Contamination Events

The potential occurrence of guaiacol producing Alicyclobacillus in sugar products and in the sugar production process was evaluated. Final product testing revealed that granulated sugar products showed random background contamination while liquid sugar products were free from guaiacol producing bacteria. Contamination tracing in the sugar factory process showed that beet soil is a primary contamination route to a sugar factory. The bacteria were completely eliminated in the juice purification at all evaluated factories. Random re-contamination was observed in wash syrups from the A-station. Environmental contamination from air and surfaces could not be observed while 20% of human test subjects showed skin contamination of guaiacol producing bacteria. A successful elimination of guaiacol producing bacteria from sugar products was concluded to be unfeasible due to random re-contamination events in the sugar production process. It is suggested that the goal must be to evaluate realistic technical solutions located at the last step of the supply chain. Thermal and non-thermal treatment techniques are available and among those UV-treatment appears to be a promising elimination technique for TAB (thermophilic acidophilic bacteria) and GP-TAB.

Three Phase

The biodegradation of wastewater from the sugar industry is investigated in a three-phase biological fluidized bed reactor. In the inoculation experiment, the immobilized biofilm was found to keep dominant over the suspended biomass, and a stable biofilm of 175 microns thick was formed after 12 days. The continuous experiments for biodegradation of wastewater showed that, under the operation with hydraulic retention time of 3 h, the average COD and NH3-N removals reached to 85% and 80%, respectively, and the resultant effluent COD and NH3-N achieved the Chinese Discharge Standard of Water Pollutants for Sugar Industry (GB 21909-2008). The experiment for impact load showed that as the influent COD load changed stepwise from 2.3 to 5.1 kgCOD/m3·d, the reactor achieved the treatment effect without being affected in the performance. Finally, tracer experiments were performed to measure the internal circulation and residence time distribution (RTD) of wastewater in the reactor. It was found that the internal circulation of wastewater evidently exists in the reactor. Meanwhile, the RTD characteristics were described with the tanks-in-series model, and under the operating conditions, the calculated model parameter n was ranged from 1.19 to 1.27, which indicated that the flow pattern in the reactor is close to that in a CSTR. The internal circulation causes the organic matters in the influent to be effectively diluted within the reactor, and also promotes the organic matters to be fully degraded, so that the reactor can present high adaptability to the variation of organic load and high removal efficiency to COD and NH3-N. As a result, the biological fluidized bed reactor is suggested to be a prospective unit for the treatment of wastewater from sugar production process.

The Indonesian government has radically altered the structure of the national sugar industry by issuing Presidential Instruction no 9/1975 on the People’s Sugarcane Intensification Program (TRI) in order to increase sugar productivity. The dependence on the production process to sugar factories was replaced with the production process of the farmers from planting to harvesting. This research intends to document the socio-economic effects of the TRI program on farmers within the Mojo Sugar Factory work area in Sragen, Central Java, between 1975 until 1998. The result of the research has shown that farmers south of the Bengawan Solo river were resistant to the TRI program in favor of more lucrative rice farming. These farmers conducted social protests such as sugarcane field burnings. Farmers that lived north of the river supported the TRI program because planting sugarcane on non-irrigated fields was more profitable than planting other crops. This research shows that the TRI program has positively benefited to some farmers, a conclusion that is not shared by previous researches that point to only negative effect of the program.

Yield And Quality

During the processing of frozen and thawed sugar beets, invert sugar, in particular glucose and fructose, accumulates in them. This is due to the process of hydrolysis of carbohydrates. As a result of temperature fluctuations, beets lose elasticity, and tissue walls become soft. The activity of microorganisms intensifies on damaged beets. In the sugar industry, harmful microorganisms enter the production with raw materials, water, unwashed soil and air. Under improper storage conditions of raw materials the rapid development of microorganisms begins leading to sugar loss. The microflora of raw materials in sugar production is due to spore-forming and non-spore-forming bacteria, as well as micromycetes. Processing in the production of such raw materials is complicated. This leads to non-rhythmic operation of the sugar factory, technological processes and metal corrosion of technological equipment. Sugar yield and quality are significantly reduced. An important factor is the protection from the formation of microbial biofilms. The article considers the problem of formation of microbial biofilm in the process of obtaining diffusion juice in the sugar industry. The structure of the biofilm and its stability over time are considered. Under the conditions of active biofilm formation, uncontrolled unaccounted losses of sucrose are observed. Under conditions of low-quality beet processing, biocides and enzymes must be used in the production. They reduce the contamination of intermediate products by microorganisms, greatly facilitate the technological process. They also allow you to predict unaccounted sugar losses and improve its quality and yield. The article considers the effect of different types of biocides on dextran, which is an example of the formation of microbial biofilms. The comparative characteristic of influence of biocides on dextran is given and their resistance is noted.

Protein Rich

Aquaculture plays an important role in providing protein-rich foods, meeting the growing demand for fish. However, aquaculture is a potentially polluting activity, especially with regard to water pollution, due to the improper disposal of wastewater from the production process. Aquaculture wastewater is rich in nutrients (ammonia, nitrate, nitrite and phosphorus) and organic matter, and is commonly discharged into the environment without proper treatment. This can cause a series of environmental impacts and aggravate the current water crisis. Due to the importance and need to reduce environmental impacts, plan the use of water resources and achieve an efficient and sustainable production process, many researchers have focused their studies on effluent treatment techniques designed to remove these nutrients. This article therefore presents an updated review of the main physicochemical and biological techniques used in the removal of nutrients, which can mitigate environmental problems arising from aquaculture activities and contribute to the sustainability of the activity. Keywords: biological removal, nitrogen compounds, sustainable activity.

The beet sugar industry is facing several challenges for the future. The climate change is requiring a transition from the traditional fossil fuel to a greenhouse gas neutral energy source. The available possibilities for this purpose will be outlined in this paper. The recent EU sugar market reform has markedly increased the competition between sugar companies and the resulting lower sugar price has a significant impact on the profit margin of sugar production. In order to keep up with these challenges it is key to make an appropriate use of the available opportunities to improve the cost-efficiency of sugar beet processing. The different means to advance the sugar business are better asset utilization, continuous process improvement, introducing innovative process technologies and further developing a sugar factory into a biorefinery with a further valorisation of (co-)products and wherein synergy is obtained between different on-site process operations. Why and how these different available tools can improve the competitiveness of sugar factories will be discussed in detail. A proper combination and choice of the suggested changes and opportunities will enable sugar factories to get prepared for the future.

ABSTRACT Palm plants (Arrenga pinnata Merr) until now are not widely cultivated, but they are still forest plants. This plant can be used very much, both as a household appliance and as a home industry. The main results that are widely used in home industries are sap which is processed into palm sugar, which is then used as a sweetener in various kinds of cakes, drinks and others. This research was conducted to determine the factors that influence the production of palm sugar and to find out the risks in the small industry of palm sugar. From this study, it is expected to be used as a material consideration in advancing the palm sugar industry in rural areas, especially in the research area. This research was conducted in the Belimbing Village of Tabanan Regency, Bali. The results of this study indicate that only the factor of craftsman experience and the volume of roomie can affect palm sugar production, from five other factors that are suspected. Making palm sugar from sap material has a large risk of production of 115,587 kg, but it is still easily avoidable by craftsmen. With a risk threshold of producing 35.74 kg of printed palm sugar.
