Why cutting food waste soon could get easier | GreenBiz - 0 views

  •  
    Four representatives recently introduced a bill called the Food Donation Act of 2017 (H.R. 952), which addresses some of the greatest barriers that restaurants and food service companies face when they want to give away their excess edible food. This bill clarifies and enhances the coverage areas of the Bill Emerson Good Samaritan Food Donation Act, the legislation that made the donation of excess food from businesses to people in need legally protected.

Maharashtra: Engineering students invent pollution-control device | Latest News & Updat... - 0 views

  •  
    Four mechanical engineering students from Nashik have invented a device which is an indicator for the vehicle driver about excessive pollutant levels, while driving. When the engine of the vehicle starts, the sensor fitted in the silencer will sense the exhaust particles and check the limit value. If it exceeds the prescribed limit then a red light will blink as the first indicator, for two hours. Even after the first warning, if there is no change in the limit then there are two more indicators that will blink within a gap of two hours after which the engine will automatically turn off. According to the four inventors, the device will help in tackling the pollution issue, especially in densely-populated and polluted areas.

    Danish city officials announced the completion of what they claim to be the world's first neighborhood adapted for climate change in Copenhagen: the St. Kjeld neighborhood has been retrofitted with mini-parks, rooftop water collection, and raised sidewalks to direct excess water from extreme weather events and rising sea levels towards the harbor.

How Long Can Oceans Continue To Absorb Earth's Excess Heat? by Cheryl Katz: Yale Enviro... - 0 views

    The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans' heat-buffering ability may be weakening.

Changing the Culture of Excess [Packaging] | Sustainable Brands - 0 views

  •  
    Often taking up more than half of a product's unit volume, some studies indicate that product packaging accounts for nearly half of all household waste. Simple, powerful solutions for reducing packaging waste lie in finding more efficient ways to meet consumer demands. The adoption of manufacturing practices that satisfy marketing and quality requirements without over-packaging goods would be a great and necessary shift for more sustainable production standards.
