When a corporate entity files for Chapter 7 Bankruptcy (liquidation), the business is essentially asking the bankruptcy trustee to manage the liquidation of corporate assets. The trustee will take any assets of value and distribute those assets to the creditors in order of priority.
A corporate entity does not receive a discharge of debts at the the end of the bankruptcy. Any assets which were not distributed by the trustee are abandoned back to the business which must now be dissolved by the owners. The owners may be subject to collection on debts of the company if they personally guaranteed any of those debts or failed to appropriately separate their personal and corporate assets. However, any strictly corporate debts not satisfied in the bankruptcy are owed solely by the corporate entity and any property abandoned back to the business could still be collected pursuant to state collection laws.
Practically speaking, any assets abandoned back to the business are probably so invaluable as to not be worth collecting. Once any remaining corporate debts are paid, the business can be dissolved and any remaining assets distributed to the owners.
