Carbon Footprint of Fruit Paste Technology

Abstract

The carbon footprint is one of the main indicators to assess the impact of human activity on the natural environment. The aim of this study was to determine the carbon footprint for the production technology of fruit paste. We selected homogenized strawberry paste because it had the largest share in production. Our study presents the methodology for calculating carbon dioxide emissions in order to assess and reduce greenhouse gas emissions generated by the given food technology. CO 2 emissions were calculated for monthly and annual production, taking into account available data on production, material balances obtained, emission data collected, and assumed indices. It has been shown that the process of cold storage is a major factor influencing the level of CO 2 emissions. Determining the carbon footprint of specific technology enables deliberate reduction of greenhouse gas emissions, which contributes to environmental protection.

The Relationship between Agricultural Carbon Emissions and Agricultural Economic Growth and Policy Recommendations of a Low-carbon Agriculture Economy

“…On the basis of some researchers' carbon emission equations [28,29], this paper has constructed an agricultural carbon emissions formula as follows: 4 , which mainly includes the CH 4 emissions caused by enteric fermentation and the discharge of CH 4 and N 2 O during livestock manure management). All the carbon sources and coefficients in this paper are from the research of Xiong Chuanhe [30].…”

“…Moreover, we used the lowest level (0.79) of the decoupling index over the past 15 years as the scenario predictions for the period 2014-30. The results show that total agricultural carbon emissions will be 145.01×10 4 …”

“…The increasing concentrations of CO 2 , N 2 O, CH 4 , and other greenhouse gases in the atmosphere constitute the most important roots of global warming [2][3][4]. Based on this background, a "low-carbon economy" with low energy consumption, low pollution, and low greenhouse gas emissions comes into being with the goal of realizing the decoupling of economic growth and greenhouse gas emissions.…”

“…The emissions of greenhouse gases in the global agricultural ecosystem accounted for 13.5% of the world's total greenhouse gas emissions [21], and the emissions of greenhouse gases in China's agricultural ecosystem accounted for about 17% of China's total carbon emissions [22], which is responsible for >20% of global agricultural GHG [21]. CH 4 and N 2 O from agriculture account for 50% and 92% of China's total CH 4 and N 2 O emissions, respectively [23]. Thus it is not scientific to neglect the agricultural carbon emissions in the study of carbon emissions, and it is not reasonable only to consider the relationship between economic growth and agricultural carbon emissions.…”

Evaluation of Opportunities to Reduce the Carbon Footprint of Fresh and Canned Pineapple Processing in Central Thailand

“…As agriculture is one of the contributors to anthropogenic emissions of GHGs, the quantification of agricultural practices is crucial for identification of more sustainable practices [8]. Several studies have evaluated and assessed a variety of agricultural crops and products by applying CF methodology, such as organic blueberry production in Chile [9], strawberry paste production [10], and winter lettuce production in the U.S. [11]. However, there is little current research information about GHG emissions in the pineapple sector, especially pineapple processing.…”
