1. The Prima Porta Garden Archaeological Project. Terra sigillata from the Villa of Livia, Rome. Consumption and discard in the early Principate
Sammanfattning : This study examines a corpus of Italian sigillata from the Villa of Livia outside Rome, and presents the excavations during which it was found. Most of the material stems from archaeologically secure contexts, a refuse tip and dump dating to the late Augustan and Neronian periods respectively. LÄS MER
2. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish
Sammanfattning : The global economy is driven by the consumption of goods and materials. Used products are often deposited on refuse dumps, making them potential point sources for all man-made chemicals. Water soaking through landfill waste results in a wastewater termed leachate. LÄS MER
3. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes
Sammanfattning : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. LÄS MER
4. Polygeneration District Heating and Cooling Systems Based on Renewable Resources
Sammanfattning : Traditional district heating (DH) and district heating and cooling (DHC) systems have to address two principal challenges: phase-out of fossil fuels in favor of renewables; and profit instability related to declines in heating and cooling demands along with electricity price fluctuations. These obstacles can be overcome at once through upgrading these systems to a polygeneration concept by means of a retrofitted air-steam gasifier and gas upgrading equipment, enabling the use of renewable feedstocks such as refuse derived fuel (RDF) and municipal solid waste (MSW).

5. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective
Sammanfattning : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.
