Industrial symbiosis (IS) is a key sub-field in industrial ecology. The field itself assists in developing strategies that support local and regional sustainable development. The evolution of IS is an important topic to be explored. In this paper, we use the system dynamics (SD) method to establish a model of the evolution of industrial symbiosis in the case of Hai Hua Industrial Symbiosis (HHIS). In this model, different scenarios for energy consumption, solid waste utilization, and wastewater utilization were set by changing the parameter values of certain input variables to analyze the evolution of HHIS. In addition, the drivers for IS evolution were investigated qualitatively in this study. The SD model was helpful for visualizing the effects and benefits of reducing the energy consumption, solid waste stock, and wastewater stock that were achieved by establishing symbiotic relationships during the evolution of IS. The results show that the optimization of energy and material flows and other symbiotic benefits can be achieved in HHIS. There are still some challenges that restrict the further evolution of HHIS. Some suggestions are proposed to promote its further evolution.

Due to the increasing scarcity of fossil fuels and the climate change, the importance of energy efficiency is increasing. This importance is major especially in areas where the energy consumption is high. Rail transport depicts such an area. The highest proportion of energy consumed in the railway is the so called traction energy. This energy is required for the train run. In the timetable, allowances leave a margin for the driving style of train run. By the selective use of strategies that change the driving style, it is possible to exploit these allowances and reduce the traction energy consumption. The first objective of this study deals with the development of algorithms for energy-saving driving style. First, the necessary input variables of the algorithms based on the literature research and the formulas of train dynamics were determined. Then the algorithms were developed to create different energy-saving driving styles, resulting choose the best result which should be shown as a driving recommendation. The developed algorithms were used in an application example in order to calculate the potential of energy-savings. The example should represent the influence of the input variables for a comparison of different situations. At last the acceptance of the determined driving strategies in practice was investigated. By implementing the design thinking method it was identified that driver advisory systems and training programs are necessary to facilitate energy-saving driving in practice.

Bali tourism development can lead to positive and negative impacts that threatening environmental sustainability. This research evaluates the hotel performance of the waste management that includes management of waste water, emission, hazardous, and solid waste by hotel that participate at PROPER and non PROPER. Research using qualitative descriptive method. Not all of non PROPER doing test on waste water quality, chimney emissions quality, an inventory of hazardous waste and solid waste sorting. Wastewater discharge of PROPER hotels ranged from 290.9 to 571.8 m3/day and non PROPER ranged from 8.4 to 98.1 m3/day with NH3 parameter values that exceed the quality standards. The quality of chimney emissions were still below the quality standard. The volume of the hazardous waste of PROPER hotels ranged from 66.1 to 181.9 kg/month and non PROPER ranged from 5.003 to 103.42 kg/month. Hazardous waste from the PROPER hotel which has been stored in the TPS hazardous waste. The volume of the solid waste of PROPER hotel ranged from 342.34 to 684.54 kg/day and non PROPER ranged from 4.83 to 181.51 kg/day. The PROPER and non PROPER hotel not sort the solid waste. The hotel performance in term of wastewater management, emission, hazardous, and solid waste is better at the PROPER hotel compared to non PROPER participants.

Municipal Solid Wastes

The management of municipal solid waste (MSW) appears to be one of the major ecological problems at present. Selecting sites for the disposal of municipal solid wastes or waste utilization facilities is one of the most contentious aspects of waste management. The present study aimed to develop the methodology to assess the natural protection of the geological environment from contamination upon the implementation of large ecological projects due to the allocation of MSW utilization facilities. The case of the Central Federal District of Russia (CFD) is taken as an example. The suitability of territories for municipal solid waste disposal is assessed according to the presence of weakly permeable deposits in the geological cross-section and their occurrence mode. A “map of engineering geological zoning CFD by the conditions of allocation MSW disposal sites and utilization facilities” has been compiled to a scale 1:2500000. The map gives a general indication of the suitability of the planned sites for waste disposal within the regarded region and showed that, for the bulk of territory, the allocation of MSW disposal and management facilities requires undertaking additional measures for the geoenvironmental protection from contamination.

Potential of palm oil’s waste (solid) as ruminant feed in Pelalawan district of Riau ProvinceABSTRACT. The objective of this study was to know potential of solid waste in Pelalawan district, Riau province. Research was carried out from December 2007 – January 2008 in Pelalawan district by using 4 factories of Elaeis guineensis (PKS). The four factories that were used for data collection were PT. Multi Palma Sejahtera (MPS), PT. Inti Indo Sawit Subur (IIS), PT. Sinar Agro Raya (SAR) and PT. Musim Mas (MM). The results of study showed that solid waste in Pelalawan district of Riau province had a great potential. Production of solid waste in Pelalawan district was around 76.176 tons/year and carrying capacity was 5.132 animals unit. Farmers will use solid waste at large quantity if they raise livestock in commercially, for instance for fattening purpose. The strategies which can be applied to maximize solid waste utilization are through partnership between farmers and factories or local government pihak PKS.
