Hydrothermally-calcined waste paper ash nanomaterial as an alternative to cement for clay soil modification for building purposes

It has been observed that clay soil cannot be used for building design, unless it is modified by firing or with cement. Either method of stabilization can adversely affect the environment and public health just like indiscriminate dumping or open burning adopted in developing countries as the prevalent disposal technique for waste papers. This paper sought to examine the feasibility of using assorted waste papers to derive an alternative stabilizer to Portland Limestone Cement for modification of clay soil into composite materials suitable for building design. Specifically, clay-based composites were fabricated at 0 %, 5 %, 10 %, 15 %, and 20% replacement levels by weight with cement, and then hydrothermally-calcined waste paper ash nanomaterial (HCWPAN). Water absorption, sorptivity, bulk density, thermal conductivity, specific heat capacity, thermal diffusivity, flaking concentration, flexural strength, and compressive strength were investigated for each of the fabricated samples. Irrespective of the stabilizing agent utilized, 10% loading level was found to be the optimum for possession of maximum mechanical strength by the samples. Only samples with the HCWPAN content were found to be capable of reducing building dead loads and improving thermal insulation efficiency over un-stabilized clay material, if applied as walling elements in buildings. Generally, it was revealed that the cement and HCWPAN have comparable influences on the properties of clay soil, thus indicating that HCWPAN could be utilized as an alternative stabilizer to cement. In addition, the preparation of HCWPAN was found to be more energy-saving than that of the cement.

Assessment of Thermophysical and Mechanical Properties of Composite Panels Fabricated from Untreated and Treated Coconut Husk Particles for Structural Application

Large quantities of coconut husks generated are under-utilized. In developing countries, this situation warrants their disposal by open burning or indiscriminate dumping. Either practice adversely affects the environment and public health. In this study, test samples were fabricated from untreated coconut husk particles (UCP) at 0%, 25%, 50%, 75%, and 100% weight proportions with treated coconut husk particles (TCP) using epoxy resin as binder. Five representative samples were prepared per formulation and then subjected to various intended tests. The test results revealed water absorption, bulk density, thermal conductivity, specific heat capacity, thermal diffusivity, nailability, flexural strength, and compressive strength to be (24.88 ± 0.04) %, (459.78 ± 0.05) kgm-3, (0.0867 ± 0.0001) Wm-1K-1, (1573.76 ± 1.14) Jkg-1K-1, (1.198 ± 0.002) x 10-7 m2s-1, (100.0 ± 0.0) %, (11.94 ± 0.03) N/mm2, and (22.86 ± 0.04) N/mm2 respectively for the control sample with UCP content. Also, the respective values of the properties were (29.05 ± 0.06) %, (583.87 ± 0.05) kgm-3, (0.1009 ± 0.0002) Wm-1K-1, (1402.66 ± 1.45) Jkg-1K-1, (1.232 ± 0.004) x 10-7 m2s-1, (100.0 ± 0.0) %, (14.58 ± 0.03) N/mm2, and (33.27 ± 0.02) N/mm2 for the counterpart sample containing the TCP. All the samples showed better tendencies for thermal insulation performance compared to conventional ceilings like plywood, PVC, and asbestos. Thus, utilization of coconut husks as described in this study could alternatively help to solve the disposal problems of such wastes while availing building industries with suitable raw materials to manufacture cost-effective heat-insulating ceilings.

Correlation of publication frequency of newspaper articles with environment and public health issues in fire-prone peatland regions of Riau in Sumatra, Indonesia

Forest fires in peatlands emit pollutants to the atmosphere, affecting public health. Though air quality data and epidemiology information are helpful in the management of the environment and public health, they are not always available. We aimed to reveal the utility of newspaper articles for estimating the public health concerns posed by air pollution. Using the database of a local newspaper, Riau Pos, in Riau Province of Sumatra, Indonesia, we have studied spatiotemporal correlations between publication frequency of newspaper articles mentioning search terms relevant to health issues and Fire Radiation Power (FRP) of peatland fires. FRP from one of the NASA satellite databases has been used as an index of air pollution caused by peatland fires. Visibility data for airport operation were also used as an index of particulate matter concentrations. The study regions are primarily the fire-prone Riau Province and nearby areas in the central area of Sumatra, Indonesia, from 2009 to 2018. Newspaper articles related to public health are found to be associated with FRP and visibility, or regional air pollution.

Public Conceptions of Scientific Consensus

Despite decades of concerted efforts to communicate to the public on important scientific issues pertaining to the environment and public health, gaps between public acceptance and the scientific consensus on these issues remain stubborn. One strategy for dealing with this shortcoming has been to focus on the existence of the scientific consensus. Recent science communication research has added support to this general idea, though the interpretation of these studies and their generalizability remains a matter of contention. In this paper, we describe results of a large qualitative interview study on different models of scientific consensus and the relationship between such models and trust of science, finding that familiarity with scientific consensus is rarer than might be expected. These results suggest that consensus messaging strategies may not be effective.

ROLE OF ORGANIZATIONAL STRUCTURE ON CONSTRUCTION WASTE MANAGEMENT AMONG KUANTAN MALAYSIAN CONSTRUCTION INDUSTRIES

The construction industry is one of the sectors contributing to the Malaysian economy and is regarded as an important component of the Malaysian economy. At the same time, as the number of building projects rises, the amount of waste created by building projects also increases, which also has many negative effects on the environment and public health. To reduce the amount of waste created by construction projects, waste must be properly handled and effective practices in the management of construction waste must be implemented in all construction industries. This research paper aims to answer these problems above in order to: 1) to investigate the relationship between formalization structure and construction waste management in Pahang construction industries; and 2) to investigate the relationship between centralization structure and construction waste management in Pahang construction industries. Data were obtained from 107 respondents among construction companies in Pahang. The PLS-SEM technique was used to test both the measurement and structural models in this analysis. The outcome shows that there is an important connection between the formalization structure and the management of construction waste among the construction companies operating in Pahang. The structure of centralization and waste management for construction was also found to be positively associated in this study.

The Growing Relation between Environment and Public Health

Introduction: Environmental health is deteriorating worldwide. Evidence shows that exposure to air, water and soil pollution has caused many deaths worldwide, a trend that is increasing day by day. Health consequences from exposure to environmental pollutants range from cancer, lung disease, heart disease and a series health problems which often lead to death. The majority of pollution related deaths happens mostly in low and middle-income countries. Environmental and pollution health related issues are not getting the attention they deserve in Albania. The main purpose of this article is to identify the relationship between environmental problems and public health consequences, by analysing public policies, case studies and instruments for measuring environmental health indicators. The article also presents suggestions regarding development of Environmental Medicine in Albania, and Public Health Tracking methods. Methods: Qualitative method is thoughtfully used in this article. Specifically, literature review methodology is used to identify environmental indicators that directly affect public health, adequate policies and instruments for the protection of public health, as well as environmental health at the international and national level. Qualitative method is used to reveal and evaluate the topic through multiple facets covering relevant contextual conditions. This method helps identifying the link between public and environment health indicators in a real-life situation, and to understand the relationship between these indicators in the Albanian context. Results and Discussion: Albania lacks a specific measurement system of Environmental Public Health Tracking, as well an established methodology for linking environmental and public health. Potential capacities for measuring environmental and health indicators are limited at the national level, thus, the public health policies do not clearly and fully integrate environmental health indicators for the protection of public health. Vocational training in health and environment is being practiced through various disciplines, but there is a need for specialized environmental medicine health professionals, with adequate competences in the field. Conclusions: The correlation between environment and public health is gaining attention nationally and globally. As in other countries, the need for Environmental Medicine professionals is growing also in Albania. Strong correlations between of environmental pollution indicators (air, water, land pollution) and public health indicators (such as infant and general mortality, morbidity rates, respiratory diseases, etc.) have increased in the last years. Use of instruments (such as EPHT), a fully integrated university curricula and a specific discipline of Environmental Medicine should be made a priority not only nationally, but also globally as environmental problems such as climate change do not recognize national borders. In order to manage the rising cases, states need to be resilient, and build appropriate research based policies and action plans to prevent the occurrence of environmental related public health consequences.
