Will a bio additive for accelerating mafic rock weathering by at least 30%, which enhances its CO2 sequestration, be available before 2030 and cost less than $20 per ton of rock?

Cheap bio additive ↑ rock weathering 30%? → 0.5Gt CO2 removed by rock weathering by 2040?

When will direct air carbon capture tech cost <$50 (2020 USD) per ton of CO2?
