By causing high amounts of household food waste, German households contribute significantly to serious global threats for the environment. Unfortunately, current information campaigns, conducted by several food waste-prevention initiatives, often lack in recipient’s perceived relevance of provided recommendations on how to prevent household food waste by improving the performance of relevant fo...

anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.this technology is superior to the landfilling and also the aerobic composting. the aim of the present study was to examine whether the effluent volatile fatty acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

An estimated 30 percent of the global food supply is lost or wasted, as is about 40 percent of the US food supply. There are valuable synergies between efforts to reduce food loss and waste and those promoting public health. To demonstrate the potential impact of building upon these synergies, we present an analysis of policies and interventions addressing food loss and waste, food security, fo...

We estimate models of consumer food waste awareness and attitudes using responses from a national survey of U.S. residents. Our models are interpreted through the lens of several theories that describe how pro-social behaviors relate to awareness, attitudes and opinions. Our analysis of patterns among respondents' food waste attitudes yields a model with three principal components: one that rep...

INTRODUCTION: STUDYING FOOD This position paper seeks to uncover and understand a range of everyday behaviours associated with food shopping, preparation, consumption and waste as a precursor to design. How food is purchased, prepared, consumed and its waste disposed of is of growing interest for those concerned with sustainability and ‘carbon footprint’ [2, 3]. This topic provides interesting ...

Introduction During this research project, we attempted to identify and overcome barriers and resistance to the establishment of organic waste (leaf and yard waste and food waste) collection and diversion programs within public and private institutions in the region that generate large amounts of organic wastes. As only 2.4% of food waste (EPA 1997) is recovered or recycled, there is 97.6% of f...

BACKGROUND Waste is currently a major problem in the world, both in the developing and the developed countries. Efficient utilization of food waste for fuel and chemical production can positively influence both the energy and environmental sustainability. This study investigated using food waste to produce acetone, butanol, and ethanol (ABE) by Clostridium beijerinckii P260. RESULTS In contro...

• Pilot scale validation of food waste digestion coupled to photosynthetic upgrading. Biogas production 68 ± 8 L d -1 at a loading rate 0.86 g VS (35 °C, 1 bar) Maximum recovery efficiencies 60 and 100% were achieved for TN TP. CO 2 removal 90% in biomethane. CH 4 concentrations > 93% This work aimed integrating the anaerobic (FW) with biogas upgrading pilot order obtain high quality biomethane...

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...

This study focuses on food waste generated by households in four Nordic countries: Finland, Denmark, Norway, and Sweden. Based on existing literature we present (A) comparable data on amounts and monetary value of food waste; (B) explanations for food waste at household level; (C) a number of public and private initiatives at national levels aiming to reduce food waste; and (D) a discussion of ...
