Plastic pollution is a major global problem caused by the accumulation of plastic waste in the environment. Nearly 300 million tons of plastic are produced annually, half of which is for single-use purposes. More than 8 million tons of plastic end up in oceans each year. Plastic pollution harms wildlife and ecosystems through entanglement, ingestion, and chemical exposure. Reducing plastic usage, reusing products, and improving waste management and recycling are key to solving this growing environmental issue.
Plastic has become ubiquitous in modern life but takes a heavy toll on the environment. While plastic helps economic growth, its disposal harms wildlife and pollution from plastic is difficult to decompose and can take 1000 years. Steps need to be taken to reduce plastic use and develop greener alternatives to transition from harmful plastics. Both reducing plastic consumption and increasing recycling efforts are needed to balance environmental and economic concerns.
The document discusses plastic waste and plastic pollution as a global concern. It notes that plastic production has increased significantly worldwide but only a small percentage is recycled, with the rest becoming plastic waste that pollutes the environment. The document outlines India's significant plastic waste generation and recycling rates. It discusses the various types of plastics and their impacts, both positive and negative. The document proposes solutions like reducing single-use plastics, banning certain plastics, improving waste management practices, and developing more sustainable alternatives to address the growing plastic pollution problem.
Plastics are synthetic polymers that are durable, lightweight and inexpensive materials. However, they persist in the environment for centuries and have caused widespread pollution. Only a small percentage of plastics are recycled each year, with the rest accumulating in landfills and oceans. This poses threats to wildlife through entanglement and ingestion of plastic debris. Reducing plastic use and improving waste management strategies are needed to curb further environmental damage.
Plastics are everywhere, in our home, school, work, playground, parks, and beaches. It is such a popular material because it is flexible, lightweight, moisture resistant, and inexpensive. Even if plastics are found deep inland, they eventually find their way to the sea or ocean through rivers and streams. The global consumption of plastic was 260 million tons in 2010. It is estimated to reach 297.5 million tons by 2017.
Plastic pollution poses serious threats to both the environment and human health. Plastic waste accumulates in land and water bodies around the world, harming wildlife through entanglement and ingestion. Animals often mistake plastic for food due to its small size, which can cause starvation. Chemicals used in plastics' production and additives that leach out are linked to health issues like cancers and developmental problems in humans. Urgent action is needed to promote safer plastic alternatives and responsible waste disposal to mitigate these potential hazards.

Tannery industrial process, Waste generation, and Waste management.pptxUthaiya
The process of tanning leather involves five main steps: pre-tanning, tanning, selecting, dressing, and finishing. During tanning, chemicals are used to change the structure of leather fibers and make them more durable and resistant to bacteria and fungi. Common tanning methods include mineral tanning using chromium salts, vegetable tanning using plant materials, and oil tanning using fats. The tanning process generates significant solid and liquid waste, as up to 80% of the raw hide material is released as solid waste and processing one ton of hides produces 15,000-50,000 liters of wastewater.

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.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. 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.
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.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Plastic Types and sources.pptx
1. Plastics
a synthetic material made from a wide range of organic polymers such as
polyethylene, PVC, nylon, etc., that can be moulded into shape while
soft, and then set into a rigid or slightly elastic form.
2.
3. What is Plastic Pollution?
Plastic is a very useful material, but it is also made of hazardous substances
that can cause illness, and it is not biodegradable since it is designed to last
longer.
Plastic pollution is the accumulation of manufactured plastic goods in natural
settings that harms humans and wildlife.
One of the major contributions to climate change is plastic pollution.
Plastic is nearly impossible to decompose, and it ends up in landfills and the
ocean, harming marine life.
This frequently entails the destruction of plant life and the endangerment of
nearby wildlife.
Furthermore, waste management is unable to successfully recycle most
plastic (even those marked for recycling), resulting in the majority of plastic
trash ending up in landfills or the ocean.
4. Bottle & Container Caps
Bottle & Container Caps account for 15.5% of pollution in the environment as
a whole.
Caps are harmful to the environment because they float on the surface of the
water and seem like a tempting meal for birds.
Healthcare Industry
Plastics have been extensively used in the healthcare industry (25%) in the
manufacturing of surgical gloves, syringes, insulin pens, IV tubes, catheters,
inflatable splits, and other medical tools and devices.
5. Sources of Plastics
Food Wrappers & Containers
Food Wrappers and Containers account for 31.14% of pollution in the
environment as a whole.
Modern food packaging makes food safe, dependable, shelf-stable, and sanitary.
Unfortunately, the majority of food packaging is single-use and cannot be
recycled.
Fishing Nets
Many parts of the world rely on commercial fishing for a living, and millions of
people eat fish on a daily basis.
However, in numerous ways, this industry has contributed to the problem of
plastic pollution in the oceans.
6. Plastic Bags
Plastic Bags account for 11. 18% of pollution in the environment.
The inherent evil of plastic bags is well established by now, and reusable bags
have mostly entered the mainstream - but unfortunately, this hasn't resulted in a
big reduction in plastic bags.
These are extremely long-lasting, and just 3% of them are recycled.
Straws and Stirrers
account for 8.13% of pollution in the environment.
Straws have no way of recycling, which should be prohibited.
In other words, even if there is a need, there is no method to recycle straws.
On a daily basis, a huge number of straws are used (roughly 500 million per day
in the U.S. alone).
7. Beverage Bottles
Beverage Bottles account for 7.27% of pollution in the environment.
The process of water bottling emits 2.5 million tonnes of carbon dioxide into
the environment each year.
Bottles recycle at a reasonably high rate of 74 %, depending on the kind of
plastic used.
Tourism Industry
Through the construction and creation of infrastructure and services, tourism
increases the amount of plastic washed into the oceans.
Agricultural Industry
Polymers enable farmers, foresters, and fishermen to retain livelihoods, improve
productivity, reduce crop losses, and conserve water in a variety of ways, from
mulching and irrigation to fishing gear and greenhouse films.
8. Construction Sector
The construction industry is the second-largest consumer of
plastic, accounting for 20 percent of all plastic waste.
They are anticipated to produce 300 metric tonnes of plastic every year,
with half of that being single-use.
The most common uses of polymers in construction
are piping and conduit, which account for 35% of total output.
