In the United States, food was...

The modern food system has evolved into one with highly inefficient activities, producing waste at each step of the food pathway from growing to consumption and disposal. The present challenge is to improve recyclability in the food system as a fundamental need for food and health security. This paper develops a methodological approach for a Food Recycling Index (FRI) as a tool to assess recycl...

Information on food waste disposal and on recycling methods and recycled amounts is reported. Data were obtained from a mail and phone survey of all licensed food establishments in Hawaii conducted in 2004 and 2005. Of 8253 licensed food establishments, 5033 completed surveys. It was found that relationships exist between food establishment size (measured by the number of meals served per day o...

UNLABELLED Poor solid waste management is among the major challenges facing urban slums in developing countries including Uganda. Understanding community concerns and willingness towards involvement in solid waste management improvement initiatives is critical for informing interventions in slums. METHODS We used a cross-sectional study to collect quantitative data from 435 residents in two u...

Recognising that approximately one third or more of food is lost or wasted globally every year, this represents a significant challenge to food security. At the same time, however, the reduction of this waste/loss represents a major opportunity to strengthen food security and economic and social development. Yet various fundamental obstacles exist that hinder actions to tackle food waste and lo...

Cattle slurry and card packaging were used to improve the operational stability of food waste digestion, with the aim of reducing digestate total ammoniacal nitrogen concentrations compared to food waste only. Use of cattle slurry could have major environmental benefits through reducing greenhouse gas emissions associated with current management practices; whilst card packaging is closely linke...

The environmental performance of industrial anaerobic digestion (AD), pyrolysis, and integrated system (AD sequence with pyrolysis) on food waste treatment were evaluated using life cycle assessment. The integrated treatment system indicated similar environmental benefits to AD with the highest benefits in climate change and water depletion in addition to the increased energy generation potenti...

The current work focuses on the generating bio-gas from food waste produced by Mahendra Engineering College Canteen using anaerobic digestion process. Attempts have been made to optimize various parameters in order to determine the most favorable recipe for maximum biogas production from the digested food waste. The biogas yields have been determined using batch anaerobic thermophilic digestion...

Treatment of domestic waste is generally carried out by activated sludge process. The waste solid sludge can be treated by various aerobic and anaerobic treatment processes. Aerobic treatment methods need space and time. Anaerobic treatments have advantages such as space utilization and production of fuel gases such as methane. Up flow anaerobic sludge digester or fluidized bed digester can be ...

Quality of school meals is one of the major concerns of governments and international organizations worldwide. This study aims to evaluate nutritional compliance of meals served at a Portuguese primary school considering the portions stated by Portuguese Education Ministry. To evaluate adequacy of portions served, weighing of all meal components offered to students and leftovers was performed d...
