1.3 billion tonnes of food waste enters landfill each year, when food waste begins to decompose it releases methane gas into the environment, contributing to climate change. CO2<\/sub> emissions are often viewed as the greatest contributor to global warming<\/a>, however methane traps 30 times more heat in the atmosphere.<\/p>\n Once discarded, uneaten food occupies almost 1.4 billion hectares of land, which amounts for 30% of the world\u2019s agricultural land area. Food wastage, followed by its improper disposal, limits the area of land in which farmers can produce food and results in the loss of habitat for local wildlife.<\/p>\n Several organisations are aiming to reduce the amount of food waste that is sent to landfill by using it to develop biomaterials. These materials play an integral role in modern medicine, providing healthcare professionals with essential technologies for those with heart conditions<\/a>, artificial joints<\/a>, cranial implants<\/a>, and skin grafts<\/a>.<\/p>\n Innovation in the field of bone regeneration is essential to ensuring the fixation of artificial joints\/implants, dental fixators, closure of cranial defects in various injuries, etc. Researchers at National University of Science and Technology<\/a>, Russia, have developed a bioactive polymer-ceramic composite for fixing implants and restoring bone defects in the skull. The biomaterial is derived from eggshells and increases the strength and biointegration of implants.<\/p>\n According to Inna Bulygina, co-author of the study, the use of eggshells in bone generation contributes to bone mineralisation and growth. Bulygina added: \u201cWe have adopted a cost-effective approach to recycling biowaste to improve the quality of life for patients with bone disease. For the production of composites, diopside obtained from eggshells was used.\u201d<\/p>\nBiomaterials for bone regeneration<\/h3>\n
