In Malaysia, waste management via recycling is highly promoted, however, recycling bins are not fully utilized as almost all the recycling bins provided are filled with other wastes. As institutional waste is a part of municipal solid waste (MSW), this composition study will be crucial to obtain a conventional management of the waste. In other words, waste composition studies are vital for a more effective and proper management of the waste generated. Hence, the objectives of the research are to analyse the trend of the recycle waste composition obtained during both semester session and semester break and to determine the recycle waste composition collected at UiTM engineering complex. Sorting of the solid wastes from the recycle bins are done manually before weighing of each waste category. The trend shows that paper has the highest composition both during semester session and semester break which is at 65% and 84% respectively followed by plastic bottle with 25% and 13% and aluminum can at 10% and 3%. A sample of recyclable wastes is taken from each recycle bins to the instrumental analysis laboratory for ultimate analysis. The ultimate analysis result shows 43.68% carbon and 1.27% nitrogen for paper wastes, which give a C/N ratio of 34.67. This indicates that paper wastes are compostable when mixed with yard wastes. In determining the economic benefits of recycling, potential revenue of RM78.37 can be obtained from a 10-week period of study and hence, if recycling practice is made compulsory, the revenue can be increased.

This article explores the tourism migration within the South African context, thereby focusing on the current dynamics, challenges and future prospects. Tourism and migration are significant towards globalisation. Almost all countries have jumped on the tourism bandwagon as a result of the positive economic benefits that include improving the balance of payments, attracting foreign exchange, and increasing state coffers through the taxation of non-residents. South Africa has also adopted tourism into the developmental policies. Although Africa's share of the global tourism market remains less than 10%, the continental bodies such as the African Union under the wing NEPAD recognises that tourism and migration as an important factor to societies. This paper adopts the content analysis to address the tourism migration, dynamics, challenges and future prospects as a critical phenomenon. Tourism has deep characteristics of a plantation economy that does not benefit the majority of the societies, particularly in South Africa. Despite being a geographical dispersed country, the tourism industry in South Africa faces numerous challenges such as the integration of Black South Africans as product owners; reported high rates of crimes, lack of integration of locals in the tourism industry, the lack of aviation competition, paucity of ports of entry, and most recently the cyber-crime and the visa regulations etc. However, South African tourism remains resilient as a major destination due to its fauna and flora and increasing market niches are developing such as adventure tourism, health tourism and volunteer tourism. South Africa plans to be one of the top 20 destinations by 2020; steps are in place to ensure that South Africa achieves this objective.

Metham Sodium

AbstractMethyl bromide (MB), a dominant ozone-depleting substance, is scheduled to be completely phased out for soil fumigation by December 30th 2018, in China. The combined effects of dimethyl disulfide (DMDS) plus metham sodium (MNa) were assessed in controlling soilborne pests for soil fumigation. A study was designed in laboratory for the evaluation of the efficacy of DMDS + MNa to control major soilborne pests. At the same time, two trials were conducted in cucumber field located in Tongzhou (in 2012) and Shunyi (in 2013), respectively, in order to assess the potential of DMDS + MNa in controlling soilborne pests. Laboratory studies disclosed positive synergistic effects of almost all four used combinations on Meloidogyne spp., Fusarium spp., Phytophthora spp., Abutilon theophrasti and Digitaria sanguinalis. Field trials found that DMDS + MNa (30 + 21 g a. i. m−2), both at a 50% reduced dose, effectively suppressed Meloidogyne spp. with a low root galling index (2.1% and 11.7%), significantly reduced the levels of Phytophthora and Fusarium spp. with a low root disease index (7.5% and 15.8%), gave very high cucumber yields (6.75 kg m−2 and 10.03 kg m−2), and increased income for cucumber growers with the highest economic benefits (20.91 ¥ m−2 and 23.58 ¥ m−2). The combination treatment provided similar results as MB standard dose treatment (40 g a. i. m−2) or DMDS standard dose treatment (60 g a. i. m−2) in pest control and yield, but was more effective than MNa standard dose treatment (42 g a. i. m−2). Usage of all chemical treatments gave better significant results than the untreated group of control. Considering the economic benefits, the DMDS plus MNa combination (30 + 21 g a. i. m−2) could be used for soil fumigation in cucumber production in China.

Economic Efficiencies

Abstract A common feature of previous studies about the application of data envelopment analysis (DEA) to determine environmental and economic efficiencies is that the two were analyzed in separate models or frameworks. The purpose of this paper is to analyze the economic efficiency and environmental efficiency with a single model. This paper proposes an integrated DEA model, based on a modification of the directional distance function, which allows us to decompose the eco-efficiency (EE) into the economic efficiency (ECE) and environmental efficiency (ENE). The ECE characterizes the ability of gaining economic benefits while the ENE characterizes the ability to control pollutant emissions in production activities. Identification of ECE and ENE can help decision makers of different regions detect what kind of factor (economic inefficiency or environmental inefficiency) is the main source of eco-inefficiency. This can help decision makers more targeted to improve EE. To illustrate the feasibility of our approach, a case study of 30 regions in China is presented. The empirical results show that almost all regions have very high economic efficiencies. The environmental inefficiency is the main source of eco-inefficiency. The differences of environmental efficiencies lead to the differences of eco-efficiencies in the east, central and west areas, while the economic efficiencies do not have significant differences among these areas. The economic efficiencies showed an opposite “V” shape and the environmental efficiencies showed a decreasing trend during the period 2010–2014.

Abstract Dealing with flooding in a densely populated flood-prone area poses complex challenges. Almost all residents realize that living in the area is hazardous. However, they choose to stay there. Therefore, flood risk management should be applied in the area. This study aims to: 1) develop facts of the local community in a flood-prone area in decreasing the flood risk while improving well-being through modifying drainage channels used for fish and vegetable farming; 2) evaluate all benefits of drainage investments include the social and economic benefits. The research method consists of a quantitative approach through the distribution of questionnaires and a qualitative approach through in-depth interviews and field surveys. In this study, a concerted community effort was developed as a design parameter. At the same time, the observation parameters include knowledge of the causes of flooding, knowledge of flood risk, community involvement, and government flood control programs. The results showed that the strength of concerted community effort was significantly influenced by the knowledge of flood risk and the local community involvement. This effort can decrease the flood risk by up to 30% and serve direct financial benefits of IDR 48 million in a year.

Meaningful Data

Waste composition studies can provide meaningful data for design and operation of resource recovery processes. However, relatively limited attention has been devoted to energy recovery predicted by waste composition analysis, despite increasingly detailed analysis of various subsets of the municipal solid waste stream. Further, global economic conditions and markets have dramatically altered since 2008, resulting in significant changes in corporate, institutional and consumer spending patterns. Associated with these shifts in spending, as well as with longer-term trends in packaging and advances in residential and commercial recycling, the quantity and makeup of discarded materials has changed. The authors present data resulting from recent waste composition studies, and discuss potential impacts on the design and operation of material recovery systems.
