agriculture (mechanization), food industry and environment are the concepts that cannot be surveyed separately (because of their interaction). present research aimed to study tomato paste production by applying life cycle assessment. two functional unit of kg co2-eq/ kg tomato and kg co2-eq / kg paste was used. data were collected from one paste factory in alborz province and open-field tomato ...

Poultry industry is an important production system due to providing remarkable portion of the human food and protein needs. Considering the necessity of environmental protection, the amount of environmental impacts of a turkey production unit in Iran was determined using life cycle assessment method. The required information were collected through questionnaires and interviews with farm owners....

global warming and global climatic changes have attracted many concerns. the objective of this research was to examine greenhouse gas emission and its resultant global warming potential (gwp) in wheat production in gorgan, north-east of iran. to do this, six wheat fields were selected and during three consecutive growing seasons, data were gathered on input and energy use in all production prac...

the objectives of this study was to estimation of greenhouse gases (ghg) emissions and global warming in rice production and identify measures to reducing fossil energy use and greenhouse gases emissions. three rice production systems included sri, improved and conventional were studied. all activities, field operation and data in production methods and differents inputs rates were monitored an...

In modern agriculture, the energy that is consumed in every stage of production can be divided in direct (e.g. fuels and lubricants) and indirect (e.g. machinery embodied energy, materials and agrochemicals etc). This energy consumption can be examined further in environmental level as environmental impact. Environmental impact regards to the CO2 that is emitted during the production process an...

The effects of calcium chloride washings and passive or active modified atmosphere packaging (MAP) on the keeping quality of fresh-cut tomato (Lycopersicon esculentum Mill., cv. Durinta) were investigated. Fresh-cut tomatoes were washed in chlorinated water (0.7 mM) with and without CaCl2 (0.09 M). Slices were placed in plastic trays, sealed with perforated or non-polymeric films and stored at ...

Carbonization is a newly developed process that converts sewage sludge to biocoal, a type of solid biomass that can partially substitute for coal during power generation. This study presents an assessment of the environmental effects of various sewage sludge treatment processes, including carbonization, direct landfills, co-incineration with municipal solid waste, and mono-incineration in Taiwa...

Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic explorati...

In Australia, dairy cattle account for ~12% of the nation’s agricultural greenhouse-gas (GHG) emissions. Genetic selection has had a positive impact, reducingGHGemissions fromdairy systemsmainly due to increased production per cow,which has led to (1) requiring fewer cows to produce the same amount ofmilk and (2) lowering emissions per unit of milk produced (emission intensity). The objective o...
