Waste Treatment Plant

This article presents the technological processes associated with waste management on the example of the Municipal Waste Treatment Plant in Olsztyn. Legal acts regulating waste management and the maintenance of cleanliness at the municipal level are discussed. The Municipal Waste Treatment Plant in Olsztyn processes waste from 37 municipalities in the Region of Warmia and Mazury. Waste transported to the plant is separated into sorted waste and mixed waste which undergoes further processing. An innovative solution in the country of drying waste mixed in bioreactors, where aerobic biodegradation occurs, was applied in Olsztyn. As a result of the temperature in this process, the waste is dried without additional energy from the outside. Processed waste is used in the production of alternative fuel. Around 5-15% of the collected waste is not fit for processing, and it is landfilled.

South Moravia

The paper introduces and discusses the developed integrated economic model of municipal waste management of the Czech Republic, which was developed by authors as a balanced network model for a set of sources (mostly municipalities) of municipal solid waste connected with a set of chosen waste treatment facilities processing their waste. Model is implemented as a combination of several economic submodels including environmental and economic point of view. It enables to formulate the optimisation problem in a concise way and the resulting model is easily scalable. Model involves submodels of waste prevention, collection and transport optimization, submodels of waste energy utilization (incineration and biogas plants) and material recycling (composting) and submodel of landfilling. Its size (number of sources and facilities) depends only upon available data. Its application is used in the case study of the South Moravia region with verification of using time series waste data. The results enable to improve decision making in waste management sector.

Processed Waste

This article presents an innovative solution for drying waste in bioreactors on the example of the Municipal Waste Treatment Plant (ZUOK) in Olsztyn. Shredded mixed waste undergoes fermentation in bioreactors and produces heat for waste drying. Waste transported to the plant is divided into sorted waste which is recycled and mixed waste which is processed into different size fractions. Processed waste is used in the production of alternative fuel which can be burned in dedicated systems in cement plants or incineration plants. Around 5-15% of waste cannot be processed and is landfilled.

This summary presents the cleansing and dismantling operations currently realized on the CEA center of Saclay (CEA-Saclay). It was initiated at the beginning of the 2000 years a cleansing and dismantling program of the old Nuclear Licensed Facilities (NLF). Currently this program relates the dismantling operations to the Hot Laboratories (Laboratoires de Haute Activité: LHA) and the old workshops of the Liquid Waste Treatment Plant (Station des Effluents Liquides: STEL), the dismantling preparation of ULYSSE reactor and the dismantling studies to the Solid Waste Management Plant (SWMP; Zone de Gestion des Déchets Solides) and the OSIRIS reactor.

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants (POPs) into the atmosphere, including polychlorinated biphenyls, dioxins, and furans. The circumstances of exposure are detailed in Part 1, Background and Policy Issues. An ecologically based, staged health risk assessment was conducted in two parts with two levels of government as sponsors. The first, called the Swan Hills Study, is described in Part 2. A subsequent evaluation, described here in Part 3, was undertaken by Health Canada and focused exclusively on Aboriginal residents in three communities living near the lake, downwind, and downstream of the SHSWTC of the area. It was designed to isolate effects on members living a more traditional Aboriginal lifestyle. Aboriginal communities place great cultural emphasis on access to traditional lands and derive both cultural and health benefits from “country foods” such as venison (deer meat) and local fish. The suspicion of contamination of traditional lands and the food supply made risk management exceptionally difficult in this situation. The conclusion of both the Swan Hills and Lesser Slave Lake studies was that although POPs had entered the ecosystem, no effect could be demonstrated on human exposure or health outcome attributable to the incident. However, the value of this case study is in the detail of the process, not the ultimate dimensions of risk. The findings of the Lesser Slave Lake Study have not been published previously and are incomplete.

The Impact

The effect of discharging specific oil degrading bacteria from a chemostat to a refinery activated sludge process was determined biokinetically. Plant data for the kinetic evaluation of the waste treatment plant was collected before and during treatment. During treatment, the 500 gallon chemostatic growth chamber was operated on an eight hour hydraulic retention time, at a neutral pH, and was fed a mixture of refinery wastewater and simple sugars. The biokinetic constants k (days−1), Ks (mg/L), and K (L/mg-day) were determined before and after treatment by Monod and Lineweaver-Burk plots. Solids discharged and effluent organic concentrations were also evaluated against the mean cell retention time (MCRT). The maximum utilization rate, k, was found to increase from 0.47 to 0.95 days−1 during the operation of the chemostat. Subsequently, Ks increased from 141 to 556 mg/L. Effluent solids were shown to increase slightly with treatment. However, this was acceptable due to the polishing pond and the benefit of increased ability to accept shock loads of oily wastewater. The reason for the increased suspended solids in the effluent was most likely due to the continual addition of bacteria in exponential growth that were capable of responding to excess substrate. The effect of the chemostatic addition of specific microbial inocula to the refinery waste treatment plant has been to improve the overall organic removal capacity along with subsequent gains in plant stability.

As a rule, hazardous waste needs a pre-treatment, either a thermal or a chemical-physical one, before it can be disposed of at a landfill. The concentration of different kinds of treatment facilities at a Centralized Hazardous Waste Treatment Plant is advantageous. The facility of the ZVSMM at Schwabach is presented as an outstanding example of this kind of Treatment Centre. The infrastructure, the chemical-physical plant with separate lines for the treatment of organic and inorganic waste and the hazardous waste incinerator are described. Their functions are discussed in detail. Emphasis is laid on handling the residues produced by the different treatment processes and the final disposal.
