Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.

  • The Euro pallet, also known as the European Pallet or Europallet, is a wooden pallet that adheres to specific dimensions and standards established by the European Pallet Association (EPAL). The standard size of a Euro pallet is 1200 mm x 800 mm (approximately 47.2 inches x 31.5 inches), making it a versatile choice for transporting various types of goods. Euro pallets can carry a maximum load of 1500 kg, enabling them to accommodate a wide range of products, from food and beverages to industrial materials.


  • Moreover, different dustbins make it easier for municipalities to track and manage waste. By analyzing the volume and type of waste collected from various dustbins, city planners and environmental officials can identify trends, spot inefficiencies, and develop better strategies for waste reduction. This data can guide initiatives that aim to minimize waste generation at the community level and encourage practices such as composting or bulk buying to reduce packaging waste.


  • 3. Durability Made from strong materials, cast iron repair clamps are designed to withstand high pressures and harsh environmental conditions. Once installed, they can provide a long-lasting solution to leaks and breaks, extending the life of the cast iron system.


  • Why am I responsible for the manhole on my property?
    Many Homes have a manhole located on their property typically constructed by the developer of the housing plan. This manhole gives the Sanitary Authority access to our sewers for routine maintenance and emergency work. When your house was constructed, the top of     the manhole was placed at grade, or ground level. Over time, residents and landscapers inadvertently cover over the manhole with grass, build planter boxes around manholes, or cover over the manhole with mulch.

  • By fostering a sense of appreciation for these often-overlooked elements, we can cultivate a deeper understanding and connection to the systems that keep our cities thriving.
