EPA used statistics from the American Forest & Paper Association (AF&PA) to estimate post-consumer paper and paperboard generation in 2018. The total generation of paper and paperboard in MSW was 67.4 million tons in 2018, which was 23.1 percent of total MSW generation that year.
Chemical properties of MSW are very important in evaluating the alternative processing and recovery options. Used primarily for combustion and waste to energy (WTE) calculations but can also be used to estimate biological and chemical behaviours. Waste consists of combustible (i.e. paper) and non-combustible materials (i.e. glass).
It is a kind of waste material that comes from the sugar industry. It is most commonly used in paper industries, but researchers have suggested that different mechanical and chemical treatments can help to extract cellulosic fibers, pure cellulose, cellulose nanofibers, and cellulose nanocrystals. ... The chemical composition of …
The search for non-wood fibers as alternative to the limited wood fiber resources is highly imperative in the pulp and paper-based industries. This is due to growing environmental concern as a result of excessive deforestation. This study aimed at investigating the pulp and paper potentials of pineapple crown (Ananas comosus), …
Some researches made a chemical assessment of paper industry waste; one used sludge coming from the tissue paper industry, to remove dying, with similar visual features to the waste used in this research (extremely humid and greyish). This waste predominantly has in its chemical composition CaO (19.95%), SiO 2 (7.44%), and Al 2 …
