Recycling involves processing used materials like glass, paper, metal, plastic, and textiles into new products in order to reduce waste, decrease consumption of raw materials, lower energy usage and greenhouse gas emissions, and cut down on air and water pollution. Paper recycling recovers waste paper to make new paper products from mill broke, pre-consumer waste, or post-consumer waste. Metal recycling reuses old metal like aluminum and steel to manufacture new items using 95% less energy than creating products from raw materials. Plastic recycling recovers scrap or waste plastics and transforms them, sometimes completely changing their form, into useful products like plastic chairs made from recycled soft drink bottles.
Paper recycling is the process of converting waste paper into new paper products. There are three categories of paper that can be used: mill broke, pre-consumer waste, and post-consumer waste. The recycling process involves collection, transportation, storage, pulping, screening, cleaning, deinking, refining, papermaking, and conversion into new products. Recycling paper provides environmental benefits such as reducing pollution, saving trees and landfill space, and conserving energy.

Plastic is a lightweight, durable and versatile material that can be made into many different products. Every year, a major part of plastic production is used to make disposable packaging that is thrown away soon after manufacture.
This poster describes the affects of plastic used plastic goods that do not biodegrade naturally on environment and how plastic recycling can play a great role in playing the savior on the case.
Plastic bags are a better environmental choice than paper bags. While plastic bags are often criticized for taking hundreds of years to degrade in landfills, the production process for paper bags requires cutting down trees, transporting timber, and emits harmful pollutants. Paper bag recycling also uses many chemicals. Plastic bags are made from a byproduct of oil refining and the production process uses less energy and resources. Plastic bags are also reused more often than expected and new biodegradable plastic bags can degrade within a few months. Overall, plastic bags have a longer service life and less environmental impact than paper bags.

Recycling transforms used materials into new products in order to reduce waste and preserve the environment. Since the 1980s, waste production has increased significantly along with packaging and disposable products. Many governments now require companies to combine economic growth with environmental preservation through recycling initiatives. Common recyclable materials include glass, aluminum, paper, and plastic, and recycling these materials can significantly reduce pollution. Changing consumption habits to reduce waste and participating in separation and collection of recyclables can help the environment and generate jobs. Recycling turns materials that would otherwise be waste into reusable resources.
1) Waste plastic from sources like bottles and packaging can be used to coat aggregates that are then used in road construction. The coated aggregates improve the strength and performance of roads compared to those made only with natural materials.
2) Plastic waste is separated, cleaned, shredded, and used to coat hot aggregates at a mixing plant. The coated aggregates are then mixed with hot bitumen to form the final road construction material.
3) Roads made with plastic-coated aggregates require less bitumen, have higher strength and durability, provide a smoother ride, and help reduce environmental problems caused by plastic waste.
Between 2010 and 2019, the volume of plastic produced across the world increased by 100 million metric tons. Indeed, the variety of material characteristics, low cost and ease of plastic production has led the material to be used in a range of ways across many industries. From shopping bags to protective caps and electronic equipment, plastics have become one of the most widely used materials in the world.
Despite the advantages plastics can bring to consumers and manufacturers, the creation, use and disposal of the material has had a huge impact on the environment. From threatening marine life to changing soil composition and entering the human food chain, the dangers this material poses to the world’s health is widely recognised by consumers, governments, and the plastics industry itself.
So how are plastics manufacturers looking to improve the sustainability of their operations and is it possible to achieve environmentally friendly production?

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
