CO2 melalui penghematan energi, serta mengurangi laju deforestasi dan emisi gas berbahaya lainnya. Pengembangan kenaf diharapkan mampu membantu pemerintah Indonesia dalam upaya menurunkan emisi gas rumah kaca serta menyediakan bahan baku serat alam untuk kebutuhan industri yang ramah lingkungan.<br />Kata kunci: Kenaf, absorbsi karbondioksida<br /><br />ABSTRACT</p><p>Kenaf (Hibiscus cannabinus L.) Benefits in Carbon Dioxide (CO2) Sequestration<br /><br />Kenaf is a natural fiber crop that have a lot of diversified products with high economic value and environmental functions. Kenaf contribution to the environment is also known through a high ability to absorb carbon dioxide. Carbon dioxide (CO2) gas is the main anthropogenic contributor to the greenhouse effect. Carbon sequestration by plants became one of the most important steps to greenhouse gases mitigation. The high absorption of carbon dioxide by kenaf affected by the high photosynthetic rate, although kenaf belongs to the group of C3 plants. Kenaf photosynthetic rate supported by high RuBP carboxilase activity, high stomatal conductance, and high plant biomass production. Kenaf photosynthetic rate reaches 3-8 times higher than trees and other C3 plants. Based on biomass produced, kenaf ready for harvest on 4-5 months plant age saved 2,9-12,1 tonnes C/ha or absorb 21-89 tonnes CO2/ha/year depending on the agronomic management and environmental conditions. Nowadays, land area of kenaf in Indonesia is approximately 3000 ha, therefore the absorption of CO2 reaches about 63-267 million tonnes/year. As well as carbon sink in long time, some kenaf diversified products such as car interior and automobile components, sound absorber, and pulp and paper also contribute to reducing CO2 emissions through savings of energy and decreasing deforestation rate and other harmful gas emissions. Development of kenaf plantation is expected to help the Indonesian government in an effort to reducing greenhouse gas emissions as well as providing the raw materials of natural fiber for environmentally friendly industrial raw materials.<br />Keywords : Hibiscus cannabinus L., carbon dioxide sequestration</p>

Building sector is known as one of the biggest polluters, causing environmental pollution and carbon dioxide emissions, most of which are generated during the production process of building materials. Therefore, researchers and manufacturers have become increasingly interested in environmentally friendly materials with low energy consumption. Magnesium based cements are being studied as an alternative to a widespread material as Portland cement, thus reducing the temperature required for calcination. During this research, magnesium binder-based composites using two types of magnesium (local dolomite waste material and caustic magnesia) were produced. Within the framework of this study, several regimes of thermal treatment were used to produce low carbon dioxide and environmentally friendly magnesium binder composites. Physical, mechanical and thermal properties of obtained specimens were tested.

Carbon Dioxide Co2

Plastic production has been increasing at enormous rates. Particularly, the socioenvironmental problems resulting from the linear economy model have been widely discussed, especially regarding plastic pieces intended for single use and disposed improperly in the environment. Nonetheless, greenhouse gas emissions caused by inappropriate disposal or recycling and by the many production stages have not been discussed thoroughly. Regarding the manufacturing processes, carbon dioxide is produced mainly through heating of process streams and intrinsic chemical transformations, explaining why first-generation petrochemical industries are among the top five most greenhouse gas (GHG)-polluting businesses. Consequently, the plastics market must pursue full integration with the circular economy approach, promoting the simultaneous recycling of plastic wastes and sequestration and reuse of CO2 through carbon capture and utilization (CCU) strategies, which can be employed for the manufacture of olefins (among other process streams) and reduction of fossil-fuel demands and environmental impacts. Considering the previous remarks, the present manuscript’s purpose is to provide a review regarding CO2 emissions, capture, and utilization in the plastics industry. A detailed bibliometric review of both the scientific and the patent literature available is presented, including the description of key players and critical discussions and suggestions about the main technologies. As shown throughout the text, the number of documents has grown steadily, illustrating the increasing importance of CCU strategies in the field of plastics manufacture.

Subject. The article considers the concept of circular economy, which has originated relatively recently in the academic literature, and is now increasingly recognized in many countries at the national level. In the European Union, the transition to circular economy is viewed as an opportunity to improve competitiveness of the European Union, protect businesses from resource shortages and fluctuating prices for raw materials and supplies, and a way to increase employment and innovation. Objectives. The aim of the study is to analyze the incentives developed by the European Commission for moving to circular economy, and to assess their effectiveness on the basis of statistical analysis. Methods. I employ general scientific methods of research. Results. The analysis of the EU Action Plan for the Circular Economy enabled to conclude that the results of the recent research in circular economy barriers, eco-innovation, technology and infrastructure were successfully integrated into the framework of this document. Understanding the root causes holding back the circular economy development and the balanced combination of economic and administrative incentives strengthened the Action Plan, and it contributed to the circular economy development in the EU. Conclusions. The measures to stimulate the development of the circular economy proposed in the European Action Plan can be viewed as a prototype for designing similar strategies in other countries, including Russia. Meanwhile, a more detailed analysis of barriers to the circular economy at the level of individual countries and regions is needed.
