Indonesia is recognized as a country with high potential in maritime resources. However, Indonesia is also known as the second-largest contributor to plastic waste in the ocean. It is estimated that Indonesia contributes around 200,000 tonnes of plastic disposals. The highest pollutant of the plastic product was found to be cigarette butts. The trillions of cigarette butts generate chemical contamination the ocean waters. Chemicals that leach from the cigarette butts are extremely toxic to the aquatic life in the ocean. The marine pollution caused by this contamination was never seriously noticed, even though the huge number of cigarette butts were found in the sea. A grave concern should be shown on the impacts of the cigarette butts to the ocean. The objective of this article is to elaborate on Indonesian law dealing with the issue the cigarette butt pollution contaminating the oceans of Indonesia.This article is the result of normative research which analyzes exiting statutes and cases that aims at protecting the marine ecosystem from the cigarette filter disposal. This research attempts to analyze the existing laws and regulations in Indonesia on the protection of the marine ecosystem from toxic and hazardous wastes, especially from cigarette butts waste disposal. The results of this study show that to date there is no specific regulation dealing with tobacco waste product disposals. Accordingly, the government is suggested to enact a set of specific and effective regulations pertaining to tobacco waste products as done by some developed countries or states such as Singapore and Australia, so that marine pollution caused by cigarette butts could be prevented.

Affordable housing has remained a major challenge in Nigeria, as housing costs have continued to rise beyond the reach of the low income population. This paper explores the use of waste products like rice husk as alternative materials for housing construction. Rice husk is abundant as a waste product in areas where rice is processed commercially in Southeast Nigeria. The aim of the study is to create rice husk blocks that are cheap, lightweight, and appropriate for use in low income housing construction. The study was conducted through experimentation in the Building Technology workshop of Federal Polytechnic Nekede. A series of trial mixes were done involving a wide range of materials and mix proportions. Rice husk, Portland cement, and cassava starch, were found to be the most appropriate components for the blocks. The blocks produced were of good appearance, and lightweight. Five samples of solid core blocks measuring 150x150x150mm were tested in Strength of Materials laboratory of the Federal University of Technology Owerri. The average compressive strength of the blocks was 0.26N/mm2, which is below the Nigerian Industrial Standard NIS 87:2007. The blocks produced were considered appropriate for use as non-load bearing partitions and not structural walls. The result of the study is promising because the rice husk blocks help address the waste management problem in affected areas, and could also be an important component of a potentially useful material. This paper recommends further research in the area of improving the strength of the blocks, to make them usable as structural components in low rise buildings.

The upsurge of abattoir operations as a result of the rise in demand for meat protein has led to a corresponding increase in waste generation. These wastes are often channelled into nearby streams with little or no treatment which exposes aquatic organisms to the resultant consequences of this waste deposition. This study was thus aimed at determining the physicochemical quality of some abattoir samples in Port Harcourt city. Soil, faecal matter, wastewater, waste blood and service water samples from the Iwofe, Rumuodomaya and Trans-Amadi abattoirs were collected within a  period of one year and the pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD5), sulphate, chloride, temperature, nitrate, ammonia and heavy metals quantities including chromium, lead, zinc, cobalt, copper and cadmium were determined using standard techniques. The study recorded high BOD5 and COD values from the blood, faecal matter, soil and wastewater samples while service water samples had values within the Nigerian Standard for Drinking Water Quality limits. Seasonal variations in the physicochemical parameters of the samples collected both in the wet and dry seasons were observed. The pH values ranged from 6.2-8.5, BOD5 of blood, faecal matter soil and wastewater ranged from 2124-4349 mg/l while the COD ranged from 2715-8820 mg/l. In Rumuodomaya, the BOD5 and COD ranged from 2276-2727 mg/l and 2583-3245 mg/l respectively while samples from Trans-Amadi abattoir had values for BOD5 and COD ranging from 2253-4330 mg/l and 2931-4597 mg/l, respectively. Nitrate, chromium, cadmium, zinc, cobalt, lead and copper contents in the different locations varied statistically at α-0.05 while no significant difference was observed for pH, ammonia, temperature, COD, BOD5, sulphate and chloride contents at α=0.05. The BOD5 and COD of waste blood, wastewater, soil and faecal matter recorded values that were above permissible limits for service water and therefore raises concern for the aquatic life being threatened by these effluents as the amount of dissolved oxygen available for them will be reduced as a pollution of the immediate environment, if these generated wastes are not treated before disposal.

The study was carried out on the present status of shrimp processing plant’s waste management in Bangladesh. A detailed survey was conducted during February to May, 2013 in order to collect some basic information on the present status of shrimp waste management at shrimp processing plants through questionnaire interview on the various parameters. Information was collected from 52 plants of Khulna, Chittagong and Cox`s bazaar region. All collected information were accumulated, analyzed and are presented in graphs, figures and tables. The study had revealed that about 671.84MT of shrimp was purchased in 52 plants in a day and from which 248.8 MT of waste product was produced during processing. The study results showed that about 80% of the plants sell their waste products and rest of the plants discharged their wastes into river (63.50%) and 91.42% of the plants treated the waste water before discharge. Based on the obtained results from this study, it could be suggested that shrimp waste can be used further in different ecofriendly ways. J. Environ. Sci. & Natural Resources, 11(1-2): 73-81 2018

AbstractAs baleen whales recover from severe exploitation, they are probably subject to a wide variety of threats within the Antarctic marine ecosystem, including directed take. Here we review both the management and current status of Antarctic baleen whales and consider those threats likely to impact on them. Threats range from global problems - marine pollution and climate change - to localized issues including shipping, habitat disturbance, unregulated wildlife tourism and fishery activities. We identify the most pressing anthropogenic threats to baleen whales including scientific whaling and climate change. It is unclear whether current management approaches will be able to effectively encompass all these threats while also accounting both for the differing levels of scientific understanding and for the differing recovery rates of the whale species. For management we recommend the following: 1) incorporation of both ecosystem considerations and the suite of identified threats not limited to direct take, 2) identification of measurable indicators of changes in whales that allow more certainty in monitoring of populations and the environment, and 3) recognition of significant relationships between baleen whales and habitat features to provide information on distribution and use.

The Impact

Marine pollution occurs due to the entry of organized or unorganized, point or non – point land based releases of industrial, agricultural and residential waste. Biodegradable organic waste rich in microorganisms lead to potentially harmful effects and alter oxygen cycle, where as excessive inputs of nutrients like nitrogen and phosphorus stimulate algal growth leading to eutrophication.Thermodynamics play an important role in chemicals reactions occurring in ocean during degradation of organic waste. The rate of reactions is altered due to temperature and high salinities. This aspect is very crucial while predicting the self purification capacity of the water body. Adequate experimental work pertaining to the order of reaction and thermodynamic constants is essential to prove the basis of the predicted assimilative capacity of the system.In Mumbai, huge quantity of domestic waste is generated. Due to land restrictions, complete treatment of tertiary level is not feasible. The Municipal administrators take the advantage of coastal location and discharge this waste into the ocean with just meagre preliminary treatment. The disposal practices are advanced and well planned but still expected purification or dilution is not achieved in the near shore region. This has resulted in spoiling the impact zone of coastal areas creating stress on the living biota and non compliance of the marine water quality standards.Three major issues in coastal system, viz. Operation and control of waste discharges, degradation patterns of pollutants and  self purification capacity needs systematic  evaluation to  maintain favorable conditions for aquatic life. Hence it is essential to study the reaction kinetics and thermodynamic behaviour of the biodegradation of carbonaceous waste occurring under highly saline conditions. Experiments are conducted to confirm the kinetics and thermodynamics of biodegradation of domestic waste water into marine water at variable salinities. The paper presents the findings of kinetic behaviour particularly the values for rate of reaction, Activation energy and related constants.

Sugar Cane Bagasse Ash

Utilization of industrial and agricultural waste products in the industry has been the focus of research for economical, environmental, and technical reasons. Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry, along with ethanol vapor. This waste-product (Sugar-cane Bagasse ash) is already causing serious environmental pollution which calls for urgent ways of handling the waste. Bagasse ash mainly contains aluminum ion and silica. In this paper, Bagasse ash has been chemically and physically characterized, and partially replaced in the ratio of 0%, 5%, 15% and 25% by weight of cement in concrete. The Fresh concrete tests like compaction factor test, Slump cone test was obtained and hardened concrete tests like compressive strength, split tensile strength, flexural strength and Modulus of Elasticity at the age of 7 and 28 days was obtained. The result shows the increases in percentage of bagasse ash replacement, strength also increased.
