Evolution of a collection scheme in 15 years: quality and efficiency in the North Italian experience© Wasteconsult International (6/2010)
When considering organic waste collection, quality is always a critical aspect. This work summarizes the experience of the Northern Italian waste management public consortium TV3 (Treviso Tre), which has been running residential source separation schemes of organic waste since the mid 1990s. Today the mature separate collection scheme shows contamination rates of less than 2% in the collected feedstock.
Estimating and forecasting on the production values of recycling waste containers in Taiwan© Aristotle University of Thessaloniki (6/2009)
Recycling waste containers is a global issue for environmental protection, while production value is one of the indicators to measure the economic efficiency for the recycling. This study conducts regression and time series analysis, and integrates ratio estimation with input-output table to provide an alternative way to forecast production values step by step.
SOLUTIONS TO IMPROVE THE MSW COLLECTION IN LOUGA CITY, SENEGAL© IWWG International Waste Working Group (10/2007)
This paper presents the results of a study conducted by CeTAmb, with the collaboration of two Italian NGOs (CESVI and CISV) and the local Municipality, in order to identify actions that could be adopted to improve the current MSW management in Louga. Louga (Figure 1) is a city placed in the northern part of Senegal, 200 km far from Dakar. Its territory spreads on a wide sandy plain whose altitude varies between 30 and 40 m above sea level. The region is characterised by a sahelian climate with a raining season (annual precipitation rate is about 300 mm/y) between July and September and a dry season from October to June.
NUTRIENT COMPOSITION OF POULTRY LITTER AS INFLUENCED BY COMPOSTING UNDER VARIOUS STORAGE CONDITIONS© IWWG International Waste Working Group (10/2007)
Poultry litter is a waste product of commercial poultry farms. It is a mixture of poultry droppings and bedding materials, such as sawdust and rice-hull. Owing to its high macronutrients content and significant amounts of secondary and micronutrients, poultry litter is considered to be the most valuable organic manure for fertilizing purpose. In addition to benefits that poultry litter provides to crop production in the form of nutrients, this organic manure can build soil organic matter reserves which benefits crop production, and structural stability (Moore Jr. et al., 1995). In Pakistan, with the development of poultry industry, large quantities of poultry litter are produced. This litter is being used as fertilizer by the farmers and is considered as a better organic fertilizer than the farmyard manure. Thus recycling of organic waste in agriculture adds much needed organic and mineral matter to the soil (Khan et al., 2003).
DIAGNOSIS OF THE SEPARATE WASTE COLLECTION OPTIMIZATION. SANTANDER (SPAIN) CASE STUDY.© IWWG International Waste Working Group (10/2007)
Santander is one of the most important tourist cities of northern Spain, with an estimated population of 185.000 inhabitants. As a modern European city, Santander performs municipal solid waste management satisfactorily, and has implemented a separate waste collection system since 2003. Currently it has an average production of municipal solid waste of 1.14 kilograms per inhabitant per day, with a recycling rate of 39.9, 22.7 and 30.0 per cent of paper and cardboard, packaging, and glass respectively.

THE CITY OF STAVANGER BRINGS THE HOUSEHOLD WASTE UNDERGROUND© IWWG International Waste Working Group (10/2007)
Each inhabitant in Stavanger produces an annual amount of about 430 kg of household waste (see table 1). More than 80% of this is collected at the household from a 3-bin system. In addition hazardous waste and smaller WEEE-goods are collected from each household twice a year. Almost all other types of waste can be delivered to one of the 48 unmanned recycling points or at the manned recycling station. The level of source separation amounts to the quite high portion of 65%. The separated waste is mainly recycled into new materials, including compost. (Session A6: Waste collection)
