Green GDP Indicator with Application to Life Cycle of Sugar Industry in Thailand

The objective of this study was to develop new indicators that reflect economic growth by taking into account the impact on the environment and natural resources as well. The indicator calculated by subtracting environmental cost from the “Gross Domestic Product (GDP)” and is used in the assessment of the GDP by taking into consideration the cost of natural resources and the environment, called “green GDP”. This study uses Life Cycle Assessment, which is a technique used to assess the environmental impact of sugar industry from raw materials, distribution, production, and waste management. The system boundary for the life cycle inventory are cultivation, planting, transportation and sugar production. The results of the green GDP and GDP is difference about 6–12% due to the depletion cost resulting from the use of natural resources between 9.0–9.52 $/ton of sugar production and the degradation cost caused by the airborne emission and waterborne emission between 37–57 $/ton of sugar production. The quantity of Total Suspended Particulate (TSP) generated from the sugar production process is the main causing the environmental cost about 55%. In order to solve environmental causes, the policy making as Circular Economy Strategies can be used to meet the sustainable development in the future.

INSIGHTS INTO THE COLLECTIVE BARGAINING PROCESS IN AN INDIAN SUGAR INDUSTRY: A STUDY

‘JUPITER’ sugars India LTD was founded in 1941 in southern India as a private sugar factory. Later it enhanced its production from 1000 TCD to 8500 TCD in the year 1962. It was amalgamating many subunits and multi locational products into its main unit. The company has focused its attention on various projects and substantial resources. Subsequently, they have decided to organize the company into two units one in southern India and one in northern India. Sugar industry is a vital agro industry largely depends on agriculture in India and is extremely accountable for creating a major impact on rural economy in particular and the country's economic status on broad-spectrum. Sugar production has a yield in the Indian subcontinent since ancient times. Then subsequently evolutes around the globe1. Sugarcane is a native of tropical Indian domain and spread over to the vital segments of world. Sugarcane plantation would be carried out twice in every year in India. The majority of the sugar production in India takes at regional sugar mills2. Subsequently in the post independence era India contemplated for overall augmentation of sugar industry3. The Indian sugar industry is independent in its energy needs and further makes additional exportable power through cogeneration. The different byproducts of sugar industry likewise add to the economic development of the nation to advancing various additional industries. Sugarcane has developed as a multi-product crop utilized as an essential raw material for the manufacture of sugar, ethanol, paper, electricity and besides a cogeneration of subsidiary product.

Sugar Beet Pulp in the Context of Developing the Concept of Circular Bioeconomy

The primary objective of this paper is to identify the possibilities of using sugar beet pulp as feedstock to produce a variety of added-value products. Such an application of the sugar production byproducts contributes to implementing circular bio-economy, which is a source of many economic, social, and environmental benefits. Specific objectives of this paper are: (1) Presenting the concept and meaning of circular bio-economy. (2) Characterizing properties of the sugar beet pulp from the perspective of using them as feedstock. (3) Determining the volume of production of the sugar beet pulp and the current methods of using them. (4) Determining the methods of obtaining attractive bioproducts and renewable energy from sugar beet pulp. Special attention was given to the amount of sugar beet pulp produced in Polish sugar refineries. Poland is among the European countries in which the volume of produced sugar is especially high. Therefore, the problem of appropriate waste management in the Polish sugar industry gains significant importance. The conducted literature review demonstrated that sugar beet pulp might be used as a feedstock in the production of many bio-products produced using a variety of methods.

The benefit of an artificial carbohydrates supply on Earth

<p>Our conventional, biogenic agriculture (CBA) has failed to provide a reliable concept to feed a growing population in a sustainable way. In particular CBA suffers from severe environmental externalities - such as the massive use of land area, water for irrigation, fertiliser, pesticides, herbicides, and fossil fuel.</p> <p>Here we suggest the artificial synthesis of carbohydrates from (atmospheric) carbon dioxide, water, and renewable energy, which would allow not only a highly reliable production without those externalities, but would also open the possibility to increase the agricultural capacity of our planet by several orders of magnitude. Our study shows that saccharose could be produced from CO2, water and electrical energy with an efficiency exceeding 30% equivalent to about 15 kWh per kg of sugar. Factoring in the efficiency of photovoltaic electricity generation we derive a „sun to sugar“ efficinecy exceeding 6%, which is about 10-times the efficiency of CBA sugar beets or sugar cane.</p> <p>All required technology is either commercially available or at least developed on a lab-scale. No directed research has, however, yet been conducted towards an industry-scale carbohydrate synthesis because the CBA carbohydrate production was thought to be economically more competitive. However, considering the environmental and socioeconomic externalities of the conventional sugar production, this economical narrative has to be questioned. We estimate the production costs of artificial sugar at about 1 €/kg. Today’s spot market price for conventional sugar is about 0.3 €/kg, however, we estimate its total costs (including external costs) at >0.9 €/kg in humid regions and >2 €/kg in semi-arid regions. Accordingly, artificial sugar appears already today to be the less expensive way of production. The artificial sugar production allows in principle also for a subsequent synthesis of other carbohydrates such as starch as well as of fats. These synthetic products could be used as a feedstock to microorganisms, fungi, insects, or livestock in order to enhance also the sustainability of the biogenic production of, e.g., proteins.</p>

Acid-Catalyzed Esterification of Betaines: Theoretical Exploration of the Impact of the Carbon Chain Length on the Reaction Mechanism

Betaine derivatives, especially esters, are compounds of interest for the development of a more sustainable fine chemistry, as they are widely available from biomass and currently produced as side-products from various industries (among which, sugar production). In this publication, we studied the impact of carbon chain length on three considered reaction mechanisms for the esterification of (CH3)3N(CH2)nCO2 betaine (n = 1, 2, 3) with glycerol under acid catalysis. DFT calculations show that the mechanism proposed by Bachmann–Frapper et al. may also be active here, but it can interestingly be seen as an avatar of the former proposition by Watson. Conversely, Ingold’s proposition is in this case too energetically prevented. Overall, lower activation barriers and higher reaction exergonicity are reported, suggesting esterification of longer carbon-chain based betaines is more readily achieved.

PENINGKATAN DAYA SAING USAHA PERKEBUNAN TEBU RAKYAT DI JAWA: TANTANGAN DARI PERSPEKTIF KEBIJAKAN / Improving the Competitiveness of Sugarcane Farming in Java: Challenges from Policy Perspectives

<p align="center">ABSTRAK</p><p align="center"> </p><p>Produksi gula dari usaha perkebunan tebu rakyat di Jawa hingga saat ini masih menjadi andalan produksi gula nasional, tetapi dalam lima tahun terakhir kontribusinya menurun sejalan dengan semakin menurunnya areal tebu. Kondisi ini menunjukkan bahwa daya saing usaha tebu rakyat semakin menurun yang diindikasikan oleh tingkat keuntungan yang terus menurun dan lebih rendah daripada usaha tani lainnya. Untuk meningkatkan daya saing usaha tebu rakyat diperlukan kebijakan pemerintah dalam rangka membantu memecahkan masalah atau mengatasi kendala-kendala, baik yang bersifat teknis maupun ekonomi. Tulisan ini bertujuan untuk mempelajari alternatif kebijakan teknis yang diperkirakan dapat membantu mengatasi kelangkaan sumber daya yang kemungkinan terjadi; serta mempelajari kemungkinan diperlukannya kebijakan pemberian insentif agar kebijakan teknis secara efektif dapat berjalan, melalui simulasi penetapan harga jual tebu dan gula. Alternatif kebijakan teknis yang bisa diterapkan untuk membantu mengatasi kelangkaan sumber daya yang terjadi pada sumber daya lahan, tenaga kerja, pupuk, benih tebu dan modal. Kelangkaan lahan mendorong terjadinya pergeseran budidaya tebu ke lahan kering, dengan potensi produktivitas lebih rendah, sehingga perlu pengembangan infrastruktur irigasi sederhana. Kelangkaan tenaga kerja terjadi berulang pada saat kegiatan puncak, sehingga perlu pola tanam tebu yang memungkinkan penerapan mekanisasi. Kelangkaan pupuk sering terjadi karena kegiatan pemupukan tebu bersamaan dengan usaha tani lainnya, sehingga perlu koordinasi antar lembaga terkait untuk menyediakan pupuk khusus untuk usaha tebu. Benih tebu bermutu sangat langka, sehingga perlu penyederhanaan peraturan penjenjangan kebun benih tebu, agar produksi benih dapat berjalan. Modal usaha tebu rakyat masih langka dan belum sepenuhnya dapat dipenuhi dengan penyaluran KUR Khusus Tebu, sehingga perlu kebijakan operasional untuk meningkatkan akses terhadap KUR. Selain itu masalah ketidakpastian harga tebu juga harus diatasi, melalui kebijakan penetapan harga jual tebu, yang sekaligus sebagai insentif bagi pekebun untuk meningkatkan produktivitas tebu.</p><p align="center">ABSTRACT</p><p align="center"> </p><p>Sugar production from smallholder farming in Java still has significant contribution to the national sugar production, however, in the last five years the contribution has decreased in line with the decreasing sugar cane area. This condition indicates that the competitiveness or profitability rate is decreasing and lower than other farmings. To improve the competitiveness, government policies are needed in order to assist in relaxing the constraints, both technical and economic constraints. This paper aims to study the technical policies that are expected to overcome the scarcity of resources that are likely to occur; as well as to study the possible incentive policies applied to support the technical policies, through simulations of the pricing of sugar cane and sugar. Alternative technical policies are applied to overcome resource scarcity in land resources, labor, fertilizer, sugar cane seeds and capital. Land scarcity has encouraged the shift of sugarcane cultivation to dry land, with lower productivity potential, so it needs the development of simple irrigation infrastructure. Labor scarcity occurs repeatedly during peak activities hence it is necessary to cultivate sugarcane patterns that allow the application of mechanization. Fertilizer scarcity often occurs because of sugarcane fertilization activities in concurrence with other farmings, so it is necessary to coordinate between related institutions to provide special fertilizer for sugar cane farms. Quality sugar cane seeds are very rare, so it is necessary to simplify the regulation of the classifications of sugarcane seeds, in order the seed production can run. The capital is still scarce and can not be fully fulfilled with the KUR (small scale credit program), so it needs operational policies to improve the access to KUR. In addition, the problem of sugarcane price uncertainty must also be addressed, through the policy of pricing of sugarcane, which also as an incentive for farmers to increase the productivity.</p>

Balance of sugarcane plantation land needs in Lamongan Regency in 2031 based on land-use changes using SPOT imagery

The volume of Indonesia's sugar imports in 2019 reached 4,09 million tons. The high volume of imports was influenced by the decreasing area of sugarcane plantations. Lamongan Regency is one of the sugarcane and sugar-producing regencies in East Java. Sugarcane and sugar production in Lamongan Regency has experienced quite diverse dynamics and has been influenced by changes in land-use conditions. This study aims to analyze the balance of land needs for sugarcane plantations in Lamongan Regency in 2031 based on an analysis of land-use changes using SPOT imagery of 2007, 2013, and 2019. The study was conducted by analyzing land-use changes, population projections, and land demand balance analysis for sugarcane plantations. The results of the analysis showed that the population of Lamongan Regency in 2031 is projected to reach 1.419.843 people with a land requirement for sugarcane plantations of 2.362,29 ha. There will be a land surplus of 1.276,92 ha but it is still concentrated in 7 of the 27 sub-districts. Sugarcane plantations in Lamongan Regency have the potential to be developed considering that the land allocation for plantations in the Lamongan Regency Spatial Plan of 2011-2031 reaches 10.022,42 ha.

Improvement of the liquid-jet sulfitators construction to increase the efficiency of sulfitation treatment of sugar production liquids

The article discusses and analyzes the construction of liquid-jet sulfitators used in the beet sugar industry. The importance of sulfitation treatment in the sugar beet processing and raw cane sugar technology is noted and the main advantages of its use at various technological stages are given, namely, preparation of extractant used for diffusion sucrose extraction out of beet cossettes, thin juice processing, thick juice with B- and C-remelts processing, as well as raw cane sugar remelt processing. The advantages and disadvantages of liquid-jet sulfitators in comparison with other constructions are noted and criteria for their improvement are given. It has been noted that the created ejection, which sucks in the sulphitation gas into the contacting chamber, and the fact that the absorption of sulfur dioxide occurs on a larger surface than in other types of structures the main advantages of liquid-jet sulphitators. The main disadvantages are the short length of the contacting chamber, which is insufficient for ensuring complete absorption of sulfur dioxide, as well as instability of the generated ejection when the productivity changes. This determines the criteria given in the article for the improvement of liquid-jet sulfitators. The description of the developed construction of the sulphitator centrifugal-jet nozzle of sugar production liquids is given, which provides: the stability of the sulphitation gas supply in a wide range of plant productivity; stability of the hydroaerodynamic regime of the system «treated liquid – sulphitation gas» inside the sulphitator; sufficient contact time for complete dissolution in the treated liquid of the sulfur anhydride contained in the sulphitation gas. The advantages of the developed centrifugal-jet sulfitators in comparison with typical liquid-jet sulfitators are noted: ensuring the operation range of 50-120% of the nominal capacity (plant production capacity); significant reduction in the technical sulfur consumption for the sulphur anhydride production, which is used as a reagent for the sulfitation treatment of liquids in beet sugar processing; reduction of harmful emissions into the atmosphere due to 100 % sulfur anhydride dissolution in the treated liquid.
