A baler is a machine used in agriculture and waste management to compress and package materials like hay, straw, or recyclables into compact bales. These bales are easier to handle, transport, and store. There are different types of balers, including round balers and square balers, each designed for specific materials and uses. Balers can be found in farms and recycling facilities, helping to streamline the process of managing bulk materials. They play a crucial role in reducing waste and improving efficiency in various industries, making it easier to transport goods and manage resources effectively.
