While many people wring their hands over the amount of plastic waste, Miranda Wang aims to reduce the mess. Ms. Wang, 24, is a co-founder and chief executive of BioCellection, a start-up that is tackling hard-to-recycle plastic packaging, focusing initially on plastic-film waste. Using a novel reaction system that employs a liquid chemical catalyst, BioCellection turns unrecyclable, contaminated film waste into chemicals that can be used by consumers and industry. Later this year, BioCellection will start a pilot program in the San Francisco Bay Area to build its first commercial machine, which can process five metric tons of waste a day. Many borrowers with poor credit scores ... can't qualify for an affordable small loan. Jeff Zhou is offering an answer, in the form of Fig Loans. The lender's goal is to offer an alternative to pricey payday loans that strapped consumers turn to when they have an unexpected financial emergency and have no other option. "We want to offer socially responsible financial products for people who are under banked," he said. Customers can apply online for a loan from Fig, which makes lending decisions based on bank statements, taking into account expenses like rent, utilities and spending, Mr. Zhou said. Loans are $300 to $500 and, depending on the state, are repaid in four or six equal monthly installments - unlike payday loans, which typically must be repaid in two weeks.
