From the Manufacturer The Post-it Note was invented as a solution without a problem. In 1968 Dr. Spencer Silver, a 3M scientist, developed a unique, repositionable adhesive. As remarkable as it was, the product could not find a market. Six years later, colleague Art Fry recalled Silver's seminars promoting the light adhesive when he was daydreaming about a bookmark that would stay put in his church hymnal. The rest is history. Today, Post-it boasts more than 4,000 unique products and has become one of the most well-known and beloved brands in the world. Are All Post-it Paper Products Recyclable? Yes. 3M has conducted recycling trials on Post-it Notes at recycled paper mills. The adhesive does not interfere with paper recycling, because the adhesive is substantially removed in the paper de-inking process. The dyes in the paper are also removed in this part of the process. Are Post-it Notes Made from Recycled Paper? Yes. Many different colors and sizes of Post-it Notes are available with paper containing at least 30 percent post-consumer recycled content. In addition, 3M offers 100 percent recycled content notes in canary yellow and assorted pastel colors. The 100 percent recycled content notes contain 70 percent pre-consumer and 30 percent post-consumer fiber. Post-it Easel Pads are also available with 30 percent post-consumer content paper.
