To address these issues, a photocurable AESO emulsion was blended with a degradable cross-linker, oligoacrylate lactide/glycolide, to enhance the recyclability of the coated paper. In a parallel approach, epoxidized soybean oil (ESO) was modified with glycolic and methacrylic groups to further promote the recyclability of the coated paper. In both cases, emulsions were prepared, cast onto paper, and UV-cured prior to testing for water and oil resistance using a Cobb-1800 and kit rating tests, respectively.

This initiative advances new construction technologies by developing cement-free wall putty. Industrial activities generate calcium-rich byproduct waste on million-ton scale, which is often disposed of in the open environment, leading to its accumulation in landfills. Production of a large volume of industrial calcium byproduct waste creates serious environmental challenges and several negative consequences like depletion of soil fertility, impact on biodegradation processes, etc. Although utilization of industrial byproduct waste in solid waste management has been extensively documented in scientific literature, to the best of our knowledge, research on the utilization of calcium byproduct waste for the development of cement-free wall putty remains unexplored so far. However, commercially available wall putty is composed of dolomite, white cement, and cellulose polymer additives. The outlined scheme utilizes calcium byproduct waste of the acetylene gas industry and pulp industry as calcium hydroxide and calcium carbonate, respectively. Despite the modification in raw materials, the resulting wall putty exhibits properties and performance almost similar to those of commercially available wall putty with the added advantage of being safe and free from heavy metal ion contaminants. The unique selling proposition of this putty powder lies in its low carbon footprint as a construction material, free from white cement. Additionally, it offers superior performance by resisting cracking and flaking of paints, ensuring long-lasting and durable wall finishes. The X-ray diffraction profile of the putty powder reveals the crystalline structure of the calcite and portlandite phases. SEM studies show an agglomerated structure due to attractive van der Waals interactions of the putty paste containing hydroxyl functionalities with the polymer matrix. Scalable strategies outlined in this article not only align with domestic technological development but also promote the waste-to-wealth approach, contributing to recycling and reuse of byproduct waste.

However, synthesizing large quantities of crystalline graphite powder from plastic waste, particularly polyethylene (PE), remains a challenge because PE decomposes into light gases during thermal processing and simple methods do not exist at any appreciable size scale to address this challenge. In this work, a method is developed for air processing bulk forms of PE waste to create stable carbon char that does not readily decompose during high-temperature processing. This method employs solid additives in the form of salts, which are combined with the PE melt during air processing to increase the effective surface area of the melt and improve the oxygen-driven chemistry that stabilizes PE for high-temperature processing. After removal of the solid salt additives from the PE-derived char, it is converted into a highly crystalline bulk graphite powder using an Fe-based catalytic process. The PE-derived graphite anode in a lithium-ion coin cell showed a specific capacity of 345 mAh/g at 0.05C with an initial Coulombic efficiency of 87% and reversible capacity retention of ∼100% at different current rates. It also showed a specific capacity of up to 313 mAh/g at 0.5 discharge/charge cycles per hour (0.5C) and Coulombic efficiency of 99.9% after 250 cycles, indicating excellent electrochemical performance as an anode material for lithium-ion batteries.
