Abstract

Purpose

The purpose of this paper is to investigate the implications of the China’s rising meat demand and industrialization of the livestock sector for the vegetable oil market.

Design/methodology/approach

An equilibrium displacement model is constructed to analyze the interactions between meat consumption and vegetable oil market through the development of livestock sector modernization. Parameters derived from the 2006 to 2009 data are first used to produce the counterfactual growth rate of the non-soybean vegetable oil to validate the model. Then the authors use the second set of parameters derived from the 2010 to 2013 data to forecast the changes in the vegetable oil market in China.

Findings

Soybean oil, as a co-product of soybean processing, tends to crowd out other vegetable oils. In particular, the authors find that the market for non-soybean vegetable oils may shrink as long as the rapid industrialization pace above 10 percent within China’s livestock sector continues. Although their production takes up only 8.5 percent of all agricultural lands in China, oil crops remain as important cash crops for farmers contributing over 10 percent to the overall farm income in some provinces. The authors’ analysis suggests that stakeholders in these regions should closely monitor the structural changes within the livestock sector and consider the information for crop selection.

Originality/value

The authors’ analysis contributes to the literature on China’s meat demand by highlighting its implications for other agricultural markets involved in the food system.

Abstract

The level and structure of protection from tariff and non‐tariff measures confronted by developing country exports of oilseeds, vegetable oils, and related products are examined to assess the gains available to these countries through further rounds of trade liberalisation. Although developing country exporters of these products can expect only limited benefits from a removal of tariffs by major developed market economy country (DMEC) importers, considerable gains could be realised by removing the relatively higher tariff rates imposed by the developing countries, and by removing the many non‐tariff measures which developing countries and DMECs use as well.

Abstract

Purpose

The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process.

Design/methodology/approach

According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated.

Findings

The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features.

Originality/value

There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.

Abstract

Purpose

The purpose of this paper is to investigate the performance of four cutting oils, two different vegetable‐based cutting fluids developed from refined sunflower oil and two commercial types (semi‐synthetic and mineral), for surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool.

Design/methodology/approach

L9 (33) orthogonal array was used for the experiment plan. Spindle speed, feed rate and drilling depth were considered as machining parameters.

Findings

Results were evaluated statistically. Mathematical models based on cutting parameters were obtained from regression analyses to predict surface roughness. ANOVA was used to determine the effect of the cutting parameters on the surface roughness. The performance results were found to be better for vegetable‐based cutting oils than that of commercial ones.

Originality/value

The paper reports on the use of refined sunflower oil in drilling stainless steel.

Abstract

Recently, much effort has been focused on research and development of new types of lubricating oil additives to reduce wear and friction in the tribological systems. It has been noted that the use of additives to improve the lubricating capacity and durability of oil plays an important role in the wear and friction process of materials. Due to the environmental problems, many researchers are embarking on the viability of the vegetable‐based lubricants. In this article a critical review has been made on vegetable‐based lubricant additives with specific properties and application. This article explains the advantages and manufacturing processes of vegetable‐based oils, which will give a better understanding of using biodegradable lubricating oil additives. A case study on palm oil methyl ester as an additive has been presented in this paper.

Abstract

Outlines some of the reasons behind the development of vegetable oil cheese and critically questions the whole basis and need for such cheese‐type or substitute products. Evaluates two of these new products and compares them with mild and low‐fat Cheddar cheese by using a semi‐trained sensory panel. Finds no significant differences between the appearance of the cheeses but finds differences for texture and flavour. Finds the vegetable oil cheeses to have a flavour similar to mild Cheddar, while the product made with sunflower oil has a soft and crumbly texture compared with that of cheese made from rapeseed oil.

Abstract

Purpose

This paper aims to provide a detailed review of various cutting fluids (CFs).

Design/methodology/approach

Friction and wear are inevitable in machine parts in motion. The industrial sector uses various kinds of lubricants, which include engine oils, CFs, hydraulic fluids, greases, etc. to control friction and wear. The main purpose of using CF is to remove heat produced during machining and to reduce cutting forces, tool wear and energy associated with it. Thus, it increases the productivity and quality of the manufacturing process. But more than 80% of the CFs used in the industries now are mineral oil-based. These mineral oils and additives are highly undesirable because of their toxicity, nonbiodegradability, pollution and ecological problems. Hence, these petroleum-based oils in the lubrication system can be substituted with alternatives such as vegetable-based CF. Several studies are being conducted in the field of eco-friendly CFs. Because of the variance in fatty acid profile and availability, the selection of vegetable oils (VOs) is another problem faced nowadays. The present study is focused on bio-based oils and many eco-friendly additives. Various machining processes and comparisons relating to the same have also been made. The aim is to minimize the use of mineral oil and thereby introduce sustainability in production.

Findings

In this present study, bio-based oils, additives and various characteristic behavior of them in machining are being discussed. The VOs are found to be a potential base oil for industrial CFs.

Originality/value

This paper describes the importance of sustainable CFs.

Abstract

Purpose

This study aims to investigate the behavior of vegetable oil with two additives. Base oil’s tribological qualities can be improved with the help of several additions. In the present investigation, soybean oil is served as the foundational oil due to its eco-friendliness and status as a vegetable oil with two additives, named polytetrafluoroethylene (PTFE) and molybdenum disulfide (MoS2).

Design/methodology/approach

As additives, PTFE and MoS2 are used; PTFE is renowned for its anti-friction (AF) properties, while MoS2 is a solid lubricant with anti-wear (AW) properties. This investigation examines the synergistic impact of AF and AW additions in vegetable oil. The lubricity of the base oil is measured by using a four-ball tester, and the wear properties of the oil at different additive amounts are determined by using a universal tribometer.

Findings

PTFE (at 5 Wt.%) and MoS2 (at 1 Wt.%) were found to improve the tribological performance of the base oil. The weld load is significantly increased when 5 Wt.% of PTFE + MoS2 is added to the base oil.

Originality/value

A better tribological characteristic can be achieved by combining additives that amount to less than 1% of the base oil. In experiments with highly concentrated MoS2, the adequate pressure improved dramatically, but the lubricant’s tribological characteristics did not.
