The low-cost technology for landfill treatment and treatment of domestic waste
• Applications of the BIOPUSTER technology
• Remediation of contaminated sites
• Odour stabilisation in-situ remediation of landfills and contaminated soils
• Mechanical-biological treatment of "fresh waste"
• Highly efficient ventilation process for the aerobic phase
Biochemical decompositon by the controlled introduction of oxygen.
Biochemical decomposition - natural and environmentally-friendly.
Many micro-organisms specialise in the aerobic breakdown of biodegradable materials. For this reason, in nature, certain decomposition processes only take place under aerobic conditions, i.e. in the presence of oxygen.
If oxygen is added, these organism can break the materials down into their natural building blocks, mainly carbon dioxide and water.
BIOPUSTER for combined biological and mechanical treatment.
The BIOPUSTER. method is characterised by its modular structure. The waste is thoroughly mixed and the water content is optimised in an upstream homogenisation stage.
The prepared waste mixture is then placed in heaps up to 8 m high, where it undergoes intensive composting with the BIOPUSTER. Temperatures of up to 95°C can be achieved during this controlled treatment using artificially introduced oxygen. In this way, even compounds that decompose extremely slowly, such as lignins and cellulose, can he broken down and included in the biological decomposition.
The end products of the BIOPUSTER treatment are soil-like, permanently aerobic deposits. The resulting humin-like, highly caloric and heavy fractions are easy to separate out and sent for recycling in a controlled manner. It is not necessary to enclose the compost heaps since the effective extraction system allows the heaps simply to be covered with plastic sheeting. In addition intensive composting
means that if mobilisation of any contaminants does take place, it occurs beforehand during a controllable phase of the operation.
The following benefits provide significant cost savings:
• Shorter decomposition process through the uniform and accurate
introduction of oxygen
• Landfill volume is reduced by up to 50%
• Fewer contaminants in the leachate
• Odour emissions are prevented
• Permanently aerobic deposits reduce the cost of monitoring after site
closure
• The recyclable materials obtained can he reused
