Beyond the blue bins: New American Chemical Society video on recycling

April 20, 2012
Just in time for Sunday's celebration of Earth Day, the American Chemical Society (ACS) today released a video revealing the journey that recyclable materials take beyond those blue curbside bins. In the latest episode of ACS' award-winning Bytesize Science series, viewers take a tour of a typical recycling center to see how these facilities sort the mountains of recyclables they receive every day. The video is available at www.BytesizeScience.com.

It points out that the average American generates about 4.5 pounds of trash every day. That's almost 250 million tons of waste every year - enough to bury more than 93,000 football fields in six feet of trash. Less than 25 percent of that is recycled. The rest winds up being burned or buried in landfills. Scientists say we could reuse or recycle more than 70 percent of that waste, which includes valuable materials like glass, aluminum and paper.

The video shows how the Montgomery County (Maryland) Recycling Facility in suburban Washington, DC, serves as one of the first links in the recycle-reuse chain. It receives more than 80,000 tons of mixed plastic, aluminum and other recyclables every year, and uses staff and machinery to sort out the various materials. Machines later compress the materials into large blocks - or "bales" - that can be made into new products. Those trashed aluminum cans, for instance, may become the engine block or alloy wheels in a new car or truck. Scrap paper may get a new life in tomorrow's newspaper, paper bags or other products.

Chemistry: A General Chemistry Project of the American Chemical Society

Chemistry: A General Chemistry Project of the American Chemical Society
by American Chemical Society (Author), Jerry A. Bell (Author)


The American Chemical Society has launched an activities-based, student-centered approach to the general chemistry course, a textbook covering all the traditional general chemistry topics but arranged in a molecular context appropriate for biology, environmental and engineering students.  Written by a team of industry chemists and educators and thoroughly class-tested, Chemistry combines cooperative learning strategies and active learning techniques with a powerful media/supplements package to create an effective introductory text.

Chemistry in Context

Chemistry in Context
by American Chemical Society (Author)


Following in the tradition of the first six editions, the goal of this successful, issues-based textbook, Chemistry in Context, seventh edition, is to establish chemical principles on a need-to-know basis for non-science majors, enabling them to learn chemistry in the context of their own lives and significant issues facing science and the world. The non traditional approach of Chemistry in Context reflects today's technological issues and the chemistry principles imbedded within them. The seventh edition applies sustainability principles wherever possible. Global warming, alternate fuels, nutrition, and genetic engineering are examples of issues that are covered in Chemistry in Context.

Reagent Chemicals: Specifications and Procedures (American Chemical Society, Committee on Analytical Reagents// Reagent Chemicals: American Chemical Society Specifications)
by ACS Committee on Analytical Reagents (Author)


The American Chemical Society Committee on Analytical Reagents is the only organization in the world that sets requirements and develops validated methods for determining the purity of analytical reagents. For the first time, Reagent Chemicals, 10th Edition includes general physical properties and analytical uses for all reagent chemicals, nearly 500 chemicals. Thirty-two new reagents and three new classes of standard grade reference materials are introduced in this edition. In addition, the use of Inductively Coupled Plasma Mass Spectrometry (ICP-MS), which is recognized as the most powerful and flexible trace element technique, is now accepted as an analytical method in the 10th edition. Other improvements include a CAS number index, a separate index for standard grade reference...

Inquiry-Based Experiments in Chemistry (American Chemical Society Publication)

Inquiry-Based Experiments in Chemistry (American Chemical Society Publication)
by Valerie Ludwig Lechtanski (Author)


Students taught with inquiry-based methods have been shown to make significant progress in their ability to formulate hypotheses, make proper assumptions, design and execute investigations, understand variables, record data, and synthesize new knowledge. The inquiry-based approach encourages curiosity and openness, and fosters a stronger sense of responsibility and satisfaction in the students who are taught with it. This text presents a series of experiments that are intended to serve as the solid basis for a first-year chemistry or physical sciences course, using an inquiry based approach. Each chapter provides: 1)instructions for an experiment; 2) teachers notes that give the instructor more in-depth information about the technical nature and intellectual objectives of the...
