Analysis of the Physicochemical Characteristics of Distillery Wastewater at Habib Sugar Mills, Nawabshah

The aim of this study is to perceive the level of significant physicochemical characteristics of Distillery Wastewater (DWW) at Habib Sugar Mills, Nawabshah, Pakistan. Five locations in the mill namely spent wash, digester tank, distillery, primary treatment, and secondary treatment were selected for analysis of pH, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), and Chemical Oxygen Demand (COD) of the samples. The samples were taken on a weekly basis for four succeeding months, from January 2021 to April 2021 and the experiments were carried out in the laboratory by adopting standard procedures. The results revealed that the pH of the samples from spent wash was the lowest, whereas secondary treatment samples had the highest. On the contrary, the highest concentrations of TDS, TSS, and COD were found in the samples taken from the spent wash and the lowest from the secondary treatment. The pH values were found abruptly increasing in the digester tank due to the addition of calcium carbonate in the stream of wastewater after the spent wash. The COD concentration was found to rapidly decrease, from more than 106000mg/l in the spent wash to around 35000mg/l in the digester tank samples, and then to gradually decrease up to the final point of disposal. Overall, TDS, TSS, and COD values were higher during April, January, and February and lower during March. The level of pH was extremely low in the spent wash and did not meet the lower limits of standards and the other examined parameters exceeded the upper limits of WHO standards.

Role and scope of overall equipment effectiveness implementation in Indian sugarmill industries: A justified approach

Indian process industries have come a long way to modify their technological aspects. Although consumption of processed beverages and food is booming around the globe, Indian process industries such as sugar mills are still struggling to make the best out of their resources. So, it is needful to implement a valuable strategy such as overall equipment effectiveness, which is a product of performance, quality and availability. This execution will enhance performance as well as production by mitigating the faults in the processes, operations and activities. This study presents overall equipment effectiveness as a metric approach for measuring performance. Since limited literature is available regarding overall equipment effectiveness implementation in the processing units in India; there is great scope of this study and its benefits. This study will enhance the knowledge of the stakeholders as well as researchers and will encourage overall equipment effectiveness implementation in this sector.

Dominicans and Baseball

Baseball reflects the sacrifice, commitment, and determination that Dominicans displayed during foreign occupation (1916–1924; 1965–1966), dictatorship (1930–1961; 1966–1978), and the struggle for sovereignty. Success in international tournaments and as the birthplace of a majority of foreign-born players in Major League Baseball (MLB) fosters national pride and generates revenue. But baseball has also been marred bycorruption political interference and exploitation. After its late-19th-century arrival, baseball helped knit Dominicans together, overcoming geographic, racial, and class divisions. It became the national pastime during the first US occupation, when games against US forces asserted Dominican nationalism while anti-imperialist guerrillas battled in the mountains. Baseball encouraged a national identity based on competition and achievement. During baseball’s “Romantic Epoch,” men or boys of similar social standing organized teams and tournaments, sometimes recruiting top players regardless of race or class. Rivalries led teams to import players from Cuba and across the hemisphere, integrating the country into a transnational circuit of leagues and barnstorming. Interaction with other baseball-playing countries furthered competition for talent and led to Dominicans playing in the Negro Leagues. In the 1950s, factories, sugar mills, and the military sponsored clubs which competed in an amateur system that produced players like Juan Marichal and Manuel Mota. During the 1940s and 1950s, after US baseball integrated, competition for players pushed Latin American leagues to affiliate with MLB. Dominican organizers resumed national professional tournaments in 1951 and founded the Dominican Professional Baseball League in 1955. Financial and institutional support from Trujillo helped establish what became a baseball industry. Integration also brought opportunities for Dominicans in MLB, beginning with Ozzie Virgil in 1956 and Felipe Alou in 1958. Cuba’s prohibition of professional sport in 1961 coupled with the prominence of players like Alou and Juan Marichal drew attention to Dominican players. Over time, Dominicans developed prototype academies that now lie at the center of MLB’s player development system. More than a thousand Dominican recruits as young as sixteen train in these academies and compete in the Dominican Summer League with the goal of becoming major leaguers; most are released without leaving the island. While Dominican baseball has been a point of pride and opportunity for many Dominicans, it has also reflected the inequities of global capitalism. Despite criticism of the academy system for exploiting youth, tens of thousands seek the chance to play in the major leagues.

Evaluation of Production Efficiency using Data Envelopment Analysis at PT. Perkebunan Nusantara XI

This study develops an evaluation of production efficiency at PT Perkebunan Nusantara XI. Since the domestic sugarcane-based industry today faces many challenges of change. From 2017 through 2018, Indonesia became the largest importer in the world. The high demand for sugar imports is caused by national production that has not met domestic needs. PTPN XI is a state-owned enterprise (SOEs) engaged in agribusiness with the core business of producing sugar. At present, PTPN XI has a problem, which is decreasing production efficiency. This study attempts to design and identify the measurement indicators used to evaluate the production efficiency of PTPN XI using Data Envelopment Analysis. The research objective will be accomplished through the analysis of questioners filled by the expert in the company. Based on the calculations and peer group decisions obtained by several factories that are being referenced, including the Pagottan Sugar Factory, Panji, Prajekan, Wonolangan, and Wringin Anom. Variables that significantly affect the efficiency of PT Perkebunan Nusantara XI's sugar mills are labor, electricity costs, and production capacity variables.

Novel Treatment of Sugar Mill Wastewater in a Coupled System of Aged Refuse Filled Bioreactors (ARFB): Full-Scale

Sugar is the most important food supplement of our daily diet. During the production, sugar mills use a large volume of water and produce a significant amount of wastewater polluted with high organic compounds. Therefore, it is necessary to treat the wastewater before their disposal. For this reason, this article presents the results obtained from the monitoring of a coupled system of aged refuse filled bioreactors (ARFB) in full scale to treat wastewater from a sugar mill. The coupled system consists of two bioreactors (a primary one -ARFB1- and a rectification one -ARFB2-) arranged in a series with identical geometries. The ARFB1-ARFB2 system was evaluated in two stages. The first stage (maintenance period) for 28 weeks, and second stage (Zafra season) for 29 weeks. The system was fed with sugar mill wastewater (SMW) with a chemical oxygen demand (COD) of 2787 ± 1552 mg/L and 2601 ± 722 mg/L, respectively. As results, we observed a rapid stabilization of the system over 2 months. In addition, we found the ARFB1-ARFB2 system achieved an average COD removal of 94.9%, with a final effluent (E2) concentration below the maximum permissible limits of Mexican and international regulations for all analyzed parameters. Finally, the results of this study show that the ARFB1-ARFB2 full-scale novel technology is an efficient process for removal of the main contaminants that affect the wastewater from the sugar mills.

ENERGY EFFICIENCY OF INDONESIA’S SUGAR INDUSTRY BASED ON ECONOMIC FRAMEWORK: STOCHASTIC METAFRONTIER ANALYSIS

This study investigates the efficiency of energy use and technology gap in the Indonesian sugar industry and the factors influencing energy efficiency. Using the firm-level data of sugar mills in 42 regencies in Indonesia from 2010 to 2014, this study applies the meta stochastic frontier based on the input distance function. The metafrontier analysis is applied in sugar mills in the East Java province and other provinces in Indonesia. All the data used in this study are the secondary data taken from the Indonesian Central Board of Statistics. The results reveal that there is a large room to save energy consumption in this industry. The mills in East Java provinces have higher energy efficiency, technology gap ratio, and metafrontier energy efficiency compared to the mills in other provinces. According to the metafrontier energy efficiency, energy inefficiencies in both groups come from operational inefficiency and technology gap. The size of the mills and age of the mills have a positive relationship with the energy efficiency of sugar mills and the size of the mills is positively related to the technology gap ratio. Meanwhile, the productivity of labor and the types of ownership do not affect the energy efficiency and technology gap.

ECONOMIC ANALYSIS OF PRODUCTION OF ALCOHOL, POWER AND BIOCOMPOST IN SUGAR INDUSTRY OF KARNATAKA

Karnataka state stands 3rd position in terms of sugar production and 4th position in cultivation of sugarcane in the India. In fact, there are presently around 64 working sugar factories with annual crushing capacity of 3.29 lakh MT/day, cogeneration capacity of 1500 MW/day, alcohol production capacity of 2100 KLPD and ethanol production capacity of 1130 KLPD. In the year 2017-18, Karnataka sugar industry had crushed a total of 347.5 lakh MT of cane and produced around 36.87 Lakh MT of sugar. The sugar industry in Karnataka is able to manufacture sugar in such huge quantities due to the fact that sugarcane is abundantly available in the state. But, Karnataka encounters up and down situations of sugar production and price fluctuations after few years. However, it is realized that the importance of integrated sugar-energy complexes to counterbalance the problem of wide sugar price fluctuation in domestic market. In the present work we undertook the cost-profit analysis of production of alcohol, power and bio-compost in sugar industry of Karnataka. We found that the economic returns on capital invested on sugar mills in Karnataka would be stable, if co-products i.e. bagasse, molasses and press mud are efficiently used for production of bio-ethanol, power and bio-compost.
