Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim

Florin C MIHAI

Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper aims to analyse the transition from traditional waste management systems to an integrated system at national, regional and local scale. Assessment of landfills location based on buffer analysis (using GIS techniques) is made according to the proximity of five critical factors (CF) such as: residential area, industry & commercial units, agricultural lands, rivers & …

Landfills As Anthropogenic Landforms In Urban Environment From Neamţ County., Florin C. Mihai, Liviu Apostol, Adrian Ursu, Pavel Ichim

Florin C MIHAI

Landfills are the most common and easiest methods to dispose the municipal waste in Romania and still prevails in current waste management options. This type of critical infrastructure was designed to dispose urban waste generated over years or even decades and ultimately led to create new landforms in urban landscape. On the other hand, these sites are major sources of complex pollution unfulfilling EU regulations, being scheduled to be closed. This paper aims to analyze landfills as anthropogenic landforms by applying GIS techniques emphasizing them in a geographical context and not only in situ. The location of these sites usually …

Improper Household Waste Disposal In Rural Territory.Case Study: Neamt County, Florin C. Mihai

Florin C MIHAI

Open dumping of waste generated and uncollected is the most common option in waste management schemes from rural areas. Lack of sanitation services or rudimentary waste management systems favored this practice. This paper proposes a method to estimate the amounts of household waste uncontrolled disposed at local administrative unit level (commune) for 2003 and 2010. Based on estimating the amounts of waste generated and uncollected are introduced new indicators in the quantitative analysis taking into account the household waste composition, individual composting of biodegradable waste or recyclable waste from households for a more proper assessment of waste disposed. Usually household …

Florin C MIHAI

Inadequate waste management leads to many environmental issues and the adoption of an efficient and sustainable waste management has become a priority objective of the EU. However, besides the demographic factors, the various socio-economic and geographical conditions of this complex space lead to major disparities in municipal waste management between North and South, East and West. This paper aims to do a spatial-temporal analysis of the Eurostat indicators using ascending hierarchical cluster analysis that divides the member states into five typological classes. The resulted maps highlight territorial disparities among Member States on municipal waste management and also reveal the evolution …

The Process Of Closing Down Rural Landfills Case Study : Neamț County, Liviu Apostol, Florin C. Mihai

Florin C MIHAI

Landfilling is the main method for municipal waste disposal in Romania. Access to sanitation services are limited on rural territory and that leads to uncontrolled waste disposal with negative implications on the geosystem. Implementation of EU acquis on waste disposal from rural areas requires local authorities to close the landfills by July 16, 2009 . Following this deadline, municipalities are obliged to provide waste collection and transportation to the existing urban landfills. Under these conditions,this article is proposing a territorial review of closing and rehabilitation of rural landfills from Neamt county. Also, this paper analyzed the existing environmental dysfunctions supported …
