The document describes the process for categorizing projects according to their potential environmental impacts to determine the appropriate level of environmental assessment. It provides definitions for 4 categories - A, B, C, and FI - based on the scale of impacts, from significant impacts requiring a full EIA (Category A) to unlikely impacts requiring only a review (Category C). The categorization is based on completing an environmental screening checklist to assess the project's impacts on sensitive environments and communities.

The project aims to reduce the total distance travelled by the fleet of vehicles for collection of municipal solid waste by planning new collection routes using Vehicle Routing Problem Solver (part of Network Analyst extension) in ArcGIS.
The document discusses sewage treatment in Lucknow, India. It describes two existing sewage treatment plants (STPs), Daulatganj STP and Bharwara STP, and notes that while they are working properly, not all wastewater is being treated. It also notes issues like insufficient biogas generation at Bharwara STP due to diluted sewage, and a need for tertiary treatment and water quality monitoring. Overall it evaluates the sewage infrastructure and treatment processes in Lucknow.
LCA stands for Life Cycle Assessment, which is a technique used to identify, measure, and characterize the potential environmental impacts of each stage in a product's life cycle from resource extraction to disposal. LCA aims to understand the flows of matter and energy involved in a product or process to find environmentally critical points and ways to prevent or reduce impacts. There are different types of LCAs depending on which stages are included, such as cradle-to-grave, cradle-to-gate, gate-to-gate, and wheel-to-wheel. LCA involves goal and scope definition, inventory analysis, impact assessment, and interpretation phases.
The document discusses factors to consider when locating and designing municipal solid waste transfer stations. It outlines key site location criteria such as proximity to waste collection areas, accessibility of haul routes, and avoiding traffic impacts. Design considerations include durability of materials, adequate size, and flexibility of layout. The size of transfer stations depends on waste storage needs, unloading time, and trailer loading rates. Station types include direct dump, hopper compaction, and push-pit compaction designs. Community acceptance requires informing residents about operations and siting through public meetings and media outreach.
The characteristics, quantities, volume and composition of solid waste generated may differ from one country to another and between urban and rural areas.
It depends mainly upon the customs, climate, living conditions and economic standard of the area. As a consequence, if solid waste management is to be accomplished in an efficient and orderly manner, the fundamental aspects and relationships involved must be identified, adjusted for uniformity of data, and understood clearly. This section deals about :Solid Waste Generation ; Solid Waste Handling, Storage and Processing at the Source.

This document defines key concepts in multi-criteria decision making (MCDM) including criteria, alternatives, and decisions. It provides examples of single-criterion and multiple-criteria decision problems. For multiple-criteria problems, alternatives differ in more than one criterion and criteria are often competing. Formal MCDM analysis is useful when criteria are competing and trade-offs are difficult to evaluate. The document discusses types of MCDM problems and contexts for MCDM including mutually exclusive alternatives, portfolio selection, design, and measurement.
waste water generation has become a big issue all over the world. Therefore understanding sewage treatment principles is necessary to plan a waste water treatment plant and resource recovery. This presentation discusses, what is waste water, composition of waste water and major functional units of a treatment plant
Industrial wastewaters have highly variable compositions depending on the industry and materials processed. They can contain high levels of total suspended solids, biochemical oxygen demand, and chemical oxygen demand. Unlike domestic sewage, industrial wastewaters may have pH levels outside the normal range of 6-9 and contain high concentrations of dissolved metal salts. The flow patterns of industrial wastewaters differ from domestic sewage in that they are influenced by the operations within a factory rather than daily living activities. Factors like shift work and batch manufacturing can cause wastewater characteristics to vary over time. Industrial wastewaters require consideration of parameters like biodegradability, strength, volumes, variations, and special characteristics that could impact treatment plant operations.
This document discusses source reduction of waste. It defines source reduction as actions that reduce or eliminate waste at the source before it enters the waste stream. This can include reducing packaging, making products more durable and reusable, and changing consumption habits. Source reduction provides both economic benefits through lower waste management costs and environmental benefits by reducing pollution, resource use, and emissions. Government policies like packaging restrictions and taxes can encourage more source reduction. Effective source reduction requires planning to identify reduction goals and strategies.
This Presentation deals with Physical and Chemical Characteristics of Solid waste Sample, with Importance of every characteristic in the field of Solid Waste Management
This document discusses various multi-criteria decision making (MCDM) methods. It describes the objectives and steps in MCDM methodology. Three MCDM methods are explained in detail: Compromise Programming (CP), Preference Ranking Organisation METHod of Enrichment Evaluation (PROMETHEE), and the Weighted Average Method. An example is provided to illustrate the application of each method.
This document summarizes a seminar presentation on solid waste management and landfilling. It defines landfilling and describes the key aspects of landfill design, including cell construction, waste placement, compaction, and daily cover. Advantages of landfilling include providing waste disposal and potentially reclaiming land, while disadvantages relate to environmental and health impacts if not designed properly. Factors affecting landfill gas production and different methods of landfilling like excavated cells and area methods are also summarized.
Environmental conservation by Randdel DelgadoRanddel Delgado
This document discusses environmental issues related to land, water, and air pollution and their effects. It notes that land degradation occurs from mining, improper waste disposal, and overuse of chemicals, which leads to increased pollution, disease spread, and low crop yields. Water pollution from waste, oil spills, and fishing impacts drinking water quality and causes fish kills. Air pollution from vehicle emissions and factories causes respiratory illness, global warming, and disease spread. The document recommends proper waste management, law enforcement, and green initiatives to address these issues and conserve the environment for future generations. Youth are encouraged to help by planting trees and properly disposing of trash.
This document is a thesis written by Sean Mc Garry on the topic of air pollution in the built environment. It examines how particulate matter concentrations vary with height above ground and the surrounding landscape. The document contains an introduction on particulate matter and its health impacts. It then describes the equipment and area of study used, the methodology, results from measurements of particulate matter at different heights and locations, a discussion section, and conclusions. The overall aim is to better understand how particulate matter levels are influenced by vertical location and the building landscape.
The document discusses various waste processing techniques and energy recovery methods, including physical, chemical, and biological transformations of solid waste. It focuses on composting processes like aerobic composting, anaerobic digestion, and vermicomposting. Aerobic composting uses microorganisms and oxygen to break down organic waste into heat, water and carbon dioxide. Anaerobic digestion generates methane gas from organic waste in oxygen-free conditions. Vermicomposting employs earthworms to produce nutrient-rich compost from organic materials.
Chemical characteristics of sewage and their testing Ankit Gola
The document discusses the chemical characteristics of sewage and their testing. It describes various tests that are carried out to determine characteristics like total solids, suspended solids, pH, chloride content, nitrogen content, fats/greases/oils, sulphides/sulphates, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD). These tests help indicate the stage of sewage decomposition, its strength, and the type of treatment required to make it safe.

• Tam, kad skirtingose alternatyvose pateikti projektai būtų sėkmingai įgyvendinti (gyvybingi), namų
ūkių sąnaudos turėtų išaugti skirtingoms alternatyvoms nuo 4,01 iki 6,07 Eur/namų ūkiui/per metus.
Tai sudaro 7–12 proc. nuo n. ū. sąnaudų, skirtų atliekų tvarkymui88.
• Apibendrinant rezultatus, optimali projekto įgyvendinimo alternatyva – IA alternatyva (MVA
surinkimas tik miestuose virš 50 000 gyventojų, apdorojimui išnaudojant turimus RATC MBA
pajėgumus);
• Atsižvelgiant į tai, kad projektai sukuria labai mažą socialinę-ekonominę naudą (priežastis: ir šiuo
metu MVA yra tvarkomos, todėl jų tvarkymo nauda yra priskiriama MBA, kurie nėra numatomų

14. KAIP REIKĖTŲ PARUOŠTI MVA IKI APDOROJIMO
• Smulkinti tik taip, kad plastikiniai maišeliai netaptų mikro plastiku;
• Netinka abrazyviniai pulpos gaminimo metodai, nes susidaro labai daug mikro plastiko ir pagaminti
kompostą praktiškai neįmanoma, o nuotekas panaudoti žemės ūkio poreikiams irgi yra
neįmanoma.
• Taikant išspaudimo metodus gaminant pulpą, labai daug organikos lieka išspaudžiamoje masėje;
• Pasiteisinęs būdas- minimalus smulkinimas suplėšant visus maišelius, maišymas su struktūrine
medžiaga pagaminta iš žaliųjų atliekų ir sausas anaerobinis apdorojimas arba kompostavimas bio
tuneliuose.
• Kompostas gaminimas sijojant žvaigždiniu separatoriumi - o po to gravitaciniu separatoriumi.

• Ar surinkimo konteineriai hermetiški ar kvėpuojantys?
• Koks minimalus maisto atliekų dažnumas yra priimtinas?
• Kokiomis mašinomis galima rinkti maisto atliekas?
• Kokiais smulkintuvais maisto atliekas sutraiškyti iki 12 mm dydžio?
• Kaip išvirti 200000 tonų maisto atliekų ne mažesnėje nei 70 ⁰c?
• Kur brandinti kompostą, jeigu to negalima daryti kartu su kitomis iš
