With the increasing focus on environmental protection and energy conservation, new eco-friendly and non-burning building materials have gained popularity and are now opening up new opportunities for entrepreneurs. Starting a business in this sector can be highly profitable—whether by producing these green building materials or manufacturing the equipment needed for their production. For those with limited capital but a strong desire to start a business, using invalid patents can significantly reduce initial costs and make it easier to enter the market. Zhengzhou Yixin Heavy Machinery Co., Ltd. is a leading manufacturer of innovative brick-making equipment, including the **Mianshaozhuanji** machine. This equipment is designed to produce high-quality bricks without burning, helping to reduce clay waste and minimize environmental impact. As a key player in the non-burning brick machine industry, Zhengzhou Yixin has developed advanced technology that is now exported globally. Their products are well-received by customers around the world due to their efficiency and sustainability. If you're looking to start your own business, consider leveraging old or expired patents. These are no longer protected by law, which means you can use them at a much lower cost. Invalid patents often result from the patent holder failing to renew fees or other reasons. Additionally, some foreign patents may also be used as long as your products are not sold within the patent’s protected region. For example, patents related to ash composite bricks, fly ash-based building materials, steam-free non-burning bricks, and hollow brick machines are all available for use. These patents offer great potential for entrepreneurs who want to enter the green building materials market.
