“…Hence, the active dumping site should be closed by a proper control with liner provision. In the capped dumping site (landfill) there is a provision for leachate collection system and gas monitoring system (Allen 2001). The provision of liner in the landfill protects the surrounding environment including soil, groundwater and surface water by containing leachate generated within the landfill, controlling ingress of ground water and assisting in the control of the migration of landfill gas (Koerner and Soong 2000).…”

The concentration of heavy metals was studied in the soil samples collected around the municipal solid waste (MSW) open dumpsite, Ariyamangalam, Tiruchirappalli, Tamilnadu to understand the heavy metal contamination due to leachate migration from an open dumping site. The dump site receives approximately 400-470 tonnes of municipal solid waste. Solid waste characterization was carried out for the fresh and old municipal solid waste to know the basic composition of solid waste which is dumped in the dumping site. The heavy metal concentration in the municipal solid waste fine fraction and soil samples were analyzed. The heavy metal concentration in the collected soil sample was found in the following order:The presence of heavy metals in soil sample indicates that there is appreciable contamination of the soil by leachate migration from an open dumping site. However, these pollutants species will continuously migrated and attenuated through the soil strata and after certain period of time they might contaminate the groundwater system if there is no action to be taken to prevent this phenomenon.

“…Within the RDF fraction dominate the components such as paper, plastic, etc. Disposing the RDF to the landfill does not significantly contribute to reducing the volume of waste on the landfill [8]. However, when the RDF is burned that volume is reduced by 95 % [8].…”

Subject rewiewMechanical Biological Treatment (MBT) of waste represents a series of mechanical and biological processes which have the purpose to reduce the amount of waste that is placed on a landfill. In accordance to the 'hierarchy of waste' defined by the EU Waste Framework Directive, waste disposal to landfill represents the least desirable option.Considering the MBT process, the input component is a Municipal Solid Waste (MSW) and output components consist of Refuse Derived Fuel (RDF), compost and possibly the materials suitable for recycling.The quality of output components depends on the input waste composition.More efficient primary waste separation decreases capacity and complexity of MBT facilities.RDF offers possibility of energy recovery from the part of such separated fractions.MBT technology does not solve the problem of harmful substances residual in MSW narrowing the application of compost obtained by the biological treatment and requiring additional treatment of flue gases from RDF combustion. Comparison of the composition of untreated MSW and RDF obtained by the MBT process is also presented in the paper. Keywords: compost; MBT; RDF/SRF; waste hierarchy Fleksibilnost MBO postrojenjaPregledni članak Mehaničko biološka obrada otpada (MBO) predstavlja niz mehaničkih i bioloških postupaka koji imaju za svrhu smanjiti količinu otpada koji se odlaže na odlagalište što prema "hijerarhiji otpada" definiranoj Direktivom o otpadu (Waste Framework Directive) Europske Unije predstavlja najmanje poželjnu opciju zbrinjavanja otpada. Ulazna komponenta u MBO proces je kruti komunalni otpad (MSW), a izlazne komponente čine RDF gorivo, kompost i eventualno materijali pogodni za recikliranje. Kvaliteta izlaznih komponenti ovisi o ulaznom sastavu otpada. Učinkovito primarno razdvajanje otpada smanjuje potrebu za MBO kapacitetima. RDF nudi mogućnost energetske oporabe dijela izdvojenih frakcija. MBO tehnologije ne rješavaju problem štetnih tvari zaostalih u MSW, koje sužavaju primjenu komposta dobivenog biološkom obradom, a kod spaljivanja RDF-a zahtijevaju dodatne postupke obrade dimnih plinova. U radu je dana usporedba sastava neobrađenog MSW-a i RDF-a dobivenog odabranim MBO postupkom.

“…Although in the future, waste minimization and recycling programs will reduce waste volumes, and other waste treatment options may be developed, at the end of the day landfills will still be required to accommodate residual waste [1].…”

This paper presents, firstly, the influence of the geometry of a slope in the safety factor (SF). In order to do this, the SF is compared among three types of slopes: with berms every 7 m high and a dam at the toe, without berms and with a dam at the toe, and without berms nor dams. It was observed that, for the same inclination, the berms do not significantly influence the stability. However, the construction of an earth dam at the base increases safety, especially with little height and slope in waste with poor mechanical properties. On the other hand, a set of diagrams to learn, quickly and easily, the safety factor of a landfill slope has been developed. Thus, this set of diagrams allows calculations from the SF height (from 17 to 80 m) and slope inclination (from 45° to 14°) with values of effective cohesion of the waste (C'o) from 1 to 3 t/m 2 and effective friction angle (Φ') of 10° to 25°.
