Since a new tree can be grown where a mature tree has been harvested, wood is an ideal natural resource for biomaterials. This biomass cycle continually sequesters carbon dioxide.
Traditionally the papermaking process has only used approximately half of the raw wood material to manufacture pulp and paper products. The balance of the raw material isused to generate energy to power the mill or to sell into the electricity grid. Sappi is, however, developing new processes and biomaterials which extract more value from each tree and supports our business strategy to move into new and adjacent markets.
Sappi’s patented process, developed with Edinburgh Napier University, reduces the energy required to process woodfibres into nanocellulose thus enhancing our product’s sustainability.
Lignosulphonate is a highly soluble lignin derivative and a product of the sulphite pulping process.
Hemicellulose sugars from trees are referred to as second generation sugars and do not compete with food crops unlike first generation hemicellulose sugars from agricultural crops.
Sappi is focusing on green energy generation in line with our strategic focus to derive value from energy opportunities and in light of sustainability and efficiency drivers.
