Германия− одна из стран, уверенно лидирующих по количеству экологически чистых и выгодных экономике страны разработок, постепенно внедряемых в обиход. Ежегодно патенты получают десятки подобных изобретений. В числе разработок прошлого года значится изобретение, по праву претендующее на звание новейшего экологического прорыва, совершенного учеными за последнее время в области строительных материалов. Группа ученых университета Фрайбурга (Германия) сегодня продолжает заниматься продвижением проекта Biofoambark, одним из направлений которого является создание изоляционной пены с основой из натуральных компонентов. В качестве сырья для первой подобной разработки было решено взять отходы древесной промышленности. После специального отбора из сырья извлекли танин, содержащийся в коре любого дерева. Первая попытка оказалась настолько успешной, то пока разработки ведутся только в данном направлении.
Танин подвергают специальной обработке, после которой он становится пригодным для изготовления жесткого пенопласта с высокими изоляционными свойствами. К тому же, на выходе получают материал, обладающий повышенной огнестойкостью. По мнению ученых, их разработка со временем сможет создать серьезную конкуренцию токсичному пенопласту (пенополистиролу), сейчас пользующемуся наибольшим спросом среди потребителей.
Главный козырь био-пены − экологичность продукта, а также использование вторсырья. Поначалу такой продукт может стоить дороже, но цена со временем спадет: стоит только выйти на рынок и заинтересовать потребителя.
После ряда успешных разработок экологический проект Biofoambark заинтересовал Ассоциацию университетов Фраунгофера. Все исследования, проводимые в рамках данного проекта, получили непосредственную поддержку правительства Германии, а также финансирование от коммерческих и промышленных партнеров − Италии, Испании, Словении, Франции и Финляндии.

And this task could be cheap jerseys handled well, if the KFA is able to conduct its annual tournaments for the various age groups in a more systematic cheap nfl jerseys manner.

The Chargers were completely dominated, losing 33 3 in a game that was even more one sided than the score suggests. What’s surprising is that the Chargers do not have an inherently untalented team. Philip Rivers is still considered by many as a top franchise quarterback, one that several GM’s may well sell the farm for come the off season.
