PAPER SLUDGE YIELDS RENEWABLE FUELS

Scientists found paper waste can make renewable fuels like bioethanol and biogas. This helps manage waste and reduce fossil fuel use.

Paper sludge, which creates 500 million tons of waste yearly, can now be turned into useful biofuels. This is a new way to use waste.

HIGHLIGHTS
🛬 Provides a model for a credible and reliable net-zero pathway.
✈️ Shows that business-as-usual scenarios will deplete remaining carbon budget.
✈️ Argues that CO2-price and 4%/yr−1 drop-in quota necessary for transition.
✈️ Highlights the central role of climate governance in creating markets.
✈️ Concludes that new business model for aviation needed.

"Key transition technologies are in early stages of technology readiness, their scalability is uncertain, and airlines are not profitable. The replacement of fossil fuels will demand drop-in quota legislation at a global scale."

"If the current business model – volume growth with very small profit margins – is continued, it is likely that aviation's contribution to climate change will grow, due to constraints in biofuel production, cost, and an increase in non-CO2 warming. To stay within 1.5 °C warming, the sector has to reassess capacity and its relationship with profitability; and to possibly embrace an altogether different business model."
