Valorization of mixed office waste as macro-, micro-, and nano-sized particles in recycled paper containerboards for enhanced performance and improved environmental perception

Redesigning the appearance of recycled containers for packaging applications: The effect of paper waste physicochemical properties on the performance of paperboards with obvious recycled content

“…The apparent aspect ratio of the produced CMFs was 163 15 . The complete characterization of this material is available in Chacon et al 15 …”

“…Despite the enhanced environmental perception instilled by the presence of visible recycled material in the packaging, the redesigned containers can have lower mechanical performance than their non‐modified analogues. In our previous work, it was shown that the apparent size of waste particles that were incorporated in a recycled fibre matrix had a more detrimental effect on the mechanical properties of the redesigned recycled containers than their weight ratio (wt%) (between 5 and 40 wt%) 15 . Large waste particles (with an apparent aspect ratio of 52) disrupted the inter‐fibre bonding network more significantly than small particles of larger apparent aspect ratios (72 and 163 in the reported study 15 ), which resulted in a 20% decrease in the paperboard strength 15 …”

A Global Look at the Market Potential of Liquid Container Board and Its Ability to Reduce Plastic Waste – A Brief Review

“…However, using paper for packaging and containers makes a substantial amount of paper waste. In 2022 the paper industry in the United States produced 67 million tons of waste from paper products and recycled 68 percent of that waste [29].…”

Developing Alternative, High-Absorbency Brown Fibers: Tissue Paper from Upcycled Corrugated Packaging Waste to Meet New Consumer Trends

“…Based on the current situation, there is an opportunity of using OCC to obtain an alternative brown fiber suitable to produce high-performance unbleached tissue products. The development of this type of fiber is based on the following rationale: OCC could contribute to improving the sustainability efforts currently undertaken by the tissue industry. ,, This is mainly due to the lower environmental footprint of unbleached pulps (high lignin content) compared to bleached pulps, which require the use of bleaching chemicals to reach their characteristic high brightness. ,, In addition, the brown color, perceived in some cases as sustainable, could be used as a marketing advantage for manufacturers competing in the eco-friendly product segment or planning to take a share of this market. ,, Nonetheless, the premium tissue sector composed of bleached products will remain to have the biggest market share The incorporation of upcycled OCC into value-added products can be translated into less generation of landfilled or combusted packaging waste, meaning a substantial decrease of CO 2 -equivalent emissions. , Additionally, the substitution of virgin fibers by secondary fibers can contribute positively toward the material balance on forest growth and recovery of forest lands. − …”
