Leachate Reduction Using Duraskrim Liner

Mini-Technical Seminar

Tuesday, July 18, 2023 @ 10:00am

Delaware County Solid Waste Authority

Rolling Hills Landfill Facility

583 Longview Road

Boyertown, PA 19512

The Rolling Hills Landfill is undergoing a vertical expansion project that will extend the life the of landfill by nearly 17 years at current disposal rates. In August 2021, DCSWA received approval to begin construction of the Southern Area Expansion. The first phase included a 1,400 linear foot access road and 14-acre disposal cell. Construction of the access road was completed in December 2021 with final PADEP certification for the Phase 1 disposal cell in December 2022.

Due to the large size of the cell, and limited options for reducing the cell size while providing sufficient airspace for operations, BAI Group evaluated options to find ways to minimize leachate generation while providing the Landfill with operational flexibility. Based on the options and subsequent bid prices, DCSWA elected to install a 4-acre rain cover comprised of a 12 mil Duraskrim liner with Wind Defender to reduce leachate generation, provide UV protective for the underlying geotextile, and offer the Authority options to remove portions of the cover as waste filling dictated while still being able to divert stormwater.

BAI Group, DCSWA, Wind Defender, and Chenango Contracting Inc. personnel provided an overview of the project, Wind Defender and Duraskrim products, and installation. Orientation was at the landfill administration office followed by a vehicle tour of Southern Area Expansion.

York County Resource Recovery Center Waste-to-Energy Facility Tour Mini-Technical Seminar

Tuesday, August 2, 2022 @ 10:00am

York County Solid Waste Authority Education Center

2700 Black Bridge Road

York, PA 17406

An orientation session in the Education Center was followed by a walking tour of main areas of the waste-to-energy facility. Tour stops included a visit to the Tipping Floor, the Turbine Generator Room and a mock Control Room.  A networking lunch followed.

The York County Resource Recovery Center (YCRRC) is a waste-to-energy facility that converts municipal solid waste into ash and produces electricity. All of York County combustible household waste is managed at this facility. The YCRRC has been in operation since 1989. The YCRRC operates 24-hours a day, every day of the year and is designed to process 1,344 tons of waste per day.

The electricity generated by the facility is sold into the Pennsylvania-New Jersey-Maryland (PJM) grid. Under PA legislation, the YCRRC is designated as a tier II source of alternative energy. This means alternative fuel (garbage)–not a form of fossil fuel–is used in the production of electricity.

LCSWMA's Frey Farm Landfill Projects Mini-Technical Seminar

Wednesday, June 1, 2022 @ 10:00am

Frey Farm Landfill

3049 River Road

Conestoga, PA 17516

The Frey Farm Landfill looks very different than it did a few short years ago. The landfill is undergoing a vertical expansion project that will extend the life of the landfill by nearly 20 years. The second phase of the project is well underway and includes a 60-foot (at its highest point) by 1,600-foot MSE Berm. The total MSE Berm length for all three stages will be approximately one mile and include 9 acres of new lined area!

LCSWMA launched a visual landscape synthesis plan to help the landfill blend into the surrounding landscape. More than 500 trees and shrubs have been planted on completed portions of the landfill, along with allowing natural succession to occur. The initiative eliminates the need to regularly mow and reduces the terrace look and feel commonly associated with landfills. The project offers a variety of texture and natural color, as well as serves as a habitat for a whole host of animals, insects, and bird species.

In order to reduce landfill consumption and recover additional metal content in LCSWMA’s two waste-to-energy (WTE) facility ash streams, LCSWMA entered into a long-term contract with Blue Phoenix INASHCO Group to site a metals recovery facility (MRF). While LCSWMA’s WTE facilities currently use in-line metal recovery systems, only larger metals are removed. INASHCO offers an advanced metals recovery system to remove pebble-sized metals present in the ash. This includes both ferrous (iron) and non-ferrous (aluminum, copper, brass, zinc, gold, silver, etc.) metals. The MRF is now in full operation and recovers approximately 7,000 tons of metals each year.

Leachate Treatment for NPDES Discharge Mini-Technical Seminar

Wednesday, December 15, 2021 @10am

Lanchester Landfill

7224 Division Highway

Narvon, PA 17555

Presentation and a walking tour of the leachate treatment system followed by lunch and Q&A.

Members $15

Non-members $25

In early 2021, the Chester County Solid Waste Authority (CCSWA) commissioned a new leachate treatment system. This Mini-Technical Seminar included presentations by the operator, engineer, and equipment vendor on the project followed by a walking tour of the facility.

After multiple public bids that did not provide responsive offerings, Chester County Solid Waste Authority awarded a sole source contract for the design, permitting and equipment provision of a reverse osmosis leachate treatment system for the Lanchester Landfill. The system started operation in May of 2021, 12 months after award of the bid.

The new leachate treatment system offers almost twice the capacity of the system originally bid while offering better economics, especially in the provision of a lower volume of residual. The new leachate treatment system replaced an older, smaller leachate treatment system that was aging with maintenance and operating problems resulting in hauling leachate to offsite disposal outlets.

The project was awarded to Rochem Americas, Inc, who brought in Civil and Environmental Consultants (CEC) to help with permitting and installation design in the existing leachate treatment building. The project consisted of submittal and approval of a Water Quality Management Application to the PADEP, electrical and mechanical installation bid packages, installation bid review, and installation QA/QC.

Rochem supplied the Reverse Osmosis (RO) treatment skids and auxiliary tanks and process equipment. The modular design of the system allowed the arrangement to fit within the existing treatment building constraints, without the need for major structural modifications. Rochem also provided installation oversight, system commissioning, and operator training.

In the first 6 months of operation the system has discharged over 3,000,000 gallons of effluent under the CCSWA NPDES permit.

The Millfair Compost and Recycling Center is an inter-municipal effort between Millcreek and Fairview Townships (Erie County) that is located on the border of the two municipalities. The 5-acre composting facility has been open since 2004 and receives approximately 25,000 visitors each year.

Utilizing windrow-style composting methods, this facility accepts 1,500 tons of leaf waste and 5,000 tons of yard waste annually. The organic waste is processed into high quality compost and mulch products, which is then made available for sale back to residents, landscapers, and businesses of the community.

Composting leaf and yard waste is one small way communities can conserve natural resources and close the loop on recycling organics.

Solar Panels, ClosureTurf, and Roadway Reclamation (Oh My!) Mini-Technical Seminar

Tuesday, July 27, 2021 @10am

Lanchester Landfill

7224 Division Hwy

Narvon, PA 17555

Chester County Solid Waste Authority recently completed several innovative projects which will be presented:

Solar Panels: Panels were installed on top of the closed and capped Mountain Top Landfill, an unlined quarry fill. Once connected, the panels will produce 431.5 KW DC or 300 KW AC.

ClosureTurf: Construction was recently completed on an 8-acre section of ClosureTurf, the third ClosureTurf installation at the facility. ClosureTurf is a three-component final cover system comprised of a structured geomembrane, an engineered turf, and a specialized sand infill. Use of this final cover system eliminates the layer of final cover soils necessary above geosynthetics.

Roadway Reclamation: The main haul road through the landfill was reclaimed by milling down 15 inches while mixing in 7% by volume Portland Cement followed by a double asphalt chip seal. The process greatly reduces maintenance compared to a typical gravel roadway. The project also included radar investigation to find stormwater piping under the road and vacuum-truck cleaning of a 36-inch storm drain.

Natural Aquatic Life Treatment System Mini-Technical Seminar

Thursday, September 17, 2020 @ 10:00am

Greater Lebanon Refuse Authority

1610 Russell Road

Lebanon, PA 17046

The Greater Lebanon Refuse Authority has become a role model landfill because of its innovative natural wetland treatment system. Located on GLRA property is a series of 14 ponds that are used to treat leachate from an unlined area of the landfill. Vegetation around these ponds, cattails and water lilies, thrive on the nutrients in leachate and purify the water as it slowly flows through the pond system.

Eric Wiediger from Leachate Management Specialists (LMS) introduced natural systems for handling leachate, including phyto technologies with plants and trees, enhanced evaporation utilizing wind and salt-loving microbes, and constructed wetlands.  Natural systems strategically take advantage of natural processes such as solar radiation, evaporation, evapotranspiration, wind, plants, and biological activity to treat and eliminate liquid waste.

Presentation was followed by a tour of the Natural Aquatic Life Treatment System at GLRA, a series of 14 ponds that are used to treat leachate from an unlined area of the landfill. Networking lunch followed the tour.

April 24, 2019 - Seneca Landfill: CNG Facility Tour

Attendees toured the new CNG Fueling Station located at Seneca Landfill in Evans City, PA. Owned and operated by the Vogel Family who has been in business for over 60 years. They are the first company in Pennsylvania to capture the landfill gas that they generate, refine it into natural gas, and then compress it into CNG fuel used by the same vehicles that collect the waste deposited at Seneca Landfill.

Attendees learned about additional steps Vogel is taking to expand the use of its biofuel by turning it into a mobile pipeline. This project promotes the utilization of alternative renewable fuels (landfill derived biogas) instead of conventional diesel fuel to power a fleet of garbage vehicles and reduce the reliance on foreign and domestic oil. Compared to diesel, renewable natural gas has 27% lower carbon dioxide emissions, 80% lower greenhouse gas emissions, and 95% lower NOx emissions.

Also on this tour, attendees learned about Seneca's High BTU Landfill Gas processing plant that currently converts 2,200 scfm of landfill gas into 1,200 MCF of Natural Gas. This gas is distributed to the new CNG Fueling Station with the remaining natural gas being injected into the Peoples Gas pipeline, approximately 2 miles away.

March 21, 2019 - Foamed Glass Aggregates Mini-Tech & Facility Tour

Topics included the development, manufacturing, applications, physical properties and case studies for foamed glass aggregates.

AeroAggregates is in Eddystone, PA, on the former site of the Baldwin Locomotive Company. The Baldwin Company produced over 70,000 steam locomotives throughout their history which are in use around the world. Today, the facility is a vertically integrated producer of ultra-lightweight aggregates produced from 100% curbside collected glass cullet.

Foamed glass aggregates were originally produced in Scandinavia during the early 1990’s for use as a thermal barrier in road construction. Due to their very low bulk unit weight (8-15pcf), their applications have grown throughout the civil engineering market. Today foamed glass aggregates are used as lightweight fill on highways, bridge abutments, retaining walls, and green roofs. Other applications include backfill of foundations for drainage, insulation (prevention of frost heave) and reduction of lateral loads.

Foamed glass aggregates are produced from 100% post-consumer recycled glass. The material is inert and not effected by harsh chemicals or hydrocarbons.   

AeroAggregates is currently supplying several large DOT projects throughout the Mid-Atlantic region.

November 1, 2018 - Lancaster County SWMA Waste-to-Energy Tour
