Plastic waste management- Conventional and New Technology
Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.

- Plastic roads can be made from waste plastic which is a more durable and cost-effective alternative to normal roads. The process involves shredding waste plastic, mixing it with heated bitumen, and laying the mixture on roads.
- Mixing plastic with bitumen increases the melting point and flexibility of roads while overcoming brittleness. This results in roads with longer lifespans that are more resistant to damage from rain.
- Plastic roads require less bitumen, have improved bonding between materials, prevent moisture absorption and cracking, and show greater compressive strength than normal roads. They provide a smoother ride and more durability.
plastic in road construction
This document discusses using plastic waste in road construction. It begins by outlining the process, which involves segregating, cleaning, shredding and collecting plastic waste. There are two methods for incorporating plastic into roads - a wet process that mixes plastic directly with hot bitumen, and a dry process where plastic coats heated aggregates before adding bitumen. Using plastic in roads provides benefits like increased strength and reduced costs, while helping address the problem of plastic waste. However, there are also potential disadvantages like toxic chemical leaching during construction and use. Overall, plastic roads present an environmentally-friendly way to strengthen pavements and reduce plastic pollution.
Application of waste plastics in construction of roads
This document discusses using waste plastics in the construction of roads. Plastic waste is collected, cleaned, shredded, and mixed with heated aggregates and bitumen to create a plastic-coated aggregate mix. Laboratory studies found that incorporating waste plastic into bituminous road mixes enhances the properties of the mix, improving characteristics like aggregate impact value and resistance to abrasion. Using waste plastics in road construction provides a solution for plastic disposal while strengthening and increasing the lifespan of roads.

Plastic can be used in the construction of flexible pavements as it is inexpensive, strong, and durable. Plastic waste is collected, cleaned, shredded, and mixed with heated aggregate and asphalt. This results in a plastic-coated aggregate mix that is stronger and more resistant to wear than a conventional mix. Using plastic waste in roads reduces costs and bitumen needs while helping to dispose of plastic waste. However, there are concerns about chemicals leaching from the plastic during and after road construction. Some initial plastic roads in India have shown promising results in strengthening pavements and increasing their lifespan.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
