Yes — there are some Jain-related organizations and trusts that say they collect old religious items, including idols and temple-related things, for preservation, restoration, or respectful handling. For example, Sampurnam Foundation says it collects religious idols, statues, books, mandirs, and related items, and Acharya Shanti Sagar Foundation says it works to preserve Jain cultural and spiritual heritage. ( sampurnam.org)

If your item is an old Jain idol/pratimaji, it is better to give it only to a trusted Jain temple, sangh, or Jain trust that understands the proper Jain way of handling such items. This is especially important for sacred objects. ( shantisagarfoundation.org)

If you want, I can also help you with the proper Jain way to hand over old idols or temple items.
