Anaerobic Digestion (AD) is a waste treatment technology widely used for wastewater and solid waste treatment, with the advantage of being a source of renewable energy in the form of biogas. Anaerobic digestion model number 1 (ADM1) is the most common mathematical model available for AD modelling. Commercial software implementations of ADM1 are available but have limited flexibility and availability due to the closed sources and licensing fees. Python is the fastest growing programming language and is open source freely available. Python implementation of ADM1 makes this AD model available to the mass user base of the Python ecosystem and it [prime]s libraries. The open easy to use implementation in PyADM1 makes it more accessible and provides possibilities for flexible direct use of the model linked to other software, e.g. machine learning libraries or Linux operating system on embedded hardware.

Chicken manure is an agricultural residue material with a high biomass potential. The energetical utilization of this feedstock via anaerobic digestion is an interesting waste treatment option. One waste treatment technology most appropriate for the treatment of stackable (non-free-flowing) dry organic waste materials is the dry batch anaerobic digestion process. The aim of this study was to evaluate the substrate suitability of chicken manure from various sources as feedstock for percolation processes. Chicken manure samples from different housing forms were investigated for their chemical and physical material properties, such as feedstock composition, permeability under compaction and material compressibility. The permeability under compaction of chicken manure ranged from impermeable to sufficiently permeable depending on the type of chicken housing, manure age and bedding material used. Porous materials, such as straw and woodchips, were successfully tested as substrate additives with the ability to enhance material mixture properties to yield superior permeability and allow sufficient percolation. In dry anaerobic batch digestion trials at lab scale, the biogas generation of chicken manure with and without any structure material addition was investigated. Digestion trials were carried out without solid inoculum addition and secondary methanization of volatile components. The specific methane yield of dry chicken manure was measured and found to be 120 to 145 mL/g volatile solids (VS) and 70 to 75 mL/g fresh matter (FM), which represents approximately 70% of the methane potential based on fresh mass of common energy crops, such as corn silage.

Survey results in 72 mechanical manufactures in Ho Chi Minh City, in conjunction with related studies show that the charge of industrial solid waste – hazardous waste treatment is operated in two forms: fixed or progressive based on the generated volume. Price of collection - transportation - storage - treatment - landfill for each waste composition is widely varying (5-20 times), depending on the agreement between production facilities and service units. Price is not yet able to handle the relationship with the treatment technology, treatment level to be achieved as well as the correlation to the transported distance and the extent of hazardous waste. Methodology for calculating the costs of industrial solid waste treatment by burning method is initially set. Treatment costs per ton of industrial solid waste of the mechanical industry are determined. The formulas are specifically built for each case of emissions, corresponding to different levels of load transportation.

A cost-effectiveness of a specific waste treatment technique is very important factor when making the decision to invest in a waste treatment facility. Waste treatment can bring economic benefit through the value of product: recycled materials, the compost, the generated electricity, or heat. However, the expected economic benefits depend on many factors: the investment costs and operating costs of the waste treatment facility, revenues, the market price of the product obtained by waste treatment etc. The investment and operating costs and the revenue also depend on the amount of treated waste. This paper presents a mathematical model for evaluation of cost-effectiveness in the waste treatment technique with energy recovery depending on the amount of waste, i. e. evaluation the minimum amount of waste to be treated for a cost-effective waste treatment technique with energy recovery. To develop the mathematical model, a socio-economic analysis was used. The model is applied to calculate the lower limit of cost-effectiveness in the waste treatment techniques with energy recovery: incineration and anaerobic digestion, in the city of Nis, Serbia, as a case study. The obtained results show that the amount of waste currently generated in the city of Nis is not sufficient for the cost-effective incineration treatment, but with the currently available amount of waste, anaerobic digestion is the waste treatment that can be operated without losses in the city of Nis.

Efficient Processing

In the recent years, speed of urbanization and industrialization had increased quickly and strongly which continued to increase in the next years. It has brought about pressure on the environment and community. We have many difficulties, existence which need to solve as treatment waste water and air pollution, solid waste is also a big challenge, it is menace to the environment and health of community. Efficient processing of municipal solid waste is a effective solution. We need criterions to assessment. From the practical requirement, research had made criterions to assess the effectiveness of composting technology, waste inceration technology, sanitary landfill technology. The results of the application of this criterion (application to assess the effectiveness of the treatment technology of municipal solid waste - in case research in North West Solid Waste Treatment Complex at 3 business) showed reasonable, effective which raise process efficiency, improvement and perfection of the treatment technology of municipal solid waste. Criterions can apply with business, government in treatment municipal solid waste.
