  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • South Texas Landfill − Case Study

    During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an additional ...

  • Improved well tuning achieved at a Landfill gas to Energy developer`s sites - Case Study

    Building and managing a high-BTU landfill gas to energy system can present many challenges, but it’s not as complicated as it might seem. The key: start with a healthy, consistently productive wellfield. Morrow Renewables, formerly South Tex Renewables, specializes in doing just that. Headquartered in Midland, Texas, they began in the natural gas industry before building a reputation as one ...

  • Comparison of phosphorus recovery from incineration and gasification sewage sludge ash

    Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty ...

  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Improving Life-Cycle Performance with Pavement Interlayers

    In an environment of limited and decreasing budgets in the private and public sectors, it is increasingly important that investments made in pavement infrastructure are maximized to their fullest potential. Pavement interlayers, also known as geosynthetics, can be integrated into asphalt mix overlay applications to limit the intrusion of water and reduce the reflective cracking, thereby promoting ...

  • Axion: is ‘storing’ waste plastics better than burning?

    As global temperatures head for potentially catastrophic levels, landfilling rather than burning waste plastics might be better for the environment, suggests Keith Freegard, Director of Axion Polymers. Landfill or incineration: what is the best disposal route for our waste plastic materials? Large numbers of energy-from-waste (EfW) plants exist right across Europe and many of ...

  • How to set up an office recycling program

    The Paperless Project states the average office worker uses 10,000 sheets of paper a year, and 45% of paper used by office workers is trash by the end of the day. CalRecycle reports that over 785,000 tons of recyclable office paper are disposed ...

  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Identification of groundwater contamination zone around a reclaimed landfill using carbon isotopes

    Chemical and isotopic analyses of groundwater from piezometers localized around a reclaimed landfill were performed in order to identify the boundaries of groundwater contamination zone. Spatial distribution of dissolved inorganic carbon (DIC) concentration and stable carbon isotopes in the groundwater was used to distinguish the piezometers localized within the contaminated aquifer. Background ...
