This document discusses the sanitary landfill project in Dompe, Sri Lanka. It provides background on solid waste management issues in Sri Lanka, including that the country generates over 6,000 tons of waste per day but only collects around 2,700 tons. It then describes the "Pilisaru" National Solid Waste Management Project and the plan to establish Sri Lanka's first sanitary landfill in Dompe as a pilot project. The document outlines the design of the landfill, including liner systems, leachate collection, gas recovery, and monitoring systems. It notes there was public protest against the landfill but also awareness programs. The document discusses pros and cons of the project and provides recommendations.
lLandfill are the major disposal route for municipal solid waste. Wastes in landfill experience physical and biological changes resulting in solubilization or suspension of high concentrations of organic matter in the landfill‘s leachate.
Source reduction and waste minimization, resource recovery and recycling, waste processing and treatment,combustion and land filling have all significantly affected the sufficiency of waste management systems.
Of all available management options for solid waste management, landfill disposal is the most commonly employed waste management worldwide.
The concept of common effluent treatment plant has been accepted as a solution for collecting, conveying, treating, and disposing of the effluents from the industrial estates. CETP concept helps small and medium scale industries to dispose of their effluents. The effluent include industrial wastewaters and domestic sewage generated from the estate

Due to rapid increase in the production and consumption processes, societies generate as well as reject solid materials regularly from various sectors – agricultural, commercial, domestic, industrial and institutional. The considerable volume of wastes thus generated and rejected is called solid wastes. In other words, solid wastes are the wastes arising from human and animal activities that are normally solid and are discarded as useless or unwanted. This inevitably places an enormous strain on natural resources and seriously undermines efficient and sustainable development. One of the ways to salvage the situation is through efficient management of solid wastes.
There has been a significant increase in MSW (Municipal Solid Waste) generation in India in the last few decades. This is largely because of rapid population growth and economic development in the country. Solid waste management has become a major environmental issue in India .The limited revenues earmarked for the municipalities make them ill-equipped to provide for high costs involved in the collection, storage, treatment, and proper disposal of MSW. As a result, a substantial part of the MSW generated remains unattended and grows in the heaps at poorly maintained collection centres.

Biophysical Aspects of Environment. Environmental assessment (EA) is the assessment of the environmental consequences (positive and negative) of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" (EIA) is usually used when applied to actual projects by individuals or companies and the term "strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review.
The purpose of the assessment is to ensure that decision makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an environmental impact assessment as "the process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made". EIAs are unique in that they do not require adherence to a predetermined environmental outcome, but rather they require decision makers to account for environmental values in their decisions and to justify those decisions in light of detailed environmental studies and public comments on the potential environmental impacts.

Using GIS to Manage and Analyze a Landfill - by Mike Michels, Vice President, Aaron Weier, GIS Director
GIS technology is essentially smart, computerized mapping that overlays a great deal of data on maps, providing a detailed, three-dimensional look at the geography of a landfill — “A place to put everything in one spot — you go to a map, click around, and find that information a lot more quickly.” Those three-dimensional maps also give managers clues where to place wells to monitor landfill water and gas flows, and where to drill to draw off landfill gas to burn for energy generation. Converting monitoring data to meaningful, clear maps with GIS helps landfill managers make better decisions faster.
This presentation was originally presented by Cornerstone's Executive Vice President (Mike Michels) at the 25th annual Solid Waste Technical Conference at Michigan State University.

Conclusion
DESIGN A LEACHATE COLLECTION SYSTEM FOR A SMALL CAMP SANITARY LANDFILLIAEME Publication
Sanitary landfill is still the most cost-effective and appropriate method for waste disposal in Iraq. The municipal solid waste has high moisture content of about 49.1% and density of 162.6 kg/m3. The organic fraction reaches about 79%. Based on the studies and reports of study area, the average waste generation rate was 0.45 kg/capita/day. The design of the base liner, leachate collection system, and final cover system for the study area landfill is described in this paper. Since the landfill is located in an arid environment, leachate generation is low and potential infiltration through the lining system is minimal. A 250 mm diameter drainage pipes have longitudinal slope 1% to reduce sedimentation and allow adequate flow capacity.
Water supply and sanitary engineering seminar reportTalhaManasiya
Uncontrolled pollution will destroy the ecosystem
and the process is irrecoverable. Hence the goal of
solid waste management is to minimise hazards to
environment due to indiscriminate disposal of
solid wastes. Based on the knowledge of solid
waste generation, characteristics and treatment
methods, certain materials can be recovered or re-
used and electrical energy can be generated.
In ensuring better sanitary environments for the people and promoting their general
health, the proper collection of refuse (solid waste), its haulage, treatment and
disposal with minimum possible nuisance or risk to public health are fundamental to
'solid waste management'.
This presentation in about solid waste disposal into the land. This presentation is made for educational purposes only. Some content might have copyright.
Sanitary Landfill:
A method of disposing of solid waste on land without creating nuisances or hazards to public health or safety, by utilizing the principles of engineering to confine the solid waste to the smallest practical area, to reduce it to the smallest practical volume, and to cover it with a layer of earth at the conclusion of each day's operation or at more frequent intervals as may be necessary.

This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
