2. 1. The Prima Porta Garden Archaeological Project. Terra sigillata from the Villa of Livia, Rome. Consumption and discard in the early Principate

   Author : Allan Klynne; Philip Kenrick; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Classical archaeology and ancient history; Villa of Livia; terra sigillata; Central Italian sigillata; fabrics; trade; consumption; discard; refuse; formation processes; chronology.; Antikens kultur och samhällsliv; Classical archaeology and ancient history; Antikens kultur och samhälle; Classical Archaeology and Ancient History; antikens kultur och samhällsliv;

   Abstract : 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. READ MORE

4. 2. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish

   Author : Erik Noaksson; Lennart Balk; Louis J. Guillette Jr; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fiskar; miljögifter; Toxicology; Toxikologi;

   Abstract : 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. READ MORE

5. 3. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

   Author : Evelina Brännvall; Britt-Marie Steenari; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

   Abstract : 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. READ MORE

6. 4. Polygeneration District Heating and Cooling Systems Based on Renewable Resources

   Author : Natalia Kabalina; Mário Manuel Gonçalves Costa; Weihong Yang; Andrew Martin; Luis Barreiros Martins; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating and cooling systems; polygeneration; refuse derived fuel; municipal solid waste; gasification.; Energy Technology; Energiteknik;

   Abstract : 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).

7. 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

   Author : Anita Pettersson; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge;

   Abstract : 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.
