Abstract: Robust waste management is highly considered the main issue universally and globally. Particles of tyre-rubber of used tyres and scrap elastic, used to replace element mixture in cement. The particles utilized to replace 11%, 16%, 21%, and 26% of the mixture element total volume. Applying tyre-rubber mixture in these purposes can aid in preventing toxic waste and overcoming the issue of stowing disposed tyres. In general waste tyre rubbers are expensive to store and also hazardous to handle at times. Therefore, couple of the advantages of using rubber aggregates in replacing coarse aggregates are cost reduction and minimization of hazardous incidents.

Keywords: Tyre – Rubber – Mixing – minimization.

Abstract: Despite many rural roads being in a terrible state, Kenya Rural Road Authority is authorized to control their construction, repair and maintenance and the government has spent considerably to guarantee it has competent people certified in their field of operations.  The goal of the research was to investigate the institutional elements impacting sustainability of KERRA (Kenya Rural Road Authority) projects in Nyeri County, Kenya. The research aimed to determine what factors such as resource availability and human resource efficiency on the long-term viability of KERRA initiatives. The research was conducted using a descriptive survey method that used both qualitative and quantitative techniques. Forty respondents were selected using stratified random sampling from a target of 45. Questionnaires were the major means of information gathering besides interview schedule. Quantitative data was examined using statistical approaches such frequency distribution, percentage, and mean. The data was analyzed using SPSS 25.0. From the regression findings, the study revealed that there existed a significant positive relationship between human resource efficiency and sustainability of rural road projects as indicated by β=.635, p=0.03<0.05, t=8.347. Resource availability has a significance positive influence on sustainability of rural road projects (β= 0.433, p = 0.01<0.05, t=7.882). The study recommends that the management should eliminate human resource efficiency in all its processes to allow for faster decision making in approval, disbursement, procurement and supervision. Management should allocate adequate financial resources, promote timely disbursement and enhance procurement to ensure all resources required for project implementation are provided just in time.

Keywords: Institutional Factors, Sustainability of Road Construction Projects, Resource Availability, Human Resource Efficiency.

Abstract: Abstract: Solid waste is generated continuously everywhere in our modern world and in Kuwait it is no exception. This paper presents Kuwait in terms of municipal solid waste (MSW) and municipal solid waste landfills (MSWL) and its impact on the environment, especially groundwater. Due to the recent rapid economic growth in Kuwait, municipal solid waste (MSW) production is growing rapidly as well. To minimize municipal solid waste and its negative impacts, it is important to assess its causes to be able to manage it properly. Kuwait follows a conventional municipal solid waste handling method by dumping the waste into allocated landfills, without properly compacting, covering, containing, or treating it. Therefore, the groundwater flowing under those municipal solid waste landfills is mostly contaminated, which is a health and safety issue that needs to be addressed. Now since the Environmental Protection Law No. 42 of 2014 and its Executive Regulation of 2017 are officially legally effective, more environmental efforts needed to spread pollution prevention awareness. For example, society members and politicians need to understand the pollution prevention hierarchy of avoiding, reducing, reusing, recycling and disposing. By minimizing the negative environmental practices, the related economical costs will minimize as well.

Couple of environmental studies here analysed the recent environmental situation in Kuwait and its impact on the environment, to provide scientifically engineered action plans to help manage environmental issues better and control its negative impacts, to protect the public health.

Keywords: municipal solid waste (MSW), municipal solid waste landfills (MSWL), Environmental Protection Agency (EPA), Driving Forces-Pressure-State-Impacts-Responses (DPSIR), and groundwater.
