Construction and demolition (C&D) activities are among the largest contributors to global waste generation, accounting for millions of tons of debris annually. As urbanization accelerates, sustainability has become a crucial focus for the industry. Recycling and reuse practices are now integral to reducing environmental impact while promoting resource efficiency. The circular economy concept is guiding stakeholders to shift from a “take-make-dispose” model to one where materials are repurposed and given extended lifecycles.

Concrete, wood, asphalt, metals, and plastics dominate C&D waste streams. Recycling concrete into aggregates for new construction projects not only reduces landfill pressure but also cuts down on the demand for virgin raw materials. Similarly, metals such as steel and aluminum can be endlessly recycled without losing strength, making them valuable assets in sustainable building practices. Timber from demolition sites can be processed into engineered wood products or used in biomass energy production.

Biaxially Oriented Polyethylene Terephthalate (BOPET) films have emerged as one of the most widely used specialty films across packaging, electronics, and industrial applications. Known for their excellent tensile strength, thermal stability, transparency, and gas barrier properties, these films have gained popularity among industries that demand durability and functionality. The global market for BOPET films has been on a steady rise, driven by the surging demand for sustainable packaging, advancements in flexible electronics, and the rapid growth of e-commerce.

The food and beverage sector remains the largest consumer of BOPET films. Their superior moisture resistance and oxygen barrier capabilities extend product shelf life, making them a preferred choice for snack packaging, ready-to-eat meals, and carbonated beverages. The cosmetic and pharmaceutical industries are also fueling demand due to the need for safe, attractive, and durable packaging solutions.

Another factor boosting the market is the technological shift in electronics. With miniaturization and flexible displays…

In recent years, the cups and lids industry has undergone a significant transformation as sustainability has moved to the forefront of consumer demand and corporate responsibility. With growing awareness about environmental challenges, particularly the impact of single-use plastics on oceans and landfills, manufacturers and foodservice providers are under immense pressure to adopt greener alternatives. Cups and lids, once seen as disposable commodities, are now at the center of innovation and regulatory changes that are shaping the future of packaging. From biodegradable materials to reusable solutions, the market is redefining its role in a circular economy.

One of the biggest shifts in the industry has been the transition toward biodegradable and compostable materials. Companies are investing heavily in research and development to create cups and lids from plant-based polymers, sugarcane, bamboo, and even recycled paper. These products are designed to break down naturally without leaving harmful residues, appealing to environmentally conscious consumers. Many…

Escalators are among the most familiar yet often overlooked machines in our daily lives. Whether at a bustling airport, a crowded shopping mall, or an underground metro station, escalators move millions of people every day without much fanfare. But behind their quiet efficiency lies a fascinating story of invention and evolution that stretches back more than a century. The concept of a moving staircase was first envisioned in the mid-19th century, with several patents filed, but it was Jesse W. Reno who successfully introduced the first working escalator, known as an “inclined elevator,” in 1896. Installed at Coney Island, it was initially more of an amusement ride than a serious mode of transportation. Soon after, Charles Seeberger partnered with the Otis Elevator Company to refine the design, creating a system that included the distinctive steps and comb plates that remain central to escalator technology today.

In the early 20th century, escalators quickly…
