Bjerre 7 is a modest Late Bronze Age house in Thy, Denmark. Excellent preservation and full-recovery techniques provided comprehensive evidence of farm self-sufficiency, local exchange, amber collection for trade. Spatial analyses ceramics, lithics, plant macrofossils, identified distinctive activity areas at both ends the outside. Routines are discussed refuse disposal, ceramic use everyday ac...

BACKGROUND Solid medical waste (SMW) in households is perceived to pose minimal risks to the public compared to SMW generated from healthcare facilities. While waste from healthcare facilities is subject to recommended safety measures to minimize risks to human health and the environment, similar waste in households is often untreated and co-mingled with household waste which ends up in landfil...

The proximate and ultimate analyses of 20 constitu­ ents of municipal and commercial refuse are presented, to .. gether with the calorific values. The analyses are useful o incinerator engineers as they are the basis for calcu­ Jating air requirements, flue .. gas volumes, and heat and material balances. The analyses of components of refuse permit the calculation of composite analyses of mixed ...

R efuse is collected all around the world. The following collecting methods are mentioned in the literature: bags (plastic and paper), bins (110–150 l), drums (110–210 l), twowheeled containers (80–360 l), and four-wheeled containers (300–1800 l). Over all, the job of a refuse collector can be characterised by frequent lifting, carrying, pushing, and/or pulling of heavy objects. In the Netherla...


 The increased demand for energy is impacted by the growing population. As a result, new sources must be developed to replace diminishing supplies. Waste Energy (WTE) concept that can used as an alternative recycling waste into raw materials Refuse Derived Fuel (RDF). Due their combustibility, inorganic and plastic have potential employed source RDF. In light of this discussion, RDF requi...

The typical U.S. refuse-to-energy facility utilizes a 600 psig, 750°F steam cycle. The ability to operate at higher steam pressure and temperature cycles, without incurring excessive corrosion, results in more kilowatts per ton of refuse and, hence, more economically at­ tractive projects. This paper represents the evolution of a 900 psig, 830°F refuse boiler from lower temper­ ature and pressu...

Objective To explore the process of refuse decomposition in hybrid bioreactor landfill. Methods The bioreactor landfill was operated in sequencing of facultative-anaerobic and aerobic conditions with leachate recirculation. pH, COD, and ammonia in the leachate and pH, biodegradable organic matter (BDM), and cation exchange capacity (CEC) in refuse were detected. Results CEC increased gradually ...

Techniques were evaluated for formation of a liquid inoculum from shredded municipal refuse, including chilling the refuse at 4 degrees C prior to blending and multiple washing and blending cycles. The average count of cellulolytic bacteria from six different detachment treatments was 5.1 x 10 cells per g (dry weight) of refuse with a range of 0.7 x 10 to 12.7 x 10 cells per g (dry weight). The...
