Hickory Ridge landfill outside of Atlanta

Summary

The installation of a solar array in Hickory Ridge Landfill is being considered. In order to ascertain whether significant financial gains could be realised, this project covers both technical and economic feasibility studies. With careful consideration for the particular construction limitations present in the landfill, the system could be built on the site. The land has reached its maximum capacity, and the locals wish to build a playground for their kids. These days, Hickory Ridge Landfill Company handles upkeep and operations. The replacement of the typical subtitle D closer, which covers a geomembrane liner of layer with soil and grass, with an alternative cap system that offers numerous environmental and financial benefits, makes the Hickory Ridge Landfill closer a significant milestone in the solid waste business. In order to maintain a grass-covered cap throughout time, shifting and soil replacement activities would release thousands of tonnes of greenhouse gases, which can be avoided with the use of solar energy cover. Reusable water can be collected without sedimentation or cleaning since rainwater pours down the geomembrane liner like water from a roof into a gutter.

Rationale/Proposal

Activity Description and Stakeholder Engagement

Republic Services is the private owner of the Hickory Ridge Landfill, a solid waste disposal facility located in Conley, Georgia, in the United States. An exposed geomembrane closure is significantly less expensive to install than a conventional closure. It is possible to replace long-term maintenance expenditures with a positive revenue stream by reinvesting construction and maintenance savings in solar panels. The Hickory Ridge Landfill solar energy cover technique offers numerous potential opportunities. This kind of environmentally friendly cap design can also be used to cover coal combustion products, allowing for the advantageous repurposing of full-capacity monofills and giving them a chance to serve as a platform for the production of renewable electricity. The photovoltaic effect, which is the direct conversion of sunlight into energy, is what happens in a solar photovoltaic cell. The quantity of electricity that each cell will produce is determined by the strength of the sun. To raise the output voltage or current, the photovoltaic cells can be linked in parallel or series. A solar panel is made up of one or more photovoltaic modules assembled as a pre-wired, installed-ready unit. A photovoltaic module is made up of connected photovoltaic cells that are laminated for protection. Moreover, a solar array is made up of several photovoltaic modules or panels that work together to create a whole power-generating system. A photovoltaic system comprises a mounting system, wiring, and an inverter in addition to the solar array and other balance of system parts. For the photovoltaic system to supply power to the grid, the direct current from the solar modules must be converted to alternating current using an inverter. In addition, the mounting method allows the photovoltaic module to be positioned and fastened in the best possible way to maximise the system's power production. A ground mounted system may feature a tracking system or a fixed tilt, and it may be ballasted on top or directly fastened to the earth. Photovoltaic systems are placed atop closed landfill sites in the novel and exciting concept of solar landfills, which combines the production of renewable electricity with resource-efficient land use. Solar cell technology has no moving parts, is a plentiful energy source, and is silent. Because there is no supply security associated with the world's reliance on limited fossil fuels, the current energy system is likewise in danger. Solar landfills are a potential new idea that aims to combine resource efficiency in land use with the production of renewable electricity. The global trends of the electricity trends market have been to decrease dependence on public entities and regulated monopolies and shift the focus toward the implementation of market mechanisms such as competition and private ownership. Through the implementation of regulatory rules, such as objectives for

renewables, the players in the renewable energy sector can build more confidence and more accurately predict the sector’s future advances. These goals also point to potential future instruments and regulations that could aid in the further growth of renewable energy sources. These goals, however, typically don't impose any legal requirements that guarantee they will be met.
