Case study - Back Sand Point
As part of the £3.5 million hazardous landfill restoration project at involving 250,000 tonnes of restoration material we were contracted by local firm KLR to hydroseed over 100,000m2 in two stages using an Emorsgate wildflower seed mixture. In addition to the hydroseeding works, we also planted over 6,000 bare root trees and shrubs across the site, helping transform the once blighted land ...

Use of earthworms (Eisenia fetida) and vermicompost in the processing and safe management of hazardous solid and liquid wastes with high metal contents
Two feasibility studies using the earthworm (Eisenia fetida) and vermicompost in the processing and remediation of solid and liquid wastes with high metal content are presented: vermicompost as adsorbent substrate for remediation of wastewaters contaminated with metals; earthworms for remediation of arsenic (As) and mercury (Hg) in landfill soils. The feasibility of vermicompost for the ...

Transient and spatial modelling and simulation of polybrominated diphenyl ethers reaction and transport in air, water and soil
The release of the wastes containing polybrominated diphenyl ethers into the environment is a worldwide major concern. Investigation of spatial and temporal variations of polybrominated diphenyl ethers concentrations due to different factors, especially the transport of these species between air and water as well as between air and soil is the purpose of present research. A model was developed ...

Methane oxidation in water-spreading and compost biofilters
This study evaluated two biofilter designs to mitigate methane emissions from landfill vents. Water-spreading biofilters were designed to use the capillarity of coarse sand overlain by a finer sand to increase the active depth for methane oxidation. Compost biofilters consisted of 238-L barrels containing a 1: 1 mixture (by volume) of compost to expanded polystyrene pellets. Two replicates of ...

Mad Cow Disease / Chemical and Biological Weaponry
BAA Requirement: The Mobile system needs to be able to decontaminate and decompose 0.5 million pounds per 24 hour period of wet or dry animal and plant material that may contain some inorganic debris. The emissions, effluent and residue from this process must be environmentally safe and suitable for disposal in commercial landfills or waste treatment systems. The system must be able to ...

Resort Hotel Composting Food Waste in Cancun, Mexico - Case Study
Food waste composted with the in-vessel composter by XACT is solving the organic waste problem of an 8,000 room hotel in Cancun, Mexico. The Cancun Palace Resort generates 2500 tons of organic waste per year, and they wanted/needed to reduce their high waste haulage costs and landfill tipping fees. In addition, the hotel management wanted to take meaningful action to reduce their GHG emissions. ...

Organic Waste Compost Turning Equipment for sale in the United States - Case Study
It is not a good idea to dump organic waste into landfill and let it putrefy, as they poison the land and water-tables and release methane. In the process of economy development, people are keeping looking for effective ways to recycle the organic waste produced and collected every day. Compared with land-filling, composting is obviously a better alternative. Jack, one of our American customers, ...

Amelioration of physical strength in waste foundry green sands for reuse as a soil amendment
To avoid increasing costs of landfill disposal, it has become increasingly important for U.S. foundries to identify beneficial reuses for the 8 to 12 million tons of waste foundry sand (WFS) generated annually. A major drawback to the reuse of some WFSs as a soil amendment is their high soil strength, under dry conditions, where root growth may be limited. Fifteen WFSs were analyzed for strength ...

The Role of Eucalyptus Globulus Forest and Products in Carbon Sequestration
Abstract This study is a contribution to the ongoing debate about the selection of the approach for carbon accounting in wood products to be used, in the future, in the national greenhouse gas inventories under the UNFCCC (United Nations Framework Convention on Climate Change). Two accounting approaches are used in this analysis: the stock-change approach and the atmospheric-flow approach. ...

Munchinator reduces trash to compost-like product
The contraption looks a bit like a sophisticated high school science project as it rocks back and forth, with steam escaping and a slight rumble reverberating in the large room. The Munchinator is at work. A team of representatives from Carson City-based Ecologico Logic Inc. brought a prototype of their machine from their Southern California offices to South Tahoe Refuse this week to demonstrate ...

How thick and how long should a fish pond liner be?
How thick should a fish pond liner be? For the fish ponds, 0.5mm 0.75mm 1mm thickness is popular, because the pond liner should have a tensile strength, and puncture resistance, the sharp rock and tree branches cannot damage the pond liner easily. And these thickness is flexible, not heavy, easy to install. How long will a pond liner last? The pond liner can last 6-60years based on different ...

Composting of municipal waste in Poland
Composting constitute an important element of the integrated systems of municipal waste management, which is being developed these days. In such systems, the process is employed mainly in the treatment of selectively collected biologically degradable moist waste coming from kitchens, gardening and municipal green places. The biological treatment of mixed municipal waste, however, is employed ...
