In the departments of Attika and Viotia there are about 1,100 industries. The total amount of produced waste from the above mentioned branches is 20 × 106 t/year, 600,000t of which contain toxic substances. By contract from October 1st, 1992 between the Ministry of the Environment, Regional Planning and Public Works and three collaborating offices (among them the office of C. Malliaros) has been assigned to the latter, the realisation of a study of the management of toxic waste (liquid) and sludges, in the Departments of Attika and Viotia. The study presented in this paper investigates the following: - collection and evaluation of data and estimation of the hydraulic and pollution loads - classification of industries according to sewage facilities - further possibilities for changes of improvements in the production process of the industrial branches for the reduction of pollution and representation of these industries on maps - proposals for the collection and transport of the liquid toxic waste and sludges - pre-treatment at the source and disposal of the liquid waste and sludges - presentation of administrative and legislative regulations - forming a policy for the management and monitoring of this waste - technical and financial evaluation and investigation of the alternative methods of treatment - suggestions for the development of the area concerning the activities and the expenses at various levels.

Abstract This case study summarizes the current knowledge in Finland on the efficiency of constructed wetlands to improve water quality at the same time providing multiple benefits. The efficiency is highly dependent on the wetland’s relative size compared to the upstream catchment area, and on the amount of agricultural land in the upstream catchment. The case study analyses the incentives designed to motivate landowners to construct wetlands in Finland such as the non-productive investment support and the agri-environment payment support for wetland management. Farmers think that the support system is heavy and bureaucratic, and thus the target number of new constructed wetlands is far from being met. Individual projects have been more successful in wetland construction than the official support system. General wetland plans drafted for hotspot areas is an example of enabling factors and strict eligibility rules form one of the barriers of wetland construction identified in this case study. In spite of the criticism of the current wetland incentives, a support system for wetland construction is needed. One option would be to give regional authorities more freedom to select priority areas according to e.g. River Basin Management Plans.

Farm Business

The growth of the dairy industry in Indonesia is expected to be an attraction for the local farmers. The increasing number of breeders will have a negative impact on the increase of waste generated.Waste from the farm business can be a solid waste, gas and liquid waste. Animal husbandary waste can be processed to produce biogas as an energy alternative to oil burner and premium drive electricgenerators. From the measurement of CH4 content ranged from (56.67 - 62.8 %), while the CO2 content ranged between (36.36 - 42.64 %). This value is between methane and carbon dioxide content of the theoretical limit. Gasbio volume generated during the 24 hours ranged of 4.218 - 6.198M3, or the average of the gas produced as much: 5,096 M3 per day. Electricity generated = 3.822 kWh. Electricity power genset of 500 watt can burn for 7 hours. The results of laboratory analysis of sludge solids can be seen that the C / N ratio is still relatively high at 42.6, whereas the C / N ratio, which allowed ranged of 15-25. The C value is very high due to the organic composting process is too short, the element N is very low because the nitrogen is still in the complex chain that required the administration of N fastening bacteria such as : Azotobacter, Azotomonas, Pseudomonas.Keywords: cattle manure, biogas, energy listrk, compostAbstrakPertumbuhan industri susu olahan di Indonesia diharapkan akan mampu menjadi daya tarik bagi peternak lokal. Meningkatnya jumlah peternak akan berdampak negatif terhadap meningkatkanlimbah yang dihasilkan. Limbah dari usaha peternakan tersebut dapat berupa limbah padat, gas dan limbah cair. Limbah peternakana dapat diproses untuk menghasilkan biogas sebagai energi alternatif pengganti minyak kompor dan premium menggerakan generator listrik. Dari hasil pengukuran kandungan CH4 berkisar antara (56,67 – 62.8%), sedang kandungan CO2 berkisar antara (36.36 – 42,64%). Nilai tersebut berada diantara kandungan metan dan karbon dioksida pada batas secara teori. Volume gasbio yang dihasilkan selama 24 jam berkisar antara (4,218 - 6,198) M3,atau rata-rata gas yang dihasilkan sebanyak : 5,096 M3 perhari. Listrik yang dihasilkan = 3,822 kWh. Genset dengan daya 500 Watt maka listrik bisa menyala selama 7 jam. Dari hasil analisislaboratorium terhadap padatan sludge dapat diketahui bahwa C/N ratio tergolong masih tinggi yaitu 42,6, padahal C/N ratio yang diizinkan berkisar antara 15 – 25. Hal ini disebabkan karena Corganiknya sangat tinggi akibat proses komposing masih terlalu singkat, unsur N sangat rendah karena nitrogen masih dalam rantai yang kompleks sehingga diperlukan pemberian bakteripenambat N, diantaranya adalah: bakteri Azotobacter, Azotomonas, Pseudomonas.

Design of cost-effective Mass Exchange Networks (MENs) that involves mass integration can help to minimize the amount of mass separating agent (MSA) purchased, waste MSA generated by industries, reduce operating costs and mitigate environmental issues associated with MSA disposal. Design of MENs can be done using graphical and numerical methods, as well as using mathematical modelling. This work describes a new approach for simultaneous targeting and design of MENs in which both targeting and network design stage can be solved in a single template, in order to overcome the limitation of graphical tools such as MENs Composite Curves (CCs) and Grid Diagram. CCs cannot completely map individual rich and lean process streams, or process and utility streams. On the other hand, the numerical technique known as Composition Interval Table (CIT) failed to show individual rich and lean stream mass cascades and cannot be used for MENs design. The newly developed numerical approach in this paper employs the Segregated Composition Interval Table (SECIT) to simultaneously locate mass pinch point, determine the minimum utility targets and perform SECIT Mass Allocation (SMA) that can be used to visualize in SECIT Network Diagram (SND).This work can be applied in industries to minimize liquid waste and reduce environmental pollution A case study is presented to demonstrate the validity and advantages of the proposed approach. This paper also shows that SECIT and SND can be a vital combination of numerical and graphical visualization tools for targeting and design of complex MENs.
