Fashion today is about an obsession with outward image and appearance. Though the door delivery of goods is very useful for modern consumers, it has given rise to some serious environmental challenges due to excessive usage of plastics. To pack the clothes ordered online needs a whole leap of plastic wrap, bubble sheet, thermocol sheet and the list of packaging waste is endless. From polybag to collar band, plastic has a wide range of use in the packaging segment, though recycling and reusing these materials are difficult. Products like corrugated bubble sheet, green wrap, indented kraft paper can be intensive as eco-friendly alternatives for this ecological damage. Though there is room for sustainable modules in the fashion industry, there must be companies and people willing to take up the new ideals. This paper reviews plastic consumption in packaging and its environmental annoyance and the alternatives identified by some fashion brands..

During Leather Processing, Skin Fleshing Wastes (SFW) are usually disposed of in an open area which creates toxic hazards. In this study, (SFW) from tanneries have been hydrolyzed using two alkalis Potassium hydroxide ( 2g/ 100g of SFW ) and Sodium hydroxide ( 4g/100g of SFW) with a sufficient amount of water at 2300 F in Autoclave for two hours. Three resultant fractions fats and oil (approximately 240 g Kg-1 ), protein (approximately 554 g Kg-1 ) and sludge containing a high amount of ashes (approximately 900 g Kg-1 ) were successfully isolated respectively. The yield of fractions was calculated on the wet weight of SFW used after the removal of lime using ammonium sulphate. In this study, the isolated third fraction Fleshing Sludge (FS) from the hydrolyzed fleshing wastes used fertilizer on the six different plants on growth commonly named Ghobi, Cran Dola, Patunia, Placus, Dentist and Dalia. The observations were taken during 30 days of incubation, at the usual temperature. The application of FS in plants observed that growth was enhanced in significant proportion as compare to reference plants supplemented with commercial fertilizer except in the Ghobi sample PS1 which shows some phytotoxicity confirmed by leaf yellowing. The results revealed that the applied sludge has no adverse effect on the growth of other experimental plants. Results were taken by measuring plants according to standard methods
在皮革加工过程中，剥皮废物(SFW)通常被处理在一个产生有毒危害的开放区域。在本研究中，用氢氧化钾(2g/ 100g SFW)和氢氧化钠(4g/100g SFW)两种碱在2300f的高压灭菌器中水解(SFW)两小时。成功分离出三种产物，分别为脂肪和油(约240 g Kg-1)、蛋白质(约554 g Kg-1)和含有大量灰烬的污泥(约900 g Kg-1)。用硫酸铵脱除石灰后用sfww的湿重计算馏分收率。在本研究中，从水解肉化废物中分离出的肉化污泥(FS)的第三部分用于六种不同的植物上，这些植物通常被称为Ghobi, Cran Dola,Patunia, Placus, Dentist和Dalia。观察是在30天的孵育期间，在正常温度下进行的。除Ghobi样品PS1表现出一定的植物毒性(由叶片变黄证实)外，施用FS的植物与添加了商业肥料的对照植物相比，生长有显著的提高。结果表明，施用的污泥对其他实验植物的生长没有不利影响。结果是根据标准方法测定植株

The important component of personal protective equipment is a mask. Mask is more important in a pandemic because it safeguards our life by stopping the spreading of the Coronavirus by entrapping the droplets from the corona affected person to enter into the wearer’s nose. Many types of masks are available such as non-woven mask, reusable mask, N95 mask and cloth mask etc. The majority of commercial masks are non-woven masks which are made up of polypropylene fibre. The main drawback of non-woven masks is their discomfort due to lack of breathability. This problem is solved by utilizing natural fibres as one of the raw material in non-woven and using them in the mask. Bamboo fibre is a natural celluloid fibre having good comfort properties with antimicrobial properties. Hence an attempt is made in this review article to examine the important properties of bamboo fibre and to evaluate its potential as a protective barrier material in non-woven face masks.

: The natural fibers prepared from plant waste have parameters like fiber strength, length, and chemical composition which are suitable to fabric and the fibers into nonwoven. The selected plants were identified from their botanical names by comparing the collected samples with those of known identity in the herbarium of a botanical survey in India with their names as Sesbania grandiflora, Mutingia Calabura, and Bauhinia Purpurea. A novel Portable multi-fibre decorticator machine was fabricated and used to extract the fibers from the plant stem and barks. The extracted fibers are done physical characterization and their properties are investigated. The extracted fibers are blended with other natural fibers like jute and flax in appropriate proportions 45:45:10 and nonwoven fabrics were prepared by the needle-punching method. Three and four-layer nonwovens are produced using a needle punching machine. The developed nonwovens are tested using standard apparatus and the effect of natural fibers in areal density, thickness; bulk density, porosity, and air permeability are analyzed. In addition, thermal conductivity and sound absorption behaviour are also investigated. The sound absorption property increases concerning areal density and fabric thickness. The thermal conductivity increased by increasing the fiber layer in the fabric to evaluate its potential as a protective barrier material in non-woven face masks.
