This document discusses the importance of landfill lifecycle planning and staging to optimize operations and reduce costs. It notes that initial permit designs from the 1990s often did not adequately address operational needs. Drawing on 15 years of experience, it recommends reviewing staging plans to defer capital costs, increase waste density with no extra effort, and minimize operational expenses like road networks. The document provides examples of different staging options and their impacts on fill rates and operational timelines. Effective staging can help manage stormwater, leachate, and closure activities more efficiently over the lifespan of the landfill.

This document discusses the design and construction of secured landfills for disposing of various types of solid waste. It addresses municipal solid waste, industrial hazardous waste, e-waste, and biomedical waste. Key elements of landfill design include waste characterization, impervious liners to prevent leachate contamination, leachate collection systems, gas collection systems, and environmental monitoring. The document provides details on the multi-layer landfill lining system using clay and HDPE sheets, leachate wells and piping, gas venting systems, and other infrastructure needed to properly dispose of waste in an environmentally safe manner.

LandfillVanessa

��

A landfill is a carefully designed structure built into or on top of the ground for collecting garbage. Garbage is isolated from the environment by a bottom liner and daily soil coverings. Landfills can cause environmental impacts like pollution, methane gas emissions, and toxic leachate. Methane is a potent greenhouse gas and leachate is a highly toxic liquid that contains organic waste and can contaminate land and water sources. While landfills have negative environmental effects, they remain an important part of waste management infrastructure for dealing with non-recyclable materials.

Landfill leachate treatmentJohn Pravin

��

This document discusses methods for treating landfill leachate. Leachate is produced as water percolates through waste in a landfill. It contains high levels of organic and inorganic contaminants. The main goals of leachate treatment are to reduce environmental impacts and meet regulatory discharge standards. Common treatment methods include biological processes like aerobic and anaerobic treatment, as well as physical/chemical processes such as coagulation, flocculation, adsorption, and membrane filtration. Often, a combination of treatment methods is needed to sufficiently reduce contaminants in leachate before discharge or reuse.

Identification of appropriate landfill sites for City of ChittagongKazi Mahfuzur Rahman

��

ABSTRACT Urban solid waste management is a serious environmental issue confronting the cities in developing countries like Bangladesh. Apathy towards the problem, inadequacy of field level information and data, and resource constraints may be blamed for the dismal situation of solid waste management often visible in our cities. The most common problems associated with the absence of sustainable solid waste management practice include diseases transmission, odour nuisance, atmospheric and water pollution, visual blight, fire hazards and economic losses. In the three major cities of Bangladesh, Dhaka, Chittagong & Khulna, per capita production of solid waste is around 0.4kg /capita / day, but only a fraction of this waste is carried to the final disposal site. A recent study on Municipal Solid Waste Management, funded by Bangladesh Municipal Development Fund (BMDF), found that waste generated in Chittagong was 0.352kg/cap/day. Considering per capita generation of solid waste as 0.352kg to 0.4kg per capita per day, for a population of 25, 92,459 distributed within the 41 wards of the city (BBS 2011), total solid waste generated in Chittagong will be around 913 tons to 1037 tons per day in 2012. Currently, Chittagong City Corporation has only two dumping yards: one at Ananda Bazar, Halishahar at the mid western part of the city and the other at Arefin Nagar, Pahartali at the northern tip of the city. None of these sites are sanitary landfill. Considering the city area of 168 sq.kms, only two dumping sites are not sufficient to cater to the requirement of the city. Long distances between the collection points and the disposal site are responsible for inefficient utilization of the CCC trucks and the resulting increase in the haulage time that eventually increases the costs of collection and disposal. This paper aims to identify a number of appropriate landfill sites within the city for cost effective, efficient and safe disposal of solid wastes. An appropriate landfill site must satisfy environmental safety criteria and attributes that will enable the wastes to be isolated so that there is no risk to people and the environment. The criteria utilized for identifying appropriate landfill locations include natural physical characteristics as well as socioeconomic, ecological, engineering and land-use parameters. This study utilized Geographic Information System (GIS) and Multi-Criteria Decision Method (MCDM) for the identification and selection of appropriate landfill sites within the city of Chittagong. Thirteen sites were identified initially. Out of these sites four were found to be most appropriate and suitable for use as landfill. The sites thus identified, if utilized by CCC, are expected to bring a major change, in terms of cost effectiveness, efficiency and safety, in the current scenario of solid waste management in the city.

GIS - using GIS to manage and analyze a landfillCornerstone Environmental

��

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.

This document describes a study that used four different methods to assign weights to 17 criteria for selecting potential landfill sites in Najaf, Iraq. The four weighting methods were: ranking, rating, pairwise comparison, and trade-off. Geographic Information Systems (GIS) and Multi-Criteria Decision Analysis (MCDA) were used to integrate the weighted criteria and identify suitable landfill locations. For each weighting method, GIS and MCDA were applied to select potential sites. The results from pairwise comparison and ranking were similar, selecting five sites, while trade-off and rating identified more than five sites.

Particle Swarm OptimizationStelios Petrakis

��

Particle swarm optimization is a population-based stochastic optimization technique inspired by bird flocking or fish schooling. It works by having a population of candidate solutions, called particles, and moving these particles around in the search space according to simple mathematical formulae over the particle's position and velocity. Each particle keeps track of its coordinates in the problem space which are associated with the best solution that particle has achieved so far. The main idea is that hope flies along with the flock.

The Grady Rd. Landfill receives around 1200 tons of waste per day from various sources like restaurants, schools, and construction sites. The waste consists primarily of municipal solid waste (85%) along with some construction and demolition debris (10%) and special wastes (5%). At this landfill, the waste is not separated and is processed using equipment like evacuators, compactors, and bulldozers. The landfill structure involves filling the site in phases with double covers to prevent erosion and contamination of the surrounding area. Water monitoring of the leachate is conducted through groundwater wells and testing every 3 months.

Modern Landfill located at 4400 Mt. Pigsah Rd. in York, PA manages waste disposal through landfilling. While landfilling provides economic benefits, older unlined landfills have caused pollution issues. However, modern landfills are built with liners and systems to collect and treat leachate and gas to prevent pollution. Methane gas collected at landfills can also be used to generate renewable energy. While landfilling has downsides like odor and wildlife issues, proper management of modern lined facilities can safely contain waste.

#2: Good afternoon. Well, let me start off by telling you a little more about me.
#3: This is me.
#4: I’m from here.
#5: More specifically here.
#6: I live here, with my wife of 12 years and 3 kids in a modest house on a hill.
#7: In a town we really love.
#8: I was educated here. And here.
#9: I work here.
#10: Well, really I work here.
#11: Where I design these ... landfills that is.
#13: - click - Planning CAN and WILL save you money
#15: Many attempts failed
#16: Likely because of public opposition or political road blocks
#17: Your site was a success?
#18: Environmental protection is still paramount
#19: Little thought to sequencing
#20: Operations?
#21: Designers often “County Engineer”
#22: We have to live now, with the permits and plans that were often developed without significant or adequate experience based knowledge.
#27: Know what’s needed?
#28: Know what you have?
#29: Know how long it will last?
#30: Construct what’s needed.
#31: Height = density
#32: Maximize height = maximize density
#33: Don’t trap storm water - block or dig a hole (or know how to manage)
#34: Gravity flow where possible
#36: Anticipate construction materials needs/excesses.
#38: Total site soil balance is not staged soil balance
#39: Access to cell
#40: Extra haul distance? Temporary roads?
#41: Construction traffic on permanent roads?
#42: Solidification basins
#43: Leachate pump stations
#44: Cell Access roads
#45: Perimeter roads
#46: Haul roads
#47: Close phases as possible - larger unclosed area = higher financial assurance
#49: Sump Construction
#50: Phased capping
#51: Active face control
#52: Storm water management
#53: Daily cover management
#54: Construct sumps large enough for expected flow
#55: Depth matters for pump systems
#56: Temporary sumps are problematic
#57: Size tanks according to staged leachate flows
#58: Close areas as soon as possible to minimize infiltration
#59: Place adequate intermediate cover
#60: Small active face minimizes storm water infiltration
#61: Direct water away - berm
#63: Segregate storm water in newly constructed cell
#64: Divert storm water away from open cells
#65: Don’t puddle water on the cell
#67: Utilize alternate daily covers
#68: Strip soils (causes breakouts, gas flow problems)
#69: When to build
#70: How much area (volume) to build
#71: Bundle construction packages
#72: Upcoming solid waste permit issues
#75: OPTION 1
#76: Each successive cell seems to achieve maximum volume on long edge
#77: Geometry limits height
#78: I have seen phasing very similar to this
#79: 1 yr first cell
#80: 6.5 yrs cell 3
#81: 15 yrs cell 6
#82: 55 total years life
#83: OPTION 2
#84: Some cell sequencing not the most efficient NEXT cell
#85: But, we’re optimizing height
#86: Yr 6 - Option 2 provides 18 yrs life vs. 15 yrs Option 1
#87: Throughout Cells 6 through 12, Option 2 provides more life per cell
#88: Note that both options yield the same life
#89: This sequence maximizes volume by maximizing height
#90: The Egyptian Triangle - vertical cross section of the pyramids
#91: Pyramids utilize the Golden Ratio - that is the sides are of the ratio 1:sqrt(psi) where psi is teh golden mean or 1.61803
#92: Slightly more volume in Cell 4, makes up for loss in Cell 3
#93: Significant volume gain in Cells 6 and 8
#94: We can see for a given cell, beyond cell 5, Option 2 is constructed at a later date, thus saving expense costs
#97: Be knowledgeable, plan, make informed decisions
