Boi boosts leather industry's capacity with new financing scheme

I think there may be a small mistake in your sentence. It seems like you meant to say "BOI" (Board of Investment) rather than "boi" (which is a colloquial term for a boy).

Assuming that's the case, here's a rewritten version of your sentence:

The Board of Investment (BOI) boosts leather industry's capacity with new financing scheme.

This sentence suggests that the BOI has introduced a new financing scheme that aims to increase the capacity of the leather industry. This could involve providing loans, grants, or other forms of financial support to leather manufacturers, tanneries, or other businesses in the industry. The goal of this scheme is likely to stimulate growth, improve efficiency, and increase competitiveness in the leather industry.
